Introduction
Mechanical Installation
Space Requirements:
To mount your new AM/FM cassette
unit, you will need a rectangle hole in
the mounting location 182mm
(width) x 53mm (height), (7⁄8” x 2 1⁄8”)
and a full 6” of unobstructed space
behind the mounting location.
Step 1:
After obtaining the required space
and mounting hole dimensions
required, remove the mounting
sleeve from the unit. Insert the
mounting sleeve into the hole on the
dashboard. Secure it by bending the
tabs inward as shown in fig 1. Select
the appropriate tab according to the
thickness of the dashboard.
Step 2:
Bring the power, ground, antenna
and speaker wires through the center
of the mounting sleeve. Make all the
speaker and power connections to
the main harness supplied with the
unit. Refer to the “wiring” section of
this unit for proper connection. After
all the connections have been made
and are correct, plug the harness and
the antenna cable into the mating
plugs located on the rear of the unit.
Step 3:
Turn on the ignition key and do a
pre-installation check of all the func-
tions with the unit out of the dash-
board to make sure that everything is
operating properly before final instal-
lation.
Step 4:
Securely attach the rear support strap
provided to the rear of the unit with
the fasteners provided. Bend the
strap to allow the unit to slide into it’s
mounting sleeve. Reach up behind
the unit and grab the strap while slid-
ing the unit into the mounting sleeve
until it snaps into place. Secure the
end of the strap to a solid portion of
the dashboard structure or the fire
wall.

Installation Procedure
Removing the Unit:
In the event that the unit requires
removal from it’s mounting location,
repeat the following procedures.
A. Release the rear support strap.
B. Insert the keys provided into the
slot on both sides of the chassis
until locked. (snapped into place)
C. Pull on the keys with equal pres-
sure to release and remove the
unit from the mounting sleeve.
D. Disconnect the wire harness and
the antenna.
Wiring:
Note 1: If you are installing a com-
pletely new system, install all of the
speakers and antenna first, then run
the wires up to the radio mounting
location and bring them through the
radio mounting hole.
Note 2: Your new AM/ FM cassette
unit has been designed to operate
properly when connected to a “12
Volt Negative Ground” electrical sys-
tem. Any other power supply may not
be acceptable. Connecting your new
unit to other than the specified
power source will damage the unit
and will void the warranty. If you are
not sure that your vehicle uses a “12
Volt Negative Ground” electrical sys-
tem, contact your local car stereo
installation center and find out
before making any connections.
Red Wire:
Connect the red wire to a source of
12 volts that is controlled by the igni-
tion key. Use a test light or volt meter
to locate a connection point at the
fuse block.
Black Wire:
Connect the black wire to the frame
of the vehicle. It is strongly recom-
mended that the black wire be con-
nected to a part of the vehicles frame,
floorboard or sub structure to insure
a good ground. It is Not advisable to
connect the black wire to a factory
provided ground wire. It is possible
that many other electrical items will
be connected to this wire and electri-
cal noises such as pops and clicks
could be present in your speakers. In
addition, shared grounds tend to
amplify engine noise into the unit
and you will hear the noise in your
speakers.
Orange Wire: (with fuse holder)
Connect the orange wire to a con-
stant source of 12 volts. The battery
(+) post or the battery portion of the
fuse block is a good location for this
wire. Use a test light or volt meter to
locate a connection point at the fuse
block.

Cassette Operation
Some Notes About Cassette Tapes
* It is not recommended to use any
tape with a length longer than 90
minutes playing time. Longer tapes
create excessive load on the tape
motor and mechanism causing pre-
mature wear and failures. Longer
tapes have a tendency to tangle and
jam automotive tape mechanisms.
* Cassette tape housings that are
warped or that have loose indicator
labels should not be used. Doing so
will result in the tape becoming
jammed in the mechanism.
* Storing cassette tapes in areas
directly exposed to sunlight or
high temperatures will cause the
cassette cases to warp rendering
them unusable. Store cassette tapes
in a case designed specifically for
that purpose. This will prevent
warpage and foreign material cont-
amination.
Periodic Tape Mechanism Cleaning
While the tape is playing, small
deposits of foreign material attach
themselves to the tape head, pinch
rollers and capstans of the tape player
mechanism. Failure to periodically
clean the foreign material off will
result in poor sound quality and a tape
mechanism that will “eat”cassette
tapes. To prevent this from happening,
the use of a good quality “wet type”cas-
sette head and capstan cleaner is rec-
ommended every 10 hours of use.
FAILURE TO CLEAN THE TAPE
DECK AT REASONABLE INTER-
VALS WILL RESULT IN TAPE DECK
SERVICE THAT IS NOT COVERED
BY WARRANTY.
How to Listen to a Tape
1. Turn the vehicles ignition key to
the ON or ACC position to provide
power to the radio.
2. Rotate knob (1) clockwise to turn
on the unit. Adjust the volume
knob (1) to a low listening level.
3. Insert a cassette tape into the the
cassette opening (10) with the
thick side pointing toward the
right
Note: The cassette tape will only fit
in one direction. If the tape does
not insert easily, DO NOT FORCE
IT. Turn the tape over and re-
insert it. At this time the display
(9) will be showing the tape play
indicators (9e)
4. Adjust the volume, bass and treble
controls to suit your taste.
Changing the Tape Program
Cassette tapes have two playing sides,
side (A) and side (B). The cassette
player in this unit will play either side
of the tape. If you wish to change play
from side (A) to side (B) or vise versa,
press and release the FF and REW
buttons at the same time. The tape
play indicator (9E) will show the new
direction and the tape will begin to
play.
Note: If the tape is allowed to run to
the end of the side that is playing , it
will automatically change over to the
remining side and play.

Cassette Operation Programming
Using the Fast Forward and Rewind
Controls
The two buttons located to the right
side of the tape opening (10) are the
fast forward and rewind buttons (11).
While the tape is playing you can use
these buttons to fast advance the tape
to search for special sound tracks or
rewind the tape to listen to it from
the beginning. To operate these but-
tons, simply press one or the other in
until it locks. To release it, press the
opposite button slightly. The “FF”
button will always fast advance the
tape forward and the “REW”button
will always fast rewind the tape.
Listing to the Radio Tuner While Fast
Advancing the Tape

the tape is rewinding or fast forward-
ing, press the “R.FREQ”button after
the FF or REW button is pushed. This
will turn on the radio tuner until the
FF or REW button is released and the
tape begins to play again. Once this
feature is turned on, each time the
“FF and “REW”buttons are pushed,
the radio tuner will come on auto-
matically. If you want to turn this fea-
ture off, press the ‘R.FREQ”button
while the tape is fast forwarding or
