• 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.
• Keep screwdrivers, etc. and other metallic or magnetic
objects away from the playback head.
• 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.).
