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.

7.7.2 Selection of Support Levels
When HMI power on, briefly pressor to select the assistance level (the number of assistancelevel needs to be adapted to controller), The lowest level is Level 0, the highest Level is 5. On thedefault is Level 1, “0”means no power assistance. The interface is as following:

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

7.7.3 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).
