Menus and Settings

The WDD-LITE provides a menu system for device settings, base station configuration, system information, and advanced functions. Open the menu by long-pressing the screen from the main display, or by tapping the gear icon in the top-right corner.

Menu Navigation

• Swipe up / down (or flick) to scroll the list
• Tap an item to activate it
• Swipe right to go back from most sub-screens. On a list screen, you can also tap the title at the top.
• The Select Source device list is the one exception. Tapping its title does nothing. Tap a device, or swipe right to search again.
• Pair WVC and Pair Knob work differently. See Pair WVC and Pair Knob.

Menu rows have a small icon next to their name. It helps you find an item fast. System Info shows an eye. Settings shows a gear. Base Info shows a wireless symbol. Base Settings shows a list.

• Settings: Orientation, Volume Units, Playback, Enable High Speed, Auto Swap, Sleep, Colors, WiFi, Camera, and Back each have an icon. Brightness, Temp Units, Min/Max, Swap Time, the Auto Swap view rows, and Sleep After have none.
• Advanced: Update Firmware and Repair Firmware show a download icon. Update Base shows an upload icon. Pair WVC and Pair Knob show a plus icon. Channel Groups shows a list icon. Smart Home shows a home icon. Forget Phones shows a Bluetooth icon. Forget Base and Factory Reset show a trash icon. That way you can spot them before you tap.

Menu Structure

Settings

Device-level settings for the WDD-LITE itself. Changes are saved automatically.

Setting	Type	Options / Range	Description
Brightness	Slider	10-100%	Display brightness level. Applies immediately as you adjust it.
Orientation	Navigation	(sub-menu)	Set the display orientation: Landscape, Landscape Flipped, Portrait, or Portrait Flipped. The display restarts to apply your choice. Default is Landscape.
Volume Units	Toggle	dB / %	How volume is shown on the Volume console and the top-bar glance
Temp Units	Toggle	°F / °C	Temperature display units. Only visible when connected to a base station that supports temperature probes (WVC-PRO / WVC-PRO 6). With firmware 4.15.4 or newer, it also sets the temperature on Now Playing.
Min/Max	Toggle	All-Time / Window	Controls the min/max readout under the Volts view. All-Time shows the lowest and highest values since power-on; Window shows the lowest and highest values currently visible in the trend graph.
Playback	Toggle	On / Off	Shows the playback bar at the bottom of the screen. Its buttons control the music on your phone. Off hides the whole bar. A new display, or one after a Factory Reset, starts with On. After an update, it keeps its old setting, which may be Off. On an Android phone, the bar can show more. It can show the song, how far into it you are, and the Song list button. These need the LF Audio app. They also need the latest firmware on both of the base station's processors. The song and its time need Song list on in the app. With Song list off, the Song list button still shows while the app is connected. Tap it to see how to turn Song list on. With WDD-LITE firmware 4.15.4 or newer and base station firmware 4.22.0 or newer, the bar and Now Playing can also show the song's cover. See Song covers. This row appears only with a WVC base station on firmware 4.11.0 or newer on both of its processors. See Playback Controls and Song list.
Enable High Speed	Toggle	On / Off	Asks the connected base station to send data to the display over the faster wireless mode instead of the long-range one. It is a request, not a command: the base station speeds the link up only when the display is close enough and its own firmware supports it. When it does, the FFT and Scope views refresh several times faster. With firmware 4.15.4 or newer, the song's cover can also show behind Now Playing. When the setting is off, the link stays in the long-range mode, which reaches furthest. Takes effect within about ten to twelve seconds, with no restart. Default On. See High Speed Link.
Auto Swap	Toggle	On / Off	Automatically cycles the main display through the available mode tabs that are set to Show
Swap Time	Slider	2-60s	How long each mode is shown before switching (appears only when Auto Swap is on)
Volts, Volume, Temp, FFT, Scope, Waterfall	Toggle	Show / Hide	One row per view. Set a view to Hide to leave it out of the cycle. You can still tap its tab or swipe to it. Only the views your base station offers are listed. All are set to Show at first. These rows appear only when Auto Swap is on.
Sleep	Toggle	On / Off	Battery-equipped units only. Puts the screen to sleep after a period without touch, to conserve the battery. Sleep applies only while the display is running on its battery: with external power connected the screen stays on. Default On.
Sleep After	Enum	30 or 45 sec, or 1, 2, 5, 10, 15, 20, 30, 45, 60, 90, or 120 min	How long the display sits untouched before the screen sleeps (appears only when Sleep is on). Default 20 minutes.
Colors	Navigation	(sub-menu)	Opens the Colors menu: pick a built-in theme, edit the gradient, or override individual element colors
WiFi	Navigation	(sub-menu)	Manage the WiFi networks used for firmware updates. See Firmware Updates
Camera	Navigation	(sub-menu)	Opens the camera settings. Enable Camera turns the camera view on or off. It is Off by default. The other rows set up the picture.

