5. Maintenance

Proper maintenance ensures the longevity and reliable performance of your QS-S4 unit:

• Cleaning: Wipe the display and unit with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the plastic or screen.
• Inspection: Periodically check the mounting screws to ensure they remain tight. Inspect the cable and connector for any signs of wear, fraying, or damage.
• Environmental Protection: While the unit is made of high-strength material, avoid prolonged exposure to extreme weather conditions (heavy rain, direct sunlight for extended periods) to prevent potential damage.
• Storage: If storing the scooter for an extended period, ensure the unit is clean and dry.

6. Troubleshooting

If you encounter issues with your QS-S4 display and throttle, consider the following common troubleshooting steps:

• Display Not Turning On:
  • Ensure the 6-PIN connector is fully seated and secure.
  • Check the scooter's main power supply and battery charge.
  • Verify the power button is being pressed correctly and held for sufficient duration.
• Throttle Not Responding:
  • Confirm the display is powered on.
  • Check the 6-PIN connection for looseness or damage.
  • Ensure there are no obstructions preventing the thumb throttle from moving freely.
• Inaccurate Readings:
  • If speed or distance readings seem incorrect, ensure the wheel size setting (if adjustable in advanced settings) matches your scooter's wheel size.
  • Minor variations in color or appearance due to manufacturing batches do not affect functionality.
• Error Codes:
  • If an error code appears on the display, consult your scooter's main user manual or contact the scooter manufacturer for specific code definitions and solutions.

If problems persist after following these steps, it is recommended to contact the manufacturer or a qualified technician for further assistance.
