- Clock adjustment
In normal display mode, press and hold the ADJ key to turn on the display, and the minute digit will flash. At this time, each short press of the ADJ key will increase the minute value by 1, and long press of the ADJ key will continuously increase the minute value until the key is released. After adjusting the minutes, short press the SET key, and the hour digit will flash. At this time, each short press of the ADJ key will increase the hour value by 1, and long press of the ADJ key will continuously increase the hour value until the key is released. After completing the setting, save the parameter setting and exit. - Metric and imperial System Switching
In normal display mode, press and hold the SET key for 10 seconds, and the speed unit will switch from KPH to MPH. To switch back, press and hold the SET key again for another 10 seconds. - Reset the subtotal TRIP value
In normal display mode, press and hold the ADJ key for 3 seconds, the subtotal TRIP value will be reset - Reset the total TRIP value
Press and hold the SET key to turn on the display, enter the password operation interface, at this time the screen displays P-0000, the rightmost digit is selected, and it flashes at a frequency of 1Hz. In this interface, short press the SET key will increase the number on the selected digit by 1, and the value of the number on the digit will cycle between 0 and 9; Long press the SET key will select the digit one place higher. After the 4-digit number is entered, if the value is 8810, the global TRIP value will be reset; if the value is 6810, the setting interface will be entered; if the value is other, it will return to the password operation interface and display P-0000. - Brightness Adjustment
Can’t be adjusted , the backlights always have same brightness. - Adjust the parameters of speedometer
All the following screen adjustments are for the speedometer section only and are unrelated to other sections. The upper computer is set to use MPH as the speed unit, and KPH is used as the speed unit in the text document modification. If the speed or mileage 60KPH frequency is not modified during the modification, it will maintain the last set value. If the speed or mileage 60KPH frequency is modified, it will be switched to the corresponding metric speedometer.
Press and hold the SET key to open the display and enter the password operation interface. At this time, the screen displays P-0000, and the rightmost digit is selected and flashes at a frequency of 1Hz. In this interface, short press the SET key will increase the number on the selected digit by 1, and the value of the number on the digit will cycle between 0 and 9; long press the SET key will select the digit one place higher. After the 4-digit number is entered, if the value is 6610, the vehicle speed ratio setting interface will be entered; if the value is 8810, the cumulative value will be cleared; if the value is 6810, the cumulative setting interface will be entered; if it is other values, it will return to the password operation interface and display P-0000.

When entering the parameter setting interface, the screen will statically display 0-0420. In this state, short press the SET key to advance to the next parameter 1-0420. Long press the SET key to enter the value modification mode. At this time, the rightmost digit is selected, and it flashes at 1Hz. Short press the SET key to select the digit and add 1 to the digit value, which cycles between 0 and 9. Long press the SET key to select the higher digit. After the highest digit is set, long press the SET key to exit “0” and complete the setting. Then the screen will statically display 0-0420. Short press the SET key to switch to 1-0420 and set it, and so on. During the battery judgment time, if the voltage changes exceed the set value of the battery change rate, the pointer will update to the new value after the time is greater than the maximum time, otherwise the current position will be maintained. If the voltage change is less than the set value of the battery change rate, the pointer will be updated directly to the new value. Pressing the SET key again in the J-0030 interface will exit the entire setting operation. The instrument will automatically run according to the new parameters.
If you only need to modify the speed ratio, after the speed ratio is modified, when you jump to the 1-0420 interface, turn off the instrument and then restart it. The instrument will run using the new parameters.