Orientation

Set which way the display renders in Settings > Orientation. Four options are available: Landscape (the default), Landscape Flipped, Portrait, and Portrait Flipped. Pick the one that matches how the unit is mounted. Two choices show: Rotate & Restart and Cancel. Rotate & Restart ignores a tap right after it appears. Wait a moment, then tap it. The WDD-LITE restarts to apply your choice. Your choice is kept when you use Forget Base, and is reset to Landscape by a Factory Reset.

High Speed Link

The WDD-LITE and your base station can talk in one of two wireless modes. Long Range mode reaches the furthest and is the safe choice when the two units are far apart or separated by metal panels. High Speed mode carries more data, which makes the FFT and Scope views refresh several times faster.

Settings > Enable High Speed controls which one the display asks for. It is On by default, since a WDD-LITE is normally mounted in the dash where range is rarely the limiting factor.

Turning it on is a request rather than a command. The base station makes the final decision and speeds the link up only when the display is close enough to it and its own firmware supports the faster mode. With the setting off, the link stays in Long Range mode whatever the conditions.

There is no restart. The change takes effect within about ten to twelve seconds, and the LR / HS label beside the signal-strength meter in the top bar shows which mode is actually in use. See Link Mode.

Sleep (Battery-Equipped Units)

On a WDD-LITE fitted with the optional battery, the screen sleeps after the period set in Settings > Sleep After to conserve charge. Tap the screen to wake it; the display comes back to the same view you left it on. Plugging the display in also wakes it.

Sleep is suspended whenever the display is on external power, so a hard-wired or USB-C-powered unit never sleeps. Turn the Sleep toggle off to keep the screen on even when running from the battery.

In Competition Mode (WDD-LITE firmware 4.12.3 or newer), the screen still sleeps after the Sleep After time. But the display stays connected to the base station. So your system does not mute or turn down. This uses more battery. If the base station turns off, the display sleeps as normal. This takes about a minute. Turn Competition Mode on while the screen is on. If the screen is off, the display misses the change. With nothing else connected, your system then mutes or turns down. Tap the screen to wake the display. Then turn the volume back up.

The Sleep and Sleep After rows appear only on a battery-equipped unit; a standard WDD-LITE never shows them.

Colors

Customize the colors used across the display, audio visualizers, and status icons. Your choices are saved automatically and survive reboots and firmware updates.

Item	Description
Theme Gradient	Edit the two-color gradient that drives the volume groups, channel views, voltage, and temperature probes. The currently active theme's name is shown here.
Presets	A list of 16 ready-made themes. LF Audio is the default. Tap one to apply it instantly. The active theme has a bright border around its swatch.
Advanced Colors	Override individual element colors one at a time. Every color slot the display uses is listed; an overridden slot is marked with a bright border on its swatch.
Reset All Colors	Restores the default LF Audio palette and clears every individual override. Tap it, then tap Confirm Reset, or Cancel to keep your colors. Confirm Reset ignores a tap right after it appears, so wait a moment first.

Available Presets

All 16 presets ship on every WDD-LITE:

LF Audio (default), Sunset, Ocean, Inferno, Mono Pink, Forest, Neon, Plasma, Lava, Ice, Apex, Bass, Crimson, Royal, Mint, and Vapor.

Using the Color Picker

When you choose a color, a picker appears with a color wheel and a brightness slider:

• Touch the wheel to set the color. The angle sets the hue, and the distance from the center sets how vivid it is.
• Drag the slider to adjust brightness.
• Tap OK to save, or Cancel (or swipe right) to discard.

