· When replacing the fuse, be sure to use one with an identical amperage rating. Using a fuse with a higher amperage rating may
cause serious damage to the unit.
· DO NOT attempt to disassemble the unit.
· Make sure that pins or other foreign objects do not get inside the unit; they may cause malfunctions, or create safety hazards such as
electrical shock or laser beam exposure.
· If you have parked the car for a long time in hot or cold weather, wait until the temperature in the car becomes normal before
operating the unit.

· Make sure you disconnect the power supply and aerial if you will not be using the system for a long period or during a
thunderstorm.

strange smell, has smoke emitting from it or liquids have got inside it. Have a qualified technician check the system.
