Playing a Cassette Tape
Your tape player is built to work best with tapes that
are up to 30 to 45 minutes long on each side. Tapes
longer than that are so thin they may not work well in
this player.
To load a cassette tape with the ignition off, press EJECT
or RECALL. Then, insert the cassette tape. If the ignition
is on but the radio is off, the tape will begin playing.
Once the tape is playing, use the VOL, AUTO TONE,
BAL, FADE, BASS and TREB controls just as you
do for the radio. The tape symbol and a direction arrow
will be on the display whenever a tape is being played.
Anytime a tape is inserted, the top side is selected for
play first.
The player automatically senses if the cassette tape is
metal or CrO and adjusts for best playback sound.
