Playing a Cassette Tape
Your tape player is built to work best with tapes that are
30 to 45 minutes long on each side. Tapes longer than
that are so thin they may not work well in this player.
Once the tape is playing, use the PWR-VOL-PROG-RCL
knob, just as you do for radio. A lighted arrow will be
displayed to show tape play direction.
FORWARD: Press the arrow button in the direction that
the lighted arrow points to advance quickly to another
part of the tape. Press STOP-EJECT lightly to stop
forwarding and play the tape.
REVERSE: Press the arrow button in the opposite
direction that the lighted arrow points to reverse quickly
to another part of the tape. Press STOP-EJECT lightly
to stop reversing and play the tape.
PWR-VOL-PROG-RCL: Press this knob to go from
one side of the tape to the other.
STOP-EJECT Press this button to remove the tape or
stop playing the tape to play the radio.
