How-to Guides

The LY 810 display combines riding information, drive controls, Bluetooth connectivity, NFC access, and password-start options in one instrument. If your BOYUEDA scooter uses this display, learning the controls before riding makes it easier to check speed, mileage, battery-related indicators, riding mode, and warning messages without guessing. This guide follows the functions listed in the official LY 810 Display Manual and explains what each control is intended to do, how to approach the settings menu, and what to do when a fault code appears.

The official manual currently identifies the LY 810 display as applicable to BOYUEDA M2, S5, and Q7 Pro Max (the page uses the model label S5-11). It is provided for reference, and the page notes that display information may change with product upgrades. Confirm that your scooter has the LY 810 instrument before following these steps. The LY 810 controls are not interchangeable with TF100 instructions.

1. Know the Main Display Areas

The LY 810 screen presents speed, a gear indicator, riding-mode labels, battery-related graphics, status icons, and a multifunction area. Depending on the selected screen, the multifunction area can show ODO, TRIP, TIME, fault information marked E, or voltage marked V. The top icons include symbols associated with the headlight, Bluetooth, cruise control, NFC, and a warning state. Use the labels and icons on your own display as the reference; the exact screen appearance can differ after a product upgrade.

Speed and gear

The central numeric area displays riding speed, with the selected unit shown as km/h or mph depending on the unit setting. The gear indicator shows the currently selected gear. The screen also includes riding-mode labels such as SPORT, COMFORT, ECO, and PRO. Do not assume that every configuration exposes every mode in the same way; check the labels and controls on your scooter.

ODO, TRIP, TIME, voltage, and fault screen

ODO is the accumulated odometer reading. TRIP refers to trip distance, while TIME is the running-time display. The V interface displays voltage information. The E interface is used to view fault status when the warning symbol flashes. Before contacting support, note the exact code and take a clear photo of the screen. Switching screens can make a warning easier to identify, but it does not repair the underlying issue.

Status icons

The manual identifies Bluetooth and NFC functionality, including password boot. The headlight icon indicates lighting status, and the warning icon alerts the rider to a fault state. Start-mode labels distinguish the selected start behavior. Because these indicators are linked to different settings, learn their meaning while the scooter is stationary instead of trying to interpret them while moving.

2. Button Functions

The button numbers are the names used in the official manual. The instrument graphic also labels the buttons with markings such as 1, 2, MODE 3, F/B 4, and D 5. On some scooters, the printed labels or button arrangement may look slightly different. If the controls on your unit do not match, stop and confirm the display version before trying combinations.

Make changes while parked. A button press can change the headlight, start behavior, drive mode, or speed-limit screen. Do not navigate the display menu while riding, and do not change a setting unless you understand its purpose and have confirmed the correct value for your exact scooter configuration.

3. Bluetooth and My-Trip App Connection

The official LY 810 manual states that the instrument has Bluetooth functionality and directs users to the My-Trip app. For Android, the page provides an app download link; for iPhone, it says to search the App Store for “My-Trip.” Open the app, tap the Bluetooth icon, and search for a Bluetooth name beginning with “LIVIAE.” Select the matching device and follow the app’s login flow. The manual says registration is required to modify parameters, helping prevent unauthorized changes.

Do not assume a Bluetooth symbol means every function is available on every phone or scooter configuration. If the scooter does not appear, confirm that the display is powered on, Bluetooth is enabled on the phone, the app is the version recommended by the official page, and the scooter is within range. Close and reopen the app if necessary. Avoid pairing with an unfamiliar device name, and do not use third-party apps or unverified firmware to change scooter parameters.

4. NFC Cards and Password Start

The LY 810 manual describes three factory cards: one blue main card and two white secondary cards (the page says three cards are supplied, describing blue as the main card and white as secondary cards). The blue card acts as the master card for pairing new secondary cards; it is not used to start the scooter itself. White secondary cards are used for starting. If a white card is lost, the blue main card is required to pair a replacement.

Using NFC to start

When the start mode requires an NFC card, briefly press the power button. The display shows the letter N. Swipe the card over the designated area marked “NFC.” Keep the card close to the marked area and wait for the instrument to respond. If the scooter does not start, check the selected start mode and use the correct card; do not repeatedly change background parameters to bypass the lock.

P95 start modes

If you change the default password, store the new password somewhere secure. If you forget it, consult BOYUEDA support for the model-specific recovery procedure rather than repeatedly entering guesses or resetting unrelated parameters.

