A. Bill the Ford Dealer for re-
placement parts and for labor as
agreed upon between you and the

guarantee Ford receiver.

B. The model and serialnumber
of each re ceiver, the description
of repair, the Motorola or Ford
number of the parts replaced
should appear on your invoice to
the dealer.

C. All defective parts should be

ESSARY so that he may receive
his adjustment from the Ford

completely or at least 1" from its
seated position before radio will

of the tape slot. Adjustvolume, tone
and balance as required.

removed from the tape slot, the unit
automatically switches from tape
operation to AM radio operation.

TAPE PLAYER DRIVE & HEAD
POSITIONING

The View shown below is one looking
into the tape player from the front
with a tape cartridge inserted and
operating.

When the tape cartridge is inserted
into the tape slot and with the unit
turned on, the radio-tape switch (on
radio-tape models) switches the in-
put of the audio system from the
radio circuitry to tape pre-amp cir-
cuitry. At the same time, the front
of the tape cartridge activates a
micro- switch which, in turn, turns
on the tape motor.

The drive belt on the motor shaft
drives the flywheel causing it to
rotate. The flywheel shaft(capstan)
which presses the tape against the
rubber pressure roller (inside the
cartridge) drives the tape. The tape

guide bracket keeps the tape from
riding up and down the head,

Since the pre-recordedtape has four
dual channel programs (8 tracks),
the head has to be moved to four
different height positions with re-
spect to the tape, The sequence of
head movement is as follows:

Tracks 1 and 5
Tracks 2 and 6
Tracks 3 and 7
Tracks 4 and 8

Tracks 1 and 5 (return to original
tracks)

The positioning of the head can be
accomplished either manually or
automatically. Manual positioning
is accomplished whenever the chan-
nel selector switch (on volume con-
trol shaft) is pushedinand released.

switch returns one end of the sole-
noidwinding to ground. The resultant
magnetic field in the solenoid pulls
in the solenoid's spring loaded shaft
for an instant; when the shaft returns
to its original position, it detents the
ratchet end of the cam shaft to its
next position, In contact with the
irregularly shaped cam is the tape
head transfer pin (located beneath
the head) which moves the head up
or down.

Automatic positioning of the head to
the next dual channel program is
accomplished by the tape itselfwhen
the end of a program is reached.
The pre-recorded tape has, at the
end of the recorded programs, a
strip of conductive tape which shorts
out the switch track which is in
contact with the tape at all times.
This switch is wired inparallelwith
the channel selector switch which
starts the same actionthat occurred
with the channel selector switch was
activated,
