Otherwise, it will obstruct the front line of sight or obstruct moving parts, etc., causing serious accidents. - DO NOT TOUCH THE PRODUCT DURING OPERATION The temperature of the product rises during operation, so touching it can cause burns.
NOTICE
- This symbol indicates important instructions. Failure to heed these instructions may result in injury or major property damage.
- WHEN THERE IS A PROBLEM, PLEASE STOP USING IT IMMEDIATELY
Otherwise, it may cause personal injury or damage to the product. Please return this product to an authorized Alpine dealer or the nearest Alpine service center for repair. - ASK PROFESSIONALS FOR WIRING AND INSTALLA- TION
The wiring and installation of this product require professional skills and experience. For safety reasons, please contact the dealer where you purchased the product for installation. - USE DESIGNATED ACCESSORIES AND INSTALL SECURELY
Make sure to use only designated accessories. The use of non-designated parts may cause internal damage to the device, or it may not be securely installed in place. This can cause parts to loosen and cause danger or product failure. The recommended torque for tightening the screws between the mounting bracket and the product is 37±5 N/cm. A higher torque may cause damage to the screw hole. - ARRANGE THE WIRES TO AVOID CRIMPING OR BEING SQUEEZED BY SHARP METAL EDGES
The arrangement of wires and cables should be far away from moving parts (such as seat tracks) or sharp edges or corners. This will avoid crimping and damage to the wires. If the wiring passes through a metal hole, a rubber gasket should be used to prevent the wire insulation from being cut by the edge of the metal hole. - DO NOT INSTALL IN HIGH HUMIDITY OR DUSTY LOCATIONS
Avoid installing the device in a location with high humidity or dust. Moisture or dust invades the device and can cause product failure.
Precautions
- PRODUCT CLEANING
Please use a dry, soft cloth to clean the product regularly. If the dirt is difficult to remove, soak a soft cloth with water only. Any other solvent may dissolve the surface. - TEMPERATURE
