PRECAUTIONS

• 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. Laser beams from the optical pickup are dangerous to the eyes.
• 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.
• When your vehicle has been parked in direct sunlight resulting in a considerable rise in the temperature inside, allow the unit to cool off before operating it.
• Keep the volume at a level at which you can hear outside warning sounds (horns, sirens, etc.).
