KEY DEFINITION

NORMAL OPERATION

Switching the System ON/OFF
Press and hold (>2S) to power on the display, the HMI begin to show the boot up LOGO. Press and hold (>2S) again can power off the HMI.

If the “automatic shutdown” time is set to 5 minutes (it can be set in function “Auto Off”), the HMI will be automatically turned off within this set time, When it is not operated.

Note: if the controller has Boost function, can be selected this level with briefly press .

Selection Mode
Briefly press button to view the different mode and information.

1. System with torque sensor, circularly show single trip distance (TRIP,km) → total distance (ODO,km)
   → maximum speed (MAX,km/h) → average speed (AVG,km/h) → remaining distance (RANGE,km)
   → energy consumption (CALORIES/CAL,KCal) → real-time output power (POWER,w) → riding time (TIME,min).

2. If system with a speed sensor, circularly show single trip distance (Trip,km) → total distance (ODO,km) → maximum speed (MAX,km/h) → average speed (AVG,km/h) → remaining distance (RANGE,km) → riding time (TIME,min)
