(120-2113) Feature Faxback Doc. # 62491

Your Optimus High-Power In-Dash AM/FM Stereo Cassette with Auto-Reverse
has many practical, easy-to-use features, and you can install it in almost
any vehicle. The tuner's digital synthesized PLL (Phase-Locked Loop)
circuitry gives you precise tuning and drift-free reception. The stereo's
anti-theft control panel lets you quickly remove it, making the stereo
inoperative.

The auto-reverse cassette deck, memory tuning, and seek and scan tuning
all help make your stereo's operation simple and quick so you can drive
safely.

CAUTION: Use common sense. Do not change your stereo's settings in heavy
traffic or during hazardous driving conditions.

This stereo's features include:

Anti-Theft Control Panel - lets you quickly remove and store the stereo's
control panel in the supplied carry case. This
discourages theft because the stereo cannot
operate without the control panel.

Auto-Reverse - continuously plays both sides of a cassette
tape.

Fast-Forward/Rewind - lets you quickly move the tape to the beginning
or the end.

Metal/CrO2 Tape Selector - takes advantage of the improved sound quality

of a button.

Seek Tuning - searches forward to the next strong station in
the selected band.

Automatic Seek - adjusts your stereo so the first time it
Sensitivity searches a band, it stops only on strong local
stations; the next time it searches, it also
stops on weaker, distant stations.

High Power - provides 22 watts of total power to give you
excellent audio response for all types of music

Digitally Synthesized - gives you precise tuning and drift-free
Circuitry reception.

Manual/Automatic Memory - lets you manually or automatically store 18 FM
Programming and 12 AM stations into memory groups so you
can quickly tune to those stations.

Memory Scan Tuning - scans all stations in an AM or FM memory group,
stopping for 5 seconds on each station.

Display Color Selector - lets you change the display's color to amber or
green.

Built-in Noise - reduces the noise caused by your vehicle's

(120-2113) Installation Faxback Doc. # 62492

Before You Begin The Installation

Before you install your stereo, read 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?
Which stereo wires are speaker outputs?

Also, be aware that installation in your vehicle might require cutting or
modifying your vehicle.

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.

CAUTION: Be sure to avoid obstructions behind the mounting surface.

Notes: This stereo is a DIN-E size unit that requires a 2-1/16 inches (53
mm) high by 7-3/16 inches (182 mm) wide by 6-11/16-inches (170 mm)
deep mounting area.

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.

Routing Speaker Wires

If you install speakers, avoid routing the speaker wires near moving parts
or sharp edges. You can usually route wires 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 wires, replace the molding.

Removing the Shipping Screw

The shipping screw helps protect the stereo's cassette player from being
damaged during shipment.

Before you mount the stereo, use a Phillips screwdriver to remove the
screw, spacer, and rubber washer from the top of the stereo. This allows
you to remove the mounting sleeve from the stereo.

Note: Save the screw, spacer, and rubber washer in case you ever want to
ship the stereo. You can secure them to the back of the stereo with
a piece of tape.

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.

IMPORTANT: Do not cut these wires. If you cut any wire, you cannot obtain
a refund or exchange on this product. RadioShack will provide
warranty service if you cut a wire and find the product is
defective.

You might need additional wire, depending on your individual auto sound
system, to complete the connections. Your local RadioShack store carries
a full line of wire and wire management accessories.

CAUTIONS: For added safety and to protect your stereo, disconnect the
cable from your vehicle battery's negative (-) terminal before
you begin.

Be sure your speakers can handle 22 watts of power (11 watts per
channel). Each speaker must have an impedance of at least 4 Ohms
Your local RadioShack store carries a full line of speakers.

You must connect the GROUND (-), POWER LEAD (B+), and CLOCK
MEMORY wires first, then make all other connections as described
in the following sections before you plug the harness into the
stereo. If you do not make the connections in the order shown,
an incorrect connection could damage the stereo.

You must connect a separate wire to each speaker terminal as
described in "Connecting Two Pairs of Speakers" and "Connecting
One Pair of Speakers" below. Do not use a common wire or chassis
ground for any speaker connection.

Note: The wiring harness has the following labels:

Using an Adapter Harness

If you are replacing an existing stereo, or if your vehicle has been
factory-wired for autosound components, you can use an adapter harness to
connect the power and speakers. RadioShack stores sell adapter harnesses
for most vehicles.

Follow the directions that come with the adapter harness to temporarily
connect the power and speakers.

After you connect the adapter harness to your vehicle, you can skip
"Connecting Two Pairs of Speakers" or "Connecting One Pair of Speakers"
below.

High-Power In-Dash AM/FM Stereo Cassette w/Auto Reverse
(120-2113) Care and Maintenance Faxback Doc. # 62494

Your Optimus High-Power in-Dash AM/FM Stereo Cassette with Auto-Reverse is
an example of superior design and craftsmanship. The following suggestions
will help you care for the 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.

Handle the stereo gently and carefully. Dropping it can damage circuit
boards and cases and can cause the stereo to work improperly.

Keep the stereo away from dust and dirt, which can cause premature wear
of parts.

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 your stereo's 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 it. Try to eliminate the interference by:

Moving your stereo away from the receiver.

Contacting your local RadioShack store for help.

Cleaning The Tape-Handling Parts

Clean the tape head after about every 20 hours of playing time. Insert a
special head-cleaning cassette (such as Cat. No. 44-1202), and follow the
cleaning cassette's directions to clean the tape head.

Restoring Tape Tension And Sound Quality

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, fast-forward the tape from the beginning to
the end of one side, then completely rewind it. 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.

Replacing A Fuse

If the clock resets or stored stations are lost when the ignition is off,
you might need to replace the yellow continuous power wire's fuse with a
fuse such as Cat. No. 270-1003 (not supplied). If the stereo does not
operate, you might need to replace the red power wire's fuse with a fuse
such as Cat. No. 270-1012 (the supplied spare fuse is one). Check both
fuses.

1. Disconnect the cable from the vehicle battery's negative (-) terminal.

2. To open a fuse holder, pull the latches apart until it opens. Then, to
remove the fuse, gently pull one of the fuse holder's wires up and
pull the fuse off of both wire clips inside the fuse holder.

3. If either fuse is blown, replace it. Use only standard 1-1/4 inch
fuses with the proper rating. The yellow continuous power wire's fuse
must be 0.5 amps, and the red power wire's fuse must be 6 amps.

CAUTION: Make sure you replace a fuse only with another fuse of the
same rating.

4. Reassemble the fuse holders by placing the wires back inside the
holders then squeezing them together until they snap shut.

5. Reconnect the cable to the vehicle battery's negative (-) terminal.

6. Reset your stereo's clock and memory settings as well as other vehicle
accessories.