WiFi

Settings > WiFi manages the networks the WDD-LITE uses to download firmware. The screen is laid out as:

Row	Value	What it does
Base WiFi	The network name	The WiFi network learned from your base station. Shown whenever those credentials are stored, whether or not you are currently connected.
Clear Base WiFi	Clear	Forgets the cached base station network. Indented under Base WiFi.
Saved Networks	e.g. 3 saved	Header for the list below, showing how many networks are stored
(one row per network)	Remove	Forgets that saved network. Indented under the header.
Add Network	Scan	Opens the WiFi scan list so you can add another network
Back		Returns to Settings

Removing a network, and clearing the base station WiFi, both require confirmation. Tapping the row shows a prompt with Confirm and Cancel, so a stray tap cannot delete stored credentials. For a saved network the prompt reads Remove and the network's name, for example Remove MyNetwork?. For the base station WiFi it reads Remove base WiFi?. Confirm ignores a tap right after the prompt appears. Wait a moment, then tap it. Swiping away without confirming cancels it, and the prompt resets every time you open the screen.

See Firmware Updates for the scan list, the two-tap keyboard, and how the display chooses a network during an update.

Base Info

Information about the connected base station. Values update automatically while this screen is open. On a WVC base station, you can also rename it here. See Name below.

Field	Description
Model	Base station model (e.g., WVC-PRO, WVC-PRO 6, WVC-LITE)
Hardware	Base station hardware version
Daughtercard HW	Daughtercard hardware version (WVC-PRO 6 only)
CPU1 FW	Main processor firmware version
CPU2 FW	Secondary processor firmware version. With a Smart Signal Analyzer, this is its daughtercard display. It shows once the analyzer has firmware 4.20 or newer and the WDD-LITE has firmware 4.14.8 or newer. It can hide for a moment while that display restarts or updates.
Sensor board FW	Firmware version of the sensor board in a Temperature Hub. Shown only with a hub that has firmware 4.20 or newer, on a WDD-LITE with firmware 4.14.8 or newer. It can hide for a moment while the sensor board restarts or updates.
CPU3 FW	Daughtercard firmware version (WVC-PRO 6 only)
Built	Base station manufacture date
Uptime	Time since the base station was last powered on
Name	The base station's name. If it shows a pencil icon, tap it to rename the base station. See the tip below.
UUID	Unique device identifier
BT Pin	Bluetooth pairing PIN. Your phone asks for it when it pairs. This row is hidden with a Smart Signal Analyzer or a Temperature Hub. Read the PIN on that device's own screen. It is also hidden with a High Precision Voltmeter.

Base Settings

Configuration options for the connected base station. Changes are sent to the base station immediately. Some settings have child options that appear or hide based on the parent value.

IDS Mode (Intelligent Drive System)

Controls how the system responds to abnormal voltage or temperature. For full details on what each mode does, see the Intelligent Drive System (IDS) article.

WVC-PRO / WVC-PRO 6 options:

Option	Behavior
Off	IDS disabled
Mute	Sets volume to 0 when triggered. Volume stays at 0 after the condition clears, so turn it back up manually.
Rem Off	Drops the Remote Out signal when triggered, turning off any amplifier wired through it. Remote Out restores automatically about 1 second after the condition clears.
Mute+Rem	Both sets volume to 0 and drops Remote Out. Remote Out auto-restores; volume must be turned back up manually.
Limit Vol	Gradually reduces volume while triggered. Volume stays at the reduced level after the condition clears, so turn it back up manually.

WVC-LITE options: Off, Mute, Limit Vol (a WVC-LITE base station has no remote-output wire, so the Rem Off modes do not apply). The WDD-LITE automatically offers only the modes your base station supports.

When IDS Mode is set to anything other than Off, these child settings appear:

• Min Voltage (slider, 6.0-18.0V, step 0.1V): the voltage threshold below which IDS triggers. Most 12 V car audio systems run between 12.0V-14.4V; a typical safe threshold is 11.0V-11.5V.
• Max Temp (WVC-PRO / WVC-PRO 6 only): the temperature threshold above which IDS triggers. This row has no slider. Tap it, then swipe up or down to change it. Tap it again when you are done. Its range is 80-240 °F or 27-116 °C. The unit is set when you first open Base Settings after the display starts. If you change Temp Units later, turn the display off and on again to update this row. A typical safe threshold for car amplifiers is around 150-160 °F (65-70 °C). This appears only when the connected base station supports temperature probes.

