• Switching Display Modes: Press the MODE button to cycle through different display functions (e.g., current speed, average speed, trip distance, total distance, clock, temperature).
• Backlight Activation: The backlight can be activated automatically in low light conditions or manually by pressing a specific button (refer to the detailed instructions in the included paper manual for specific button press combinations).

6. Settings

To access settings, typically a long press of the SET button is required. Use the MODE button to change values and the SET button to confirm.

6.1. Time Zone Setting

Set the correct time zone for your region. For Japan, the time zone is typically set to '09'.

6.2. Speed Unit Setting

You can choose between kilometers per hour (KM/H) or miles per hour (M/H) as your preferred speed unit.

6.3. Odometer (Total Distance) Setting

The total distance can be manually adjusted or reset. This is useful if you are transferring the computer to a new bike or wish to correct the total mileage.

7. Maintenance

• Cleaning: Wipe the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Battery Replacement: When the battery indicator shows low power, replace both CR2032 batteries. Ensure correct polarity.
• Sensor and Magnet Check: Periodically check the sensor and magnet for proper alignment and secure attachment. Ensure the gap remains within 1.5mm.

8. Troubleshooting

• No Speed Reading: Check the sensor and magnet alignment. Ensure the gap is less than 1.5mm. Verify the sensor cable is securely connected to the main unit.
• Inaccurate Readings: Recheck the wheel circumference setting in the device settings. Ensure the sensor and magnet are stable and not moving during rides.
• Display Not Working: Check battery levels and replace if necessary. Ensure the unit is properly seated in its mount.
• Buttons Unresponsive: Ensure the buttons are not stuck. If the issue persists, try removing and reinserting the batteries to perform a soft reset.
• Water Ingress: While designed to be waterproof, extreme conditions or prolonged exposure to heavy rain may cause issues. If water enters the unit, remove batteries and allow it to dry completely before re-use.
