6. Operation and Programming
The speedometer features three buttons for operation and programming. Press and hold the 'Mode' button for 3-5 seconds to enter programming mode.
6.1 Odometer Functions
- Total Mileage: The total mileage is programmable.
- Trip Counter: The device includes a trip odometer that can be reset to zero.
6.2 Setting Total Mileage (0-999999.9 km)
- Press and hold the 'Mode' button for 3-5 seconds to enter setting mode.
- The display will show a value (e.g., "6.2" as a placeholder for current total mileage).
- Press the 'Mode' button to cycle through the digits you wish to change.
- Press the 'Set' button to change the value of the selected digit.
- After setting the desired total mileage, press the 'Mode' button again to save the setting and exit.
6.3 Setting Speed Ratio (1000-65535 pulse/km)
The speed ratio (pulses per kilometer) is programmable, allowing compatibility with various truck models and speed sensors.
- Press and hold the 'Mode' button for 3-5 seconds to enter setting mode.
- The display will initially show a value (e.g., "6.2"). Continue pressing the 'Mode' button until the display shows the current speed ratio value (e.g., "2470").
- Press the 'Mode' button to cycle through the digits.

| Dambudziko | Zvinogona Kukonzera | Solution |
|---|---|---|
| No display/Power | Hapana magetsi; Waya dzisina kururama; Fuse yakaputika | Check power connections (+9~36VDC and GND). Verify wiring according to diagram. Check vehicle fuse. |
| Incorrect speed reading | Incorrect speed ratio setting; Faulty speed sensor; Loose signal connection | Recalibrate the speed ratio (Section 6.3). Inspect speed sensor and signal wire. |
| Odometer not updating | No speed signal; Incorrect wiring | Check speed sensor and signal connection. Ensure Pin 1 of the yellow connector is correctly wired. |
| Buzzer alarm not working | Overspeed alarm value not set; Faulty internal buzzer | Set the overspeed buzzer alarm value (Section 6.4). If still not working, contact support. |
9. Mazano emushandisi
- Kuenderana Kuongorora: Usati watengaasing or installing, verify compatibility with your vehicle's existing speed sensor type (Inductive & Hall Effect) and electrical system (9-36VDC). For specific vehicle models like a Scania 113 (1995, 6-speed gearbox), ensure the sensor output matches the speedometer's input requirements.
- Kuenzanisa kwakarurama: Take time to accurately calibrate the speed ratio (pulse/km) for precise speed and mileage readings. Refer to your vehicle's specifications or a GPS device for accurate speed verification during calibration.
- Backlight Wiring: Connect the backlight wire (Pin 3 of the white connector) to a switched 9-36VDC source that activates with your vehicle's lights for optimal night visibility.
