EIGHT-TRACK STEREO TAPE PLAYER
NOTE: When removing tape player knobs on F
Series, insert a small allen wrench (Fig. 15-51),
pointed tool or wire (awl, etc.) in slot on side o f
knob and release inner retainer by prying out-
ward (away from dash). While releasing re-
tainer, pull knob OK
The Stereo Tape Player allows the owner to make his own
selection of pre-recorded music. It uses a standard eight-
track cartridge and may only be ordered with a radio. The
tape player is turned on by completely inserting a cartridge
into the unit. The insertion of a tape cartridge automati-
cally removes power from the radio and switches the
speakers from the radio to the tape player. This feature
prevents accidental damage to the radio should the owner
attempt to operate it while the tape player is in use. After
the tape player is in operation, the front panel controls of
the player are then adjusted for the most pleasant stereo
listening.
The unit is equipped with a cartridge locking arm to hold
the cartridge in a rigid position against the capstan drive
for minimum "wow" and "flutter". As the cartridge is
withdrawn from the player, the on/off switch at the other
side of the cartridge is not completely disengaged when
the lock arm reaches a detent point on the cartridge.
CAUTION: Always pull cartridge approxi-
mateJy one inch out of tape player when not in
use. If this is not done, the tape may be pulled
out of the cartridge and wound around the cap-
stan when player is re-started.
The tape player speaker system is the same as described
under "AM-FM Stereo Radio.".
MAINTENANCE AND CAUTIONS
The only required maintenance on tape players is periodic
cleaning of the tape player head. This service should be
performed every 100 hours of operation. The head clean-
ing is done by swabbing the head (unit still installed in car)
with a cotton swab that has been dipped in alcohol.
No lubricants should be used since they will cause the
player to operate improperly, especially at extreme tem-
peratures.
Do not bring any magnetized tools near the tape head. If
the head becomes magnetized, every cartridge played in
the player will be degraded.
CASSETTE STEREO TAPE PLAYER
A cassette tape player is available in conjunction with a
radio. Mounted on a transmission tunnel pod or the top
of console, this unit uses standard cassette tape cartridges.
To operate the tape player, insert the cartridge and close
the tape door. This automatically transfers power and
speaker connections from the radio to the tape player.

button firmly. Tape door will pop up. Insert Cassette
cartridge with tape facing toward you.

place. Player will start within a few seconds. If no tape is
inserted, player will remain OFF.
TO REMOVE TAPE CARTRIDGE-Push "TAPE RE-

insert to hear Side Two.
TO REWIND TAPE-Side One is automatically re-wound
when Side Two is played. However, you may re-wind Side
One without playing Side Two by pressing the "RE-
VERSE" button. When you reach the beginning, tape will
stop.
TO SKIP PORTIONS OF TAPE-Simply hold in the "For-
ward" button and the tape runs forward rapidly. Release

cartridge is inserted in player. (The Tape-In light comes

REAR SEAT SPEAKER
The rear speaker system with AM or AM-FM radios
employs a single rear speaker which, together with the
front speaker, is controlled by a switch incorporated into
the righthand bezel on the radio receiver.
The speaker control features a "Fader" operation which
provides a variable volume control for both front and rear
speakers. Extreme counterclockwise switch position is
front speaker only; while extreme clockwise position is
rear speaker only. Positions between these extremes give
varying amounts of front or rear volume.
