2. Safety Measures

• Driving Safety: It is forbidden to watch videos or use other visual accessories while driving. Active use of the system while driving is not recommended as it can reduce attention and may lead to traffic violations or accidents.
• Power Supply: The unit is designed for cars with a 12V power supply and a negative ground. Do not install the system in buses or trucks with a 24V on-board voltage, as this may damage the device.
• Screen Care: Use a specialized cleaning device to maintain the screen.
• Temperature Guidelines: To prevent overheating, avoid direct exposure to sunlight and do not install near heating systems. The optimal operating temperature is between 0°C and 35°C. If the vehicle's interior temperature is too high, cool it down before switching on the system. Avoid operating the unit at very low temperatures; wait until the interior temperature returns to normal. Image display may be delayed at low temperatures, which is not a malfunction.
• Installation Fasteners: Only use the provided fasteners (screws, mounting frames, etc.) for installation. Using other fasteners may damage the system and void the warranty.
• Professional Installation: Installation and connection of the device should be performed by a qualified specialist or trained service center staff.
• Factory Reset: Do not reset to factory settings on your own unless absolutely necessary, as this will result in loss of your settings and potentially incorrect system operation.
• Warranty: Violation of these safety measures or improper use may cause system malfunction, in which case warranty service will not be provided.
