button.)
The vibration motor vibrates for 0.5 seconds, the indicator light turns off, and the device
shuts down.
Connected
No buttons were pressed for 15 minutes. (The timer resets if a button is pressed).
The vibration motor vibrates for 0.5 seconds, the indicator light turns off, and the device
shuts down.
4. Upshift Key
After pressing, the vehicle gear shifts up one position.
Continue pressing to increase the vehicle gear by one every second.
You can still shift up or down gears while pushing the gearshift.
When you control the vehicle with the gear shift button, it enters linear calibration mode.
5.
Back/Slow Down Key
If the vehicle is in forward position:
Press to decrease the gear by one;
Press and hold to decrease the vehicle gear by one every second.
Until the gear is set to 0th;
You can still shift up or down gears while pushing the gearshift.
When pushing the handlebar and shifting down gear with the remote control, the vehicle
enters a linear calibration mode.
If the vehicle is stationary;
Press the button to reverse the vehicle; release it to stop reversing.
Control the vehicle using the back/accelerate buttons, and it will enter linear correction mode.
6. Turn Left/Right
The vehicle starts turning left and right when the button is pressed, and stops turning when
released.
You cannot use the left/right turn buttons when reversing.
When pushing the vehicle, use the left/right turn buttons; after turning, the vehicle will enter
linear correction mode.
7. distance
Press to drive 10 m; release and press again to increase the distance by 10 m. Repeated
presses will not increase the distance.
The distance control button can be used during parking, pushing, or remote operation.
When pushing the device, use the distance-setting button to maintain linear alignment.
8. Spacebar
Pressing this button switches the vehicle to neutral/parking mode.
Press and hold for 3 seconds to pair the remote control.
9.
Pairing and Connecting
Enter pairing mode:
Press and hold the spacebar for 3 seconds to enter pairing mode on the remote control.
When entering pairing, all indicator lights remain illuminated and the vibration motor
vibrates for 0.5 seconds.
If the remote control is already connected to the vehicle at this time, entering pairing will
disconnect it from other remotes.
Unpair:
Press any key except the Lock/Unlock keys to exit.
Exit automatically in 5 minutes;
If pairing fails, the remote control will not delete the pairing information.
Unpair and vibrate the motor for 2 seconds;
Pairing successful:
Vibrate for 0.5 seconds, automatically disconnect from pairing, and connect to the paired
vehicle while deleting other pairing information.
10. Connect and disconnect
After turning on, the remote control continuously scans to verify if a paired vehicle is
powered on. If so, it automatically initiates connection.
Connection successful:
Vibrate the motor for 1 second;
disconnect ：
Vibrate the motor for 3 seconds;
11. charge
When charging begins at the Type-C port, the vibration motor will shake immediately for 0.5
seconds.
When the Type-C port stops charging, the vibration motor will immediately vibrate for 0.5
seconds and then shut down.
Charging status:
BLE connection has been severed; buttons are malfunctioning.
The indicator light will flash or remain on continuously depending on the charging status.

IV. Core Technical Parameters
1. Communication Protocol: 2.4G
2. Communication range: Controllable distance in open environments ≥50 meters
3. Operating frequency band: 2.4 GHz, a universal ISM band with strong anti-interference
capability
4. Response Latency: Low-latency transmission ensures smooth real-time control without lag
5. Indication method: Three-color LED status indicator (red/yellow/green) with vibration
motor feedback
6. Operating Temperature: -10°C to +60°C
V. Common Fault Diagnosis
1. The remote control is unresponsive and cannot operate the vehicle: Check the device's
battery level, restart the remote control, and repair the pairing; investigate whether there is
strong electromagnetic interference in the vicinity, and try again after moving away from the
source of interference.
2. The indicator light remains red and vibrates frequently as an alarm: The device has low
battery; replace the battery promptly. If Bluetooth connection is lost, repair the device pairing.
3. Slow response or excessive latency: Reduce the distance between the remote control and
the vehicle, eliminate surrounding 2.4 GHz interference sources, and repair the connection.
4. No effect when switching gears: Restart the remote control and the vehicle, re-establish
communication, and try again.
