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.
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.).

can cause dropouts in sound.
Hold CDs as illustrated.
Do not touch the unlabeled side.
Do not attach any seal, label or
data protection sheet to either side of a
