powered-off together with that of the controller.
○Display of turned on handlebar
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.
○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.
Switching range is 0-5 gear (this can also be configured according to the customer
requirements), gear 1 is for the lowest power, and gear 5 is for the highest 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 ( ) lights. Brake or hold any
button to revoke cruise function.
○ Startup Backlights and Headlights
