FEATURES
Your Optimus In-Dash High-Power
AM/FM Stereo Cassette with Auto-
Reverse has many practical, easy-
to-use features, and you can install it
in almost any vehicle. 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 op-
eration simple and quick so you can
drive safely.
This stereo’s features include:
Anti-Theft Control Panel — lets
you quickly remove and store the ste-
reo’s control panel in the supplied
carry case. This discourages theft
because the stereo cannot operate
without the control panel.
Continuous Auto-Reverse — а|-
lows continuous play of both sides of
a cassette tape.
Locking Fast-Forward/Rewind —
lets you quickly move the tape to the
beginning or the end without holding
down either button.
Advanced FM Optimizer Circuitry
— automatically adjusts the tuner’s
stereo separation and high-frequen-
cy response to give you the best pos-
sible sound, regardless of the signal
level.
Automatic FM Tuning Adjustment
— automatically changes FM recep-
tion on weak stations from stereo to
mono, to improve reception of those
stations.
Lighted LCD Display with Clock —
lets you easily see the clock/radio/
cassette deck’s current functions.
Band Button — lets you select the
AM or FM band with the push of a
button.
Seek Tuning — searches forward to
the next strong station in the selected
band.
Automatic Seek Sensitivity — ad-
justs your stereo so, the first time it
searches a band, it stops only on
strong local stations; the next time it
searches, it also stops on weaker,
distant stations.

advantage of the improved sound
quality in metal or CrO? tapes.
Bass, Treble, Fader, and Balance
Controls — let you adjust high and
low sounds and the balance between
the left and right and front and rear
speakers, so you can tailor the sound
to suit your preferences.

INSTALLATION
BEFORE YOU BEGIN
THE INSTALLATION
Before you install your stereo, read
all the instructions in the “Installation”
section of this 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 | 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.
Before you mount the stereo, test the
connections by temporarily connect-
ing the power wires, speakers, and
antenna as described in "Making the
Connections" and install the control
panel as described in "Installing the
Control Panel." If you plan to use an
adapter harness to connect the ste-
reo, see "Using an Adapter Har-
ness."
6
Preparing the Mounting
Area
Before you mount the stereo, read
through this "Installation" section to
make sure you have all the neces-
sary materials. Then confirm that the
stereo fits your vehicle's mounting
area.
Caution: Be careful to avoid obstruc-
tions behind the mounting surface.
Notes:
* This autosound stereo system is
a DIN-E size unit that requires a
2'/s inches (54 mm) high by 71/2
inches (190 mm) wide by 8'/2
inches (216 mm) deep mounting
area.
If the mounting area is too large,
you might be able to mount the
stereo with an in-dash installa-
tion kit, available at your local
Radio Shack store. Follow the
installation kit's instructions to
mount the stereo.
Routing Speaker Wire
If you install speakers, avoid routing
the speaker wires near moving parts
or sharp edges. You can usually
route it along the wiring channel be-
neath 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 14-wire harness in-
cludes all the lead wires you need to
connect the stereo to ground, power,
optional components, and speakers.
You might need additional wire, de-
pending on your individual auto
sound system, to complete the con-
nections. Your local Radio Shack
store carries a full line of wire and
Wiring accessories.
Important: Do not cut these wires. If
you cut any wire, you cannot obtain a
refund or exchange on this product.
Radio Shack will provide warranty
service if you cut a wire and find the
product is defective.
Cautions:
* For added safety and to protect
your stereo, disconnect the
cable from your vehicle battery’s
negative (—) terminal before you
begin.
* You must connect the ground,
primary, and memory backup
wires first, then test these con-
nections before you make any
other connections. If you do not
make the connections in the
order shown, damage to the ste-
reo is possible if any wire con-
nections are made incorrectly.
==
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. Your local Radio Shack
store sells adapter harnesses for
most vehicles.
Follow the directions that come with
the adapter harness to connect pow-
er and the speakers.
Connecting Ground, Power,
and Optional Components
Follow these steps to connect the 14-
wire harness to ground, primary and
memory backup power, and optional
components.
1. Disconnect the cable from your
vehicle battery's negative (—)
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 insu-
lated from the chassis by a plas-
tic part.

