INSTALLATION
BEFORE YOU BEGIN THE
INSTALLATION
Before you install your stereo, we recommend you read through all the instructions in this Owner’s Manual. You
should be able to answer all of these
questions about your vehicle’s electrical
and sound systems.
• Which terminal in my vehicle’s fuse
box is for accessories?
• How do I connect a wire to the fuse
box?
• Which of the stereo’s wires is the
power wire and which are speaker
outputs?
Also, be aware that installation in your
vehicle might require cutting or modifying
your vehicle.
Place the stereo as close as possible to
the selected mounting location. We recommend that you test the connections by
temporarily connecting the ground and
power wires, your speakers, and an antenna. After you test the connections
(see “Testing the Connections” on
Page 7), disconnect the stereo, mount it
in your vehicle, and then reconnect it.
The instructions in this manual are arranged in this order.
Caution: Be sure your speakers can
handle 7 watts of power (3.5 watts per
channel). Each speaker must have an
impedance of at least 4 ohms. Your local RadioShack store carries a full line
of speakers.
4
Preparing the Mounting Area
Before you mount the stereo, make sure
you have all the necessary materials.
Then confirm that the stereo fits your
vehicle’s mounting area. This autosound stereo system is a shaft-type unit
that requires a 115/16-inch (50 mm) high
by 61/2-inch (164 mm) wide by 43/4-inch
(120 mm) deep mounting area.
Note: If the mounting area is too large,
you might be able to mount the stereo
with an in-dash installation kit, available
at your local RadioShack store. Follow
the installation kit’s instructions to mount
the stereo.
Caution: Be sure to avoid obstructions
behind the mounting surface.
Routing Speaker Wires
If you install speakers, avoid routing the
speaker wires near moving parts or
sharp edges. You can usually route them
along the wiring channel beneath the vehicle’s door facings by carefully removing the molding that holds the carpet in
place. After you route the speaker wires,
replace the molding.
MAKING THE
CONNECTIONS
The supplied harness with the 14-pin
connector includes all the lead wires you
need to connect the stereo to ground,
power, some optional components, and
speakers.
12-2004a.fm Page 5 Friday, January 21, 2000 4:45 PM
Important: Do not cut these wires. If you
cut any wire, you cannot obtain a refund
or exchange on this product. However,
your local RadioShack store will provide
warranty service if you cut a wire and find
the product is defective.
You might need additional wire, depending on your individual autosound system,
to complete the connections. Your local
RadioShack store carries a full line of
wire and wire management accessories.
Note: The wires in the wiring harness
have these colors and labels.
AMP REMOTE TURN ON 500 MA
POWER LEAD (B+)
GROUND (–)
Blue
Red
Black
Cautions:
• For added safety and to protect your
stereo, disconnect the cable from
your vehicle’s negative (–) battery
terminal before you begin.
• You must connect the GROUND (–)
and POWER LEAD (B+) wires first,
then make all other connections as
described in the following sections
before you plug the harness with the
14-pin connector into the stereo. If
you do not make connections in the
order shown, damage to the stereo
is possible if any wire connections
are made incorrectly.
• You must connect a separate wire to
each speaker terminal as described
in the following procedure. Do not
use a common wire or chassis
ground for any speaker connection.
Using an Adapter Harness
If you are replacing an existing stereo,
or if your vehicle has been factory-wired
for autosound components, you might
be able to use an adapter harness to
connect the power and speakers. RadioShack stores carry adapter harnesses for most vehicles.
Follow the directions that come with the
adapter harness to temporarily connect
the ground and power wires, optional
components, and speakers. Then go to
“Connecting the Antenna” on Page 7.

1. Disconnect the cable from your vehicle’s negative (–) battery terminal.
2. Connect the black GROUND (–) wire to a chassis ground, such as a metal screw
attached to a metal part of the vehicle’s frame. Be sure that the screw is not insulated from the chassis by a plastic part.
3. Connect the red POWER LEAD (B+) wire (with in-line fuse holder) to a point in your
vehicle’s fuse block that has power only when you turn the vehicle’s key to either
the accessory (ACC) or START position.
This connection turns on the stereo when you turn on the ignition or turn the key
to ACC, and turns off the stereo when you turn off the ignition. This prevents your
vehicle’s battery from being drained if you leave the stereo on when you turn off
the ignition.
4. Cut the loop at the end of the blue AMP REMOTE TURN ON 500MA MAX wire, strip
about 1/2 inch of insulation from its end, then connect it to any optional equipment
(designed to run from a switched source) that you want the stereo to turn on and
off (such as a power antenna).
This wire does not provide power to the components. It simply turns them on or
off.
6
12-2004a.fm Page 7 Friday, January 21, 2000 4:45 PM
If you do not use this wire, secure it
with a wire tie and do not let its bare
wire ends touch metal (if you cut it).
Connecting Speakers
1. Connect the gray wire to the right
speaker’s positive terminal. This terminal is usually marked with a plus
(+) sign or red mark.
2. Connect the gray/black wire to the
right speaker’s negative terminal.
This terminal might be marked with
a minus (–) sign or it might not be
marked at all.
3. Connect the white wire to the left
speaker’s positive terminal.
4. Connect the white/black wire to the
left speaker’s negative terminal.
Connecting the Antenna
Connect the vehicle’s antenna cable to
the antenna jack on the back of the stereo.
Completing the Connections
After you have securely made all other
connections, plug the harness’ connector into the stereo’s 14-pin wiring socket.