Competition Mode

Competition Mode is for SPL contests. It turns your system down when no knob or display is connected to the base station. The LF Audio app does not count.

Option	Behavior
Off	Normal operation
Mute	With no knob or display connected, the base station sets every channel group to 0. The volume stays at 0 until you turn it back up.
Limit Vol	With no knob or display connected, the base station turns every channel group down. It goes from full volume to 0 in about 10 seconds. It stops when a knob or display connects again. The volume does not come back up by itself.

A WDD-LITE on external power stays connected while it is on. A battery-equipped unit also stays connected in Competition Mode (WDD-LITE firmware 4.12.3 or newer). See Sleep.

Remember Vol

When enabled, the base station saves the current volume level and restores it after a power cycle. When this is on:

• Max Startup Vol (slider, 0-100%, step 1%): caps the volume at startup so the system never powers on at full volume. Available on base station firmware 3.5.0 or newer.

RCA Gain

Toggles RCA output gain on or off. Each time you turn it on, the WDD-LITE shows a full-screen overvoltage warning. Tap Enable Gain to accept it, or Cancel to leave gain off. Turning it off needs no warning.

When RCA Gain is on, you set the gain for each channel:

• Each base station in your system has its own row: Unit 1, Unit 2, and so on, with its model beside it. The display shows up to 4 base stations here.
• Under it, each channel has a row: Chan 1 gain, Chan 2 gain, and so on.
• Each row goes from 0 to 63. Each step adds 0.5 dB, so 63 is +31.5 dB.
• A small preview under each channel shows its output, for example 1.78v out.

These rows need base station firmware 2.0.0 or newer. They appear once the display has read your base station's channel layout. On older base stations, one Gain Level slider sets the gain instead, with the same range and preview.

Important: Gain can drive the RCA outputs to voltages that exceed the rated input of most car amplifiers and can permanently damage equipment if set incorrectly. For the full safety warning, the gain calculator, the safe enable procedure (measuring with a multimeter, power-down ordering, and so on), and the liability disclaimer, see RCA Gain. Do not enable this feature without reading that article.

Volume Curve

Selects the curve that maps the volume knob position to output level. A live graph and a short description of the selected curve are shown.

Curve	Behavior
Natural	Logarithmic response. Most volume change at the low end, feels natural to the ear
Linear	Even response: equal volume change per step across the full range
Audio Taper	Steep response. Most of the range is concentrated in the upper portion of the knob
S-Curve	Smooth at both ends, moderate change in the middle
Competition	Very steep: minimal volume until near the top, then a rapid increase

Volume Floor

Sets the quietest level the system will output at any volume setting above zero, so the lowest usable volume stays controllable instead of dropping to near-silence. Turn Volume Floor on to enable it; when it is on, a Floor Level control appears so you can set how low it goes. The floor is stored on the base station and applies on top of whichever Volume Curve you have selected.

Clip Detection

Sets how easily the base station flags clipping. The options are Off, Low, Medium, and High. Off turns clip detection off. High is the most sensitive. For what each level catches, see Clip Detection.

Voltage Drift

A calibration offset applied to the voltage reading (range -5.0V to +5.0V, step 0.05V). Use this if the displayed voltage does not match a known-accurate voltmeter.

Live Voltage

At the bottom of Base Settings, a live Voltage row shows the current vehicle voltage as the base station reads it, updating about every half second. This lets you verify a Voltage Drift adjustment without leaving the screen.

Advanced

The Advanced screen holds firmware updates, tools for setting up your WVC system, and the reset actions. Each destructive action requires an inline confirmation.

Update Firmware

Starts an over-the-air firmware update for the WDD-LITE itself. It only installs a version newer than the one already on the device. See Firmware Updates for the full workflow.

Repair Firmware

Installs the latest published firmware even when the WDD-LITE is already up to date (a normal Update Firmware stops and reports "up to date" in that case). It uses the same WiFi and download steps as Update Firmware. Use it to repair an update that was interrupted, or firmware that is misbehaving, or when LF Audio support asks you to. See Firmware Updates.

Update Base

Sends an update request to the connected base station, which then downloads and installs its own update. See Firmware Updates.

If your system is a mesh with more than one base station, this row reads Update All Bases: a single selection updates every base station in the mesh, not just the one the WDD-LITE is connected to.

