Setup and Installation
This extension cable is designed to extend the reach of your V80-4CH dash cam's rear camera. Follow these steps for proper installation:
- Identify Connectors: Locate the 4-pin male connector on your dash cam's rear camera cable and the 4-pin female connector on the main dash cam unit or existing cable.
- Connect Extension Cable:
- Connect the male end of the extension cable to the female port of your dash cam's main unit or existing cable.
- Connect the female end of the extension cable to the male connector of your rear camera cable.
- Secure Connections: Ensure both connections are firmly seated to prevent signal loss.
- Route Cable: Carefully route the extension cable through your vehicle's interior, avoiding areas that could pinch or damage the cable. Use the provided installation tool (if applicable) to tuck the cable neatly along trim panels or under carpets.
- Test Functionality: After installation, power on your dash cam system and verify that the rear camera is receiving power and transmitting video correctly.
Operating Instructions
The HUPEJOS V80-4CH extension cable operates passively, extending the connection between your dash cam and its rear camera. Once properly installed, it requires no further direct operation. The functionality of the rear camera will be controlled by your main dash cam unit.
Maintenance
- Cleaning: Wipe the cable with a soft, dry cloth if it becomes dusty. Do not use harsh chemicals or abrasive cleaners.
- Inspection: Periodically inspect the cable for any signs of wear, cuts, or damage, especially at the connectors.
- Storage: If removing the cable for storage, coil it loosely to prevent kinking and store it in a cool, dry place.
Troubleshooting
No Signal from Rear Camera:
- Check Connections: Ensure both ends of the extension cable are securely connected to the dash cam and the rear camera.
- Inspect Cable: Look for any visible damage to the extension cable. A damaged cable may need replacement.
- Test Without Extension: If possible, test the rear camera by connecting it directly to the dash cam (without the extension cable) to rule out issues with the camera or main unit.
Intermittent Signal:
- Secure Connections: Loose connections are a common cause of intermittent signals. Re-seat both connectors firmly.
- Cable Routing: Ensure the cable is not being pinched or stressed by vehicle components.
