Operating Instructions
Basic Operation
Once properly installed and wired, the instrument will power on with your motorcycle's ignition. The display will show current speed, RPM, odometer, and other indicators.
Display Functions
- Speed: Digital display of current speed in km/h or mph.
- RPM: Analog needle display for engine revolutions per minute.
- Odometer (ODO): Total accumulated distance.
- Trip Meter (TRIP): Resettable distance for individual trips.
- Gear Indicator: Displays current gear (1-6) and Neutral (N).
- Fuel Level: LED indicator for fuel tank level, with low fuel warning.
- Indicators: Left/Right turn signals, High Beam, Engine Check, Battery Voltage.
- Clock: Time display.
Setting Adjustments
The instrument features a button (referred to as KI/K1 and K2 in some instructions) for navigating and adjusting settings. The following adjustments can be made:
- Entering Settings: On the TRIP page, long press the KI button to enter the settings menu. The password is 888.
- Wheel Circumference (ID-OOO): Long press KI to edit tire circumference (initial setting 180 cm). While the first digit blinks, short press K2 to edit the digit. Short press KI to move to the next digit (second or third). This setting adjusts speed accuracy based on your tire size.

Troubleshooting
If you encounter issues with your Geloo instrument, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Instrument does not power on | No power supply; loose wiring connection; blown fuse. | Check power wiring, ensure secure connections, inspect and replace fuses if necessary. |
| Speed reading is inaccurate or not displayed | Speed sensor not installed correctly; magnets not detected; incorrect wheel circumference setting. | Verify speed sensor installation and magnet placement. Adjust wheel circumference and pulse settings in the menu. |
| RPM needle does not move | RPM signal wire not connected or incorrect connection; engine stroke setting incorrect. | Check RPM signal wire connection according to the wiring diagram. Verify FACTOR engine stroke setting. |
| Backlight color cannot be changed | Incorrect mode for adjustment. | Ensure the instrument is in ODO mode when attempting to change backlight colors. |