Pair WVC

Use Pair WVC to add another WVC base station to your system. Your primary base station is the one your WDD-LITE is connected to now.

First, get the new base station ready:

• A new base station needs nothing. Power it on.
• A base station that was used before must be reset. Hold its reset button for about 3 seconds, until its front light flashes. This erases that base station's settings and any knobs or displays paired to it.

Then:

1. Open Advanced and tap Pair WVC. The screen reads Pair Additional WVC.
2. Tap Start. The screen shows Scanning. It tells you to hold the reset button on the new base station. Skip this if the base station is new, or if you already reset it.
3. The display lists the devices it finds, on the Select Source list. Tap the new WVC Base Station. If it is not there, swipe right to search again.
4. Wait. The display asks your primary base station to add the new one. Then it checks that it did.

Caution: Do not press the new base station's button three times. Three quick presses only let a knob or display pair with it. Pair WVC then shows Reset Needed. Reset it instead, as above.

When it is done, the display shows one of these screens:

Screen	What it means	What to do
Connected	The new base station joined your system.	Tap Yes to link another one, or No to finish.
Update Needed	The new base station's firmware is too old to join, or the display could not read it.	Tap Retry. If it shows again, update the new base station (see WVC Firmware Updates), then tap Retry.
Not Compatible	You picked a device that is not a WVC base station.	Tap Retry, then pick the WVC Base Station.
Already Linked	You picked your primary base station.	Tap Retry, then pick the new base station.
Reset Needed	The base station you picked is not ready to join.	Hold its reset button for about 3 seconds. Then tap Retry.
Not Added	The new base station was not added.	Check that your primary base station has power. Then tap Retry. You may need to reset the new base station again first.

The display restarts at the end of every Pair WVC run. Once you tap Start, every way out restarts it: No, Cancel, a swipe right, or a long press. The screen shows Restarting for a moment. Then the display reconnects to your system. If you tap Back before Start, nothing changes and nothing restarts.

On the device list, a long press also restarts the display. A swipe right there does not. It only searches again.

To check that it worked, open Channel Groups. Each base station in your system shows as its own unit, like Unit 2: WVC-PRO.

Channel Groups

Channel Groups lets you put channels into volume groups. A group turns several channels up or down together. For example, put the front and rear speakers in one group, and give the subwoofer its own group. For more on groups, see Channel Groups and Multi-Unit Control.

The screen has these rows:

• Channel Groups sets how many groups you have, from 1 to 24. If you lower it, channels on a removed group move to Group 1.
• Under Group Names, tap a row like Group 1 Name to name that group. A keyboard opens. Names can be up to 10 characters. Tap OK to keep the name. Tap Back to leave without saving it. A group with no name shows (unnamed).
• Each Group row (Group 1, Group 2, and so on) is Standalone, or follows another group. The choices read "Relative to 2" and so on, or "Rel to" and the group's name if you named it.
• Each base station shows as its own unit, like Unit 1: WVC-PRO. The screen lists up to 8 base stations. Under each one, each Channel row picks that channel's group. With only one group, these rows cannot change. Set Channel Groups to 2 or more first.

Your changes save to the base station when you leave the screen. It does not matter how you leave: tap Back, tap the title, swipe right, or long-press.

• The display must be connected to the base station when you leave. If it is not, your changes are not saved.
• If a warning or an update takes over the screen while you edit, your changes are not saved. Open Channel Groups and make them again.
• A group with no channels in it is removed when you save.
• With a lot of groups, long names may be cut a little shorter so they all fit.
• The screen shows Updating... until the display has read your setup. It fills in by itself.

Pair Knob

Use Pair Knob to add another knob to your system. It puts your WVC base station into pairing mode for the new knob. The screens walk you through it:

1. Pair Additional Knob: tap Start. Tap Back to leave without changing anything.
2. Base Station Ready: the base station's light should now blink. Tap Next.
3. Power On Knob: power on the new knob. On that knob, open the Advanced menu and do a factory reset. Then tap Next.
4. Waiting: when the new knob shows its main screen, tap Done.
5. Complete: tap Continue.

The display cannot see the new knob join. So check the knob itself before you tap Done.

A swipe right or a long press works like Back before Start. After Start, it works like Cancel. On the Complete and Cancelled screens, it works like Continue. If you cancel after Start, the screen shows Cancelled. The base station stays in pairing mode. Turn the base station off and on again to end it.

