Maintenance Features
To ensure optimal performance and longevity, the XVM279BT requires certain maintenance considerations:
- Cleaning: The monitor should be cleaned only with a dry silicone cloth or soft cloth. Avoid using stiff cloths or volatile solvents like paint thinner and alcohol, as these can scratch the screen surface or remove printing.

- Reset Function: In case of abnormal operation or if the unit becomes inoperable, a RESET button is provided. Using the tip of a pen to press this button will reset the main processor to its default settings.
- Environmental Protection: The unit should not be installed in locations exposed to direct sunlight, excessive heat, or potential water splashing. It should also be protected from excessive shock.
- Wiring Integrity: Ensure that the unit is securely grounded to the vehicle chassis. When extending ignition, battery, or ground cables, use automotive-grade cables with an area of 0.75mm (AWG 18) or more to prevent voltage drops.
- Troubleshooting: The manual provides a troubleshooting guide to address common issues such as power problems, no sound, blown fuses, or display issues. If problems persist after attempting troubleshooting steps, users are advised to consult a DUAL dealer or contact technical assistance.
- Liquid Crystal Safety: In the event of damage to the LCD, avoid touching the liquid crystal fluid, as it can be hazardous. If contact occurs, wash the affected area with soap immediately.