MOUNTING THE STEREO
Setting the Shaft Spacing
3. Loosen the shaft nuts on both
shafts. Then move each shaft positioner to the correct pair of holes as
shown.
The size of pre-existing openings in the
dash or installation kit determines the
best spacing between the stereo’s shafts
(knobs).
The space between the shafts is preset to
51/8 inches (130 mm). If needed, you can
change the spacing to 53/8 inches (136
mm), 59/16 inches (142 mm), or 513/16 inches (148 mm).
Measure the size of the pre-existing
openings in the dash or installation kit.
Then, if you need to change the shaft
spacing, follow these steps.
1. Make sure the ignition is turned off,
then disconnect the cable from your
vehicle’s negative (–) battery terminal.
2. Disconnect the wiring harness and
the antenna.

CARE AND MAINTENANCE
Your RadioShack AM/FM Cassette Car
Stereo is an example of superior design
and craftsmanship. The following suggestions will help you care for your stereo so you can enjoy it for years.
Keep the stereo dry. If it
gets wet, wipe it dry immediately. Liquids might
contain minerals that can
corrode the electronic circuits.
Keep the stereo away
from dust and dirt, which
can cause premature
wear of parts.
Handle the stereo gently
and carefully. Dropping it
can
damage
circuit
boards and cases and
can cause the stereo to
work improperly.
Wipe the stereo with a
damp cloth occasionally
to keep it looking new. Do
not use harsh chemicals,
cleaning solvents, or
strong detergents to clean
the stereo.
Modifying or tampering with the stereo’s
internal components can cause a malfunction and might invalidate its warranty
and void your FCC authorization to operate it. If your stereo is not performing as
it should, take it to your local RadioShack
store for assistance.
THE FCC WANTS YOU TO
KNOW
Your stereo might cause TV or radio interference even when it is operating
properly. To determine whether your stereo is causing the interference, turn off
your stereo. If the interference goes
away, your stereo is causing the interference. Try to eliminate the interference
by:
• moving your receiver away from the
stereo
• contacting your local RadioShack
store for help
If you cannot eliminate the interference,
the FCC requires that you stop using
your stereo.
CLEANING THE TAPEHANDLING PARTS
Dirt, dust or particles of the tape’s coating can accumulate on the tape heads
and other parts that the tape touches.
This can greatly reduce the performance
of the cassette player. After every 20
hours of tape player operation, use a
cassette deck cleaning kit (Cat. No. 441202) to clean the tape-handling parts.
Follow the directions provided with the
cleaning kit to use it.

12-2004a.fm Page 14 Friday, January 21, 2000 4:45 PM
RESTORING TAPE
TENSION AND SOUND
QUALITY
2. To open the fuse holder, push
together and twist the fuse holder’s
parts until they spring open. Then
remove the fuse.
After you play a cassette tape a few
times, the tape might become tightly
wound on the reels. This can cause playback sound quality to deteriorate.
To restore the sound quality, fastforward the tape from the beginning to
the end of one side, then turn the tape
over and fast-forward it to the end again.
Then loosen the tape reels by gently tapping each side of the cassette’s outer
shell on a flat surface.
Caution: Be careful not to damage the
cassette when tapping it. Do not touch
the exposed tape or allow any sharp objects near the cassette.
3. If the fuse is blown, replace it with
the supplied spare fuse. Use only a
standard 11/4-inch fuse with the
proper rating. The fuse must be
rated at 3 amps.
Caution: The supplied spare fuse
has the proper rating. Make sure
you replace the fuse only with
another fuse of the same rating.
4. Reassemble the fuse holder by
pushing together and twisting the
two parts back together.
REPLACING THE FUSE
If the light on the front of the stereo does
not turn on or the stereo does not operate, you might need to replace the red
power wire’s 3-amp fuse with the supplied spare fuse or another fuse such as
Cat. No. 270-1009.
Caution: Do not use a fuse with ratings
other than those specified here. Doing so
might damage your stereo.
Follow these steps to replace your stereo’s fuse.
1. Disconnect the cable from your vehicle’s negative (–) battery terminal.
