4.3 Function interface introduction
Boot interface and basic function interface
Boot logo interface is displayed for 3 seconds after display is turned on. When the
communication connection is established, display enters the main interface, showing real-time
information stored in the controller and battery BMS according to the communication protocol.
(Battery indicator will not show battery percentage if BMS info is not available)
Basic interface includes real-time speed info, battery info, PAS indication, real-time clock，
light-on indication, Bluetooth connection and riding data analysis.
Riding data analysis displays speed info and trip info which includes TRIP, ODO, Range, Average
speed, Max speed and trip time. Speed display value has 3 digits, maximum value is 99.9KM/H,
including one digit after the decimal point. ODO value has 4 digits, with one digit after decimal point.
After 9999.9 KM is exceeded, the decimal point is not indicated, and a 5-digit mileage value is
displayed directly, with a maximum value of 99999km. After the maximum value is exceeded, the
value is shown as the actual mileage value deducted by 100,000.