Smart Home

Shows your base station's Home Mode and smart home state, and lets you change them. Home Mode connects the base station to your home WiFi so smart home apps can control it. For setup, see Smart Home Integration.

The rows you see depend on the current state:

Row	What it shows or does
Home WiFi	The Home Mode state: Off, Connecting..., Connected, Reconnecting..., or Failed. Tap it to turn Home Mode on or off.
Issue	Why Home Mode failed: Set WiFi in app, Network not found, Wrong password, Connection timed out, or Unknown. Shown only after a failure.
Retry	Tries the Home WiFi connection again. Shown only after a failure.
Smart Home	The smart home state: Not available, Not set up, Pairing..., Pairing failed, Re-pair needed, or the name of your home once it is set up (Paired if there is no name).
Pairing Code	The code to type into your smart home app. Shown while the base station waits to be set up.
Info	Reads Groups changed when your channel groups changed after setup.
Re-pair	Removes the current smart home setup so you can add the base station again. Shown with Groups changed.
Decommission	Removes the base station from your smart home. You can set it up again later. Shown once it is set up.

Each action opens a screen with Confirm and Cancel. Confirm ignores a tap right after the screen opens. Wait a moment, then tap it. After Confirm, a spinner shows. The screen goes back when the base station shows the change, or after about 8 seconds. The screen also says Tap to cancel. A tap only takes you back sooner. It does not undo the change, which was already sent.

Forget Phones

Use Forget Phones when your phone cannot pair with your base station. It removes every phone paired to the base station. You do not need a phone to use it.

1. Open Advanced and tap Forget Phones.
2. The screen asks: "Remove every phone paired to your base station? Each phone must pair again with the BT Pin."
3. Tap Forget. It ignores a tap right after the screen opens. Wait a moment, then tap it.
4. The screen shows "Removing phones..." This can take up to about 12 seconds. The screen does not respond to touch until it is done.
5. Read the result, such as Phones removed or No response. See What the result means.
6. Tap OK to go back. Like Forget, it ignores a tap right after it shows.

To stop, tap Cancel instead of Forget. A swipe right or a long press does the same. Nothing is removed.

Then do this on each phone:

1. Open your phone's Bluetooth settings. Forget your base station, analyzer or hub there.
2. Close the LF Audio app fully. Then open it again.
3. Let the app find your base station, analyzer or hub. Pair again.
4. Enter the BT Pin when your phone asks. With a WVC base station, find it in Base Info. With an analyzer or hub, read it on its own touchscreen. Open Settings > System tab. Find BT PIN.

Good to know:

• It removes every phone, not just one. Each phone must pair again.
• Your knobs and displays stay paired. The BT Pin does not change.
• Do you link more than one base station? It clears only the one your WDD-LITE is paired with. The others keep their phones.
• A phone with the LF Audio app may pair again by itself. This is normal. Forget Phones is for a phone that cannot pair. It does not keep out someone who knows the BT Pin.

For the full guide, see Forget Phones.

Forget Base

Clears the stored pairing and restarts the WDD-LITE, bringing back the getting-started wizard so you can pair a different base station. Your display preferences, color theme, and saved WiFi networks are kept.

Tap Forget Base. Two choices show right away: Confirm Forget and Cancel. Cancel is highlighted first. Tap Confirm Forget to go ahead, or Cancel to go back. Confirm Forget ignores a tap right after it appears, so wait a moment first.

Factory Reset

Clears all stored settings, display preferences, color theme, and pairing, then restarts the WDD-LITE into the getting-started wizard.

Tap Factory Reset. Two choices show right away: Confirm Reset and Cancel. Cancel is highlighted first. Tap Confirm Reset to go ahead, or Cancel to go back. Confirm Reset ignores a tap right after it appears, so wait a moment first.

Battery

Battery-equipped units only. This screen shows the current charge level as a large reading with the battery voltage beneath it, over a trend graph of the battery voltage so you can see how it has been discharging. While the display is plugged in it shows Charging in place of the charge percentage, because the charger holds the battery voltage up and a percentage read at that moment would be optimistic. A Back item returns you to the menu.

On these units the top bar also carries a battery icon with the charge level next to the signal-strength meter, which changes to a charging symbol while the display is plugged in. A standard WDD-LITE has neither the Battery menu item nor the top-bar battery indicator.
