PRECAUTIONS
e When replacing the fuse(s), the replacement must be of the same amperage as
shown on the fuse holder. If the fuse(s} blows more than once, carefully check all
electrical connections for shorted circuitry. Also have your vehicle’s voltage regulator
checked. Do not attempt to repair the unit yourself. Return it to your Alpine dealer or
the nearest Alpine Service Station for servicing.
e In order to ensure proper performance, be sure the temperature in your vehicle is
between the range of 14° F (—10°C) to 140°F (60°C) before turning your player on.
Good air circulation is essential to prevent heat build-up in the unit (especially in hot
weather).
e C-120 type cassette tapes are not recommended for use in automobile tape players.
e Prevent any foreign objects from entering the cassette opening as the precision
mechanism and tape head may be damaged.
e 10 protect your cassette tapes, store them in a cool place away from dust, dirt, and
strong magnetic sources such as electric motors, speakers and TV sets.
e Check and make sure any slack in the tape is taken up before inserting the tape into
the unit. A loose tape could cause damage to the unit and the tape itself. Tighten the
cassette by inserting a pencil or a similar instrument into the spindle hole and turn until
all the slack has been taken up.
e Use of this equipment at high volumes could damage your hearing.
e CAUTION:
In the event of road vibration or rapid acceleration or vehicle collision, this unit may
become dislodged from its case unless the handle is fully down. This could result in
personal injury to occupants of the vehicle or physical damage to the unit. Please see
the illustrations below for further information on how to properly secure the handle.
e CAUTION:
The heat sink on the rear of the unit will become hot after operation. Exercise caution
when the unit is removed from the Q.R. Bracket.
