3.2 Wiring Connections
- Power Connection: Connect the monitor's power cable to a DC12V power source in your vehicle. Ensure proper polarity (red to positive, black to negative).
- Video Input: The monitor features two video input jacks. Connect your backup camera's video output cable to either of these inputs. If using multiple video sources, connect them to the available inputs.
- Auto Reverse Trigger: For automatic activation when reversing, connect the designated trigger wire from the monitor to your vehicle's reverse light circuit. This will automatically switch the display to the backup camera feed when the vehicle is put into reverse.
It is recommended to have installation performed by a qualified professional to ensure correct wiring and optimal performance.
4. Operating Instructions
4.1 Powering On/Off
The monitor will typically power on automatically when the vehicle's ignition is turned on, or when the auto-reverse trigger is activated. Consult your installer for specific power configurations. To manually power on/off, use the designated power button, if available, usually located on the rear of the unit.
4.2 Adjusting Display Settings
The VTM4000 monitor includes brightness and contrast adjustments. These settings are typically accessed via three small buttons located on the rear of the monitor. Adjust these settings to achieve optimal image clarity and visibility under various lighting conditions, including bright sunlight. A removable sun shield is also provided to help reduce glare.
4.3 Video Input Switching
If two video sources are connected, the monitor may automatically switch between them based on the auto-reverse trigger, or you may be able to manually switch inputs using a dedicated button on the monitor.
5. Care and Maintenance
- Cleaning: Use a soft, dry cloth to clean the monitor screen and casing. For stubborn marks, lightly dampen the cloth with water. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the display and finish.
- Temperature: Avoid exposing the monitor to extreme temperatures, both hot and cold, for extended periods.
- Moisture: Keep the monitor dry. Do not expose it to rain or moisture.
- Mounting: Periodically check the suction cup mount for secure attachment, especially in varying temperatures.
