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.
• 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.
• 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.).
CAUTION
• DO NOT open covers and do not repair
yourself. Consult the dealer or an
experienced technician for help.
BEFORE OPERATION
• Do not raise the volume level too much,
as this will block outside sounds, making
driving dangerous.
• Stop the car before performing any
complicated operation.
