a tape is inserted. The display will show an arrow to
show which side of the tape is playing.

off, first press EJECT or RECALL. Note that the
cassette tape adapter kits for portable compact disc
players will work in your cassette tape player.
Your tape bias is set automatically.
If E and a number appear on the radio display, the tape
won't play because of an error.

tape hubs. Remove the tape. Hold the tape with the

damaged and should not be used in the player.
Try a new tape to make sure your player is
working properly.
E l l : The tape is broken. Try a new tape.
