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

•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.).
