5. Maintenance

• SD Card Management: Regularly format the SD card (at least once a month) to ensure optimal performance and prevent data corruption. Replace the SD card if it shows signs of wear or frequent errors.
• Lens Cleaning: Keep the front and rear camera lenses clean using a soft, lint-free cloth to ensure clear video quality. Avoid abrasive materials that could scratch the lens.
• Cable Connections: Periodically check all cable connections to ensure they are secure and free from damage. Loose connections can lead to intermittent power or recording issues.
• Temperature Considerations: The dash cam is designed to operate in temperatures from 4°F to 158°F (-20°C to 70°C) thanks to its supercapacitor. Avoid exposing the device to extreme temperatures outside this range for prolonged periods.

6. Troubleshooting

• Recording Stops Intermittently:
  • Ensure your SD card is a Class 10 U3 speed or above. Lower speed cards may not keep up with the data rate.
  • Format the SD card regularly within the dash cam's settings or via the app.
  • The SD card may be faulty; try replacing it with a new, high-quality card.
• WiFi Connection Issues:
  • Confirm you have downloaded the correct app: ARPHA Vision.
  • Ensure Bluetooth is enabled on your phone for initial pairing.
  • Restart both the dash cam and your smartphone, then attempt to reconnect.
• Camera Not Powering On:
  • Check if the car charger is properly inserted into the 12V outlet and receiving power.
  • Verify that the Type-C USB Power Cable is securely connected to both the dash cam and the car charger.
  • Test the car charger with another device to ensure it is functional.
• Poor Night Vision Quality:
  • Clean the camera lenses thoroughly.
  • Ensure no obstructions (e.g., stickers, dirt) are blocking the lens.
• ADAS Features Not Functioning Correctly:
  • Verify the front camera is mounted centrally and the lens is clean.
  • Ensure the windshield area in front of the camera is clear of any obstructions or glare.
