6. Maintenance

• Cleaning: Use a soft, damp cloth to clean the display and casing. Avoid abrasive cleaners or solvents that could damage the plastic.
• Inspection: Periodically check all wiring connections to ensure they are secure and free from corrosion. Inspect the speed sensor for any damage or misalignment.
• Water Resistance: The unit is designed to be waterproof and shock-resistant. However, avoid prolonged submersion or high-pressure water jets directly on the unit.

7. Troubleshooting

• No Power: Check the power connections (Black wire for positive, Green wire for negative/ground) and ensure the motorcycle's ignition is on. Verify the battery voltage.
• Inaccurate Speed/RPM: Ensure the speed sensor is correctly installed and aligned. Check the RPM signal wire connection (Black-Yellow). For cylinder settings, refer to the specific instructions provided with the product for calibration.
• Display Issues (e.g., no backlight, flickering): Check all wiring connections. If the backlight is not working, try adjusting the color as per section 5.3.
• Moisture Inside Display: While designed to be waterproof, extreme temperature changes or prolonged exposure to high humidity can sometimes cause condensation. If this occurs, ensure all seals are intact and allow the unit to dry in a warm, dry environment. If the issue persists, contact support.
