Rotate the handlebar under normal operating of the meter, the display interface shows
the sign of turned-on handlebar, see the Figure below. The sign will be off automatically
after about five seconds.
○Display of power-assist startup
The meter is driving with power-assist under normal operating conditions, the display
interface flashes the power-assist startup sign (ASSIST) as shown in the figure. The sign
will be off automatically after about five seconds.
○PAS Ratio (or Handlebar) Gear Switch
Under normal operation, press button (UP) or button (DOWN) to
switch the power assist ratio (or handlebar) gear (PAS), changing motor output power.

At every startup, the meter will automatically restore gear (this can also be
configured as required by users) when it was at last shut down. When the power
assist ratio is gear 0 zero, there’s no power assist function.
○Power Assistant Push Function
Users can use 6Km/H power assist function when pushing vehicles. Hold
button (DOWN), the meter assist function logo ( ) flashes, the vehicle drives at the
speed of no more than 6Km/h. Release button (DOWN), the assist function will be
revoked.
○Cruise Function
When C7 parameter setting is 1 (see C parameter setting), the meter turns on cruise
function, hold button (DOWN) long to enter the cruise status when the vehicle
speed is more than 7 km/h, and the cruise function logo (CRUISE) lights. Brake or hold
any button to revoke cruise function.

○ Startup Backlights and Headlights
Hold button (UP) long, the meter turns on the backlights as well as the vehicle
headlights (the Controller should have headlights driving and output functions), meter
backlighting and vehicle lights power logo ( ) light, hold button (UP) long again
to turn off backlights and vehicle headlights.
○Battery Capacity Indicator
The meter can automatically identify 24V, 36V, 48V battery capacities when it is
supporting use with the specified controller. When the battery capacity is over 70%, the
four power displays of the meter are lit, when the battery capacities drop, the four power
displays are off in order, when the power capacity is less than 15%, the four power
displays are totally turned off.
When the controller is power off due to voltage shortage, the power display frame
flashes, indicating the vehicle has been in voltage shortage and waiting for shutdown
currently.

○Motor Operating Power and Temperature
Under the riding status of vehicle, the real time running and output power can be
known via the meter displays.
Motor operating power
The operating temperature of the motor shows there should be a temperature
sensor installed in the Inner motor to output the temperature for signal detection
simultaneously.
Motor operating temperature
When the motor operating temperature exceeds the warning value, temperature
display flashes to alarm, meanwhile the motor controller will offer the appropriate
protection to motor.

○ Environment Temperature
After startup, the environment temperature for using meter will be displayed in
environment temperature display column.
Environment temperature display
The temperature display value may be in deviation shortly after boot-up, and the
display value will be gradually approaching the environment temperature within 10
minutes after boot-up.
○Single Data Clearing
5 seconds after the meter is powered on, at display 1, hold both the button (UP)
and the button (DOWN) simultaneously for about 2 seconds, the single trip time
(TM) and single trip distance (DST) flicker, then hold button shortly (SW), the
record contents of both will be cleared.
Single data clearing display
Under the status of data flashing, if there were no operations on the data within 5
seconds, the meter will automatically return to display1 after 5 seconds, and the
