Display of Power-Assist

#### Battery Capacity Indicator

The KT-LCD3 can identify 24V, 36V, 48V battery capacities when used with supporting controllers. When the battery capacity is over 70%, four bars from the battery indicator will be displayed. As the battery capacities drop, the bars will change accordingly. Once the power capacity is less than 15%, the battery indicator will be empty and show zero bars. If the power display frame flashes, it is due to voltage shortage where the controller will power off.


#### PAS Ratio



Press button or button to adjust the power assist ratio, changing the motor output power. Range of power assist is between 1 and 5 (this can also be configured according to the rider’s requirements), where one provides the lowest power and five provides the highest. When the PAS ratio is set to zero, the power assist function is off.

#### Power Push Function


Users can use power push function for assistance in vehicle take-off. Hold button and the motor will provide power until vehicle reaches 6 Km/H. The meter assist function icon will flash indicating the function is active. By releasing the button, the function will be revoked.
