· Use only in a 12-volt DC negative-ground electrical system.
· Disconnect the vehicle's negative battery terminal while mounting and connecting the unit.
· 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.
· Keep the volume at a level at which you can hear outside warning sounds (horns sirens, etc.).
· DO NOT open covers and do not repair yourself. Consult the dealer or an experienced technician for help.
· 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.
· Make sure you disconnect the power supply if the system appears to be working incorrectly, is making an unusual sound, has a
strange smell, has smoke emitting from it or liquids have got inside it. Have a qualified technician check the system.
· Stop the car before performing any complicated operation.
· The unit is only designed for use with 4 speakers. Do not combine output for use with 2 speakers. Do not ground negative speaker
leads to the chassis ground.
· Do not install the unit in place where it is exposed to direct sunlight (including the faceplate), in order to avoid high heat.
· The faceplate is a precision piece of equipment that contains sensitive electronic components. Do not subject it to excessive shock.
