Operating Instructions
Basic Operation:
The VTM43FL mirror monitor features intuitive touch buttons integrated into the mirror's surface. These controls allow you to navigate settings and switch between functions.
- Power On/Off: The monitor typically powers on automatically when the vehicle's ignition is turned on or when the reverse gear is engaged (if the auto reverse trigger is connected).

Video Input Switching:
The VTM43FL supports two video inputs. You can switch between these inputs using the touch controls on the mirror. Refer to the on-screen menu or the 'CH' (Channel) touch button for cycling through available video sources.
Mirror and Normal Image Switch:
Depending on your camera type and preference, you can switch the display between a mirror image (standard for rear-view cameras) and a normal image. This setting is typically found within the monitor's menu accessed via the 'M' (Menu) touch button.
Adjustable Parking Lines:
The monitor can display adjustable parking lines on the backup camera feed to assist with parking maneuvers. These lines can be calibrated to match your vehicle's dimensions and camera angle through the monitor's menu settings.
Maintenance
To ensure the longevity and optimal performance of your BOYO VISION VTM43FL mirror monitor, follow these maintenance guidelines:
- Cleaning the Mirror Surface: Use a soft, lint-free cloth and a non-abrasive glass cleaner to gently wipe the mirror surface. Avoid spraying cleaner directly onto the mirror; instead, apply it to the cloth first.
- Cleaning the Display: For the LCD display area, use a microfiber cloth specifically designed for electronics screens. Do not use harsh chemicals or abrasive materials, as they can damage the screen.
- Cable Inspection: Periodically check all connected cables for any signs of wear, fraying, or damage. Ensure connections remain secure.
- Avoid Extreme Temperatures: While designed for automotive use, prolonged exposure to extreme hot or cold temperatures can affect electronic components.
