Fuse Replacement
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.
Temperature in the vehicle
In order to ensure proper performance, be sure the temperature in your vehicle is
between 14° F (—10°C) and 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).
Excessively Thin Tape
C-120 type cassette tapes are not recommended for use in automobile tape players.
Precision Mechanism
Prevent any foreign objects from entering the cassette opening as the precision
mechanism and tape head may be damaged.
Storage
To 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.
Tape Slack
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.

strongest station in preset No. 6. When seeking stations, the tuner first seeks in the
local tuning mode. If less than 6 stations are memorized, the tuner seeks again in the
distance (DX) mode.
After finishing the auto memory preset, the tuner goes to the station placed in preset
memory No. 1. If no stations are memorized, It returns to the original station you were