5. Pairing a New NFC Secondary Card

The official page describes this pairing sequence: briefly press the boot button and, within 5 seconds, swipe the blue main card in the NFC area. When the display prompts for a secondary card and numbers 1, 2, or 3 appear, swipe the white secondary card to be paired. Follow the display prompts for the cards you are registering. Keep the master card available because it is required to add a replacement secondary card.

Only perform card pairing while the scooter is stationary and powered in the required state. If the instrument does not show the expected prompt, stop and review the official procedure. Do not assume that a card from another scooter can be paired, and do not discard the blue main card after setup.

6. Background Settings: Use Care

The manual calls the background parameters complex and says they are generally not required for normal use. It recommends using the My-Trip app to reduce the risk of incorrect settings. Buttons 3 and 5 enter the background settings. The parameter list below summarizes the labels and ranges stated on the official page; it is not a recommendation to modify them.

The parameter names above follow the official page, including its terminology. Some settings affect voltage interpretation, speed calculation, drive behavior, braking, and startup response. Do not change voltage level, wheel size, magnet count, motor drive percentage, electronic braking, or speed-limit settings unless BOYUEDA confirms the correct values for your scooter. A wrong setting can cause incorrect readings or unexpected behavior.

The manual also describes ODO zero clearing: on the ODO interface, briefly press Button 3, then hold it for 5–6 seconds until the digits clear. This removes the displayed accumulated-distance value. Do not use this procedure casually; record the mileage first if you need it for maintenance, resale, or warranty discussions.

7. Fault Codes and First Checks

When the warning symbol flashes, the manual says to press the M/3 key to switch to the E interface. The number displayed identifies the fault category. Record the exact code before switching screens or turning the scooter off.

These labels identify fault categories; they do not prove which individual part must be replaced. If the display reports a brake fault, controller fault, voltage fault, or communication fault, stop riding if the scooter behaves abnormally. Do not open the battery pack or controller housing, disconnect live wiring, or bridge connector pins as a test. Photograph the code and contact BOYUEDA support with your model, display type, and a description of what happened.

The wiring section on the official page lists red D+ as positive power input, black GND as power negative, blue DS as the controller switch lock, green Tx as communication transmission, and yellow Rx as communication reception. It also includes a Hall signal connection. These descriptions are for identification only; do not use them as permission to probe or reconnect wires without the correct wiring diagram and technical experience.

8. Common Questions

Which scooters use the LY 810 display?

The official manual currently names BOYUEDA M2, S5, and Q7 Pro Max. The page uses S5-11 as the model label. Check the display installed on your scooter before using this guide.

Can I use the TF100 instructions for the LY 810?

No. The TF100 is a different display with different buttons, menus, and documented fault codes. Follow the guide for the instrument actually installed on your scooter.

Why does the scooter ask for an NFC card or password?

The P95 setting controls startup access. The manual lists 0 for no password/NFC, 1 for NFC-only, and 2 for password or NFC. Check the current setting and use the correct credential.

What should I do if the My-Trip app cannot find the scooter?

Confirm that the display has Bluetooth, the phone has Bluetooth enabled, and the app is searching for a device name beginning with LIVIAE. Check the official app instructions and avoid changing display parameters just to force a connection.

Can I reset all display parameters?

The official page lists P99 as one-key recovery and says to long-press Button 3 for 5–6 seconds to reset all parameters. This may alter scooter settings, so do not use it as a first troubleshooting step. Contact support if you are unsure of the correct configuration.

What should I do if a fault code returns?

Record the code and symptoms, stop riding if braking or motor control is affected, and contact BOYUEDA support. Do not assume a code identifies a single replaceable part.

Before Your Next Ride

Before riding, check that the display starts normally, the selected unit and gear are understood, the headlight works when required, and the brakes respond correctly. Confirm that the start mode is appropriate and that the scooter does not show an unresolved warning. Learn how to reach ODO, TRIP, TIME, voltage, and fault information while parked. If the screen or menu differs from the images in this guide, use the manual for your display version instead of trying unfamiliar button combinations.

For model-specific help, refer to the official LY 810 Display Manual and the owner’s manual for your scooter. The LY 810 manual notes that product upgrades can change display information without affecting normal use. If a setting, icon, or procedure does not match your unit, take a photo and ask BOYUEDA support to confirm the correct instructions before changing parameters.
