Playing a Cassette Tape

EJECT or RECALL. Then, insert
the cassette tape.

begin playing.
Once the tape is playing, use the VOL, AUTO TONE,

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

the display.

the tape to the other.
NEXT (3): Press the NEXT button or the SEEK right
arrow to search for the next selection.
A minimum

will mute while searching for the next selection.
REV (4): Press this button to rapidly reverse the tape to
the beginning of the cassette or until you press
