Product Usage Instructions

Display Installation

1. Open the clamps of the display and insert the rubber rings on the inside of the clamps.
2. Open the clamp on the D-pad and place it in the correct position on the handlebar. Use an M3*12 screw to tighten the D-pad onto the handlebar with a torque requirement of 1N.m.
3. Place the display onto the handlebar in the correct position. Use two M3*12 screws to tighten the display into position with a torque requirement of 1N.m.
4. Link the display to the EB-BUS cable.

Normal Operation

Switching the System ON/OFF
To turn on the system, press and hold the system ON button (>2S) on the display. Press and hold the same button again (>2S) to turn off the system. If the automatic shutdown time is set to 5 minutes, the display will automatically turn off within the desired time when not in operation. If the password function is enabled, you must enter the correct password to use the system.
