3. Operating Instructions
The Kenwood CMOS-230 Backup Camera provides a clear, wide-angle view to assist with reversing maneuvers when connected to a compatible monitor.
Basic Operation:
- Activation: The camera automatically activates when the vehicle is shifted into reverse gear, provided it is correctly wired to the vehicle's reverse light circuit.
- Display: The camera's video feed will appear on your connected monitor (e.g., an LCD display) when activated.
- Viewing Angle: The 130-degree real angle of view provides a broad perspective of the area behind your vehicle, enhancing situational awareness.
- Image Orientation: The camera outputs a wide-angle mirror image, which is standard for rear-view applications to match typical mirror perception.
Always check your surroundings visually in addition to using the backup camera. The camera is an aid and does not eliminate blind spots entirely.
4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Kenwood CMOS-230 Backup Camera.
Care and Cleaning:
- Lens Cleaning: Periodically clean the camera lens using a soft, damp cloth. Avoid abrasive cleaners or materials that could scratch the lens.
- Housing Cleaning: Wipe the camera housing with a mild detergent solution and a soft cloth. Rinse thoroughly with clean water.
- Inspection: Regularly inspect the camera and its mounting bracket for any signs of damage, corrosion, or loose connections.
- Cable Integrity: Check the wiring for any cuts, fraying, or signs of wear. Ensure all connections remain secure and waterproof.
Do not use high-pressure washers directly on the camera lens or housing, as this may compromise its waterproof seal.