5 12-2108.fm Page 8 Wednesday, July 14, 1999 10:07 АМ
3. Connect the red power 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 ON
position.
This connection powers the ste-
reo and turns it on when you
turn on the ignition or turn the
key to ACC, and turns off the
stereo when you turn off the igni-
tion. This prevents your vehicle’s
battery from being drained if you
leave the stereo on when you
turn off the ignition.
4. Connect the yellow power/mem-
ory wire (with in-line fuse holder)
to your vehicle battery’s positive
(+) terminal or to a point in your
vehicle’s fuse block that pro-
vides a continuous source of 12
volts.
This connection provides contin-
uous power for the stereo's
clock and tuner memory when
the ignition is turned off.
5. Connect the blue/white wire to
any optional component, de-
signed to run from a switched
source, that you want to turn on
and off when you turn the stereo
on and off (such as an equalizer/
booster).
This wire does not provide
power to the component. It sim-
ply turns it on or off. If you do not
use this wire, secure it with a
wire tie and do not let it touch
metal.
Testing the Power
Connections
Temporarily connect:
* The 14-wire harness into the
stereo's 14-pin wiring socket
* Your vehicle battery's negative
(—) cable
Install the stereo's anti-theft control
panel (see "Installing the Control
Panel"). Then turn on your vehicle's
ignition. Verify that everything works
properly (the stereo works properly
when the display lights and the fre-
quency or time display appears).
If the stereo does not work, immedi-
ately turn off your vehicle's igni-
tion, then unplug the 14-wire har-
ness and your vehicle battery's
negative (—) cable. Recheck your
connections.

If the stereo works properly, discon-
nect:
* The 14-wire harness from the
stereo’s 14-pin wiring socket
* Your vehicle battery's negative
(—) cable
Then proceed with the installation.
CONNECTING
SPEAKERS
You can connect one or two pairs of
speakers to the stereo.
Cautions:
* Be sure your speakers can han-
dle 28 watts of power (14 watts
per channel) Each speaker
must have an impedance of at
least 4 ohms. Your local Radio
Shack store carries a full line of
speakers.
You must connect a separate
wire to each speaker terminal as
described in the following sec-
tions. Do not use a common wire
or chassis ground for any
speaker connection.
Connecting One Pair of
Speakers
If you are using only one pair of
speakers, rotate FADER to its center
position until you feel it click and the
tab on FADER points to the left.
==
Then follow these steps to connect
the 14-wire harness to the speakers.
1. Connect the gray wire to the
right speaker's positive termi-
nal. This terminal is usually
marked with a plus sign (+) or
red mark.
2. Connect the violet/black wire to
the right speaker's negative ter-
minal. 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 green/black wire to
the left speaker's negative termi-
nal.
Connecting Two Pairs of
Speakers
If you are using both front and rear
speakers, follow these steps to con-
nect the 14-wire harness to the
speakers.
1. Connect the gray wire to the
right front speaker's positive ter-
minal. This terminal is usually
marked with a plus sign (+) or
red mark.
2. Connect the gray/black wire to
the right front speaker's nega-
tive terminal. This terminal might
be marked with a minus sign (—)
or it might not be marked at all.

Caution: We recommend you press
2 as soon as you finish playing a
tape or before you leave your vehi-
cle, to release the tape from the tape-
handling parts. This reduces the pos-
sibility of a tape being inadvertently
tangled or damaged.
Notes:
When the tape reaches the end,
the cassette player automati-
cally changes the tape’s direc-
tion and plays the other side of
the tape. Play continues until
you press 2 .
During play, you can switch to
the other side of the cassette by
pressing « and M in.
FAST-FORWARD AND
REWIND
To fast-forward or rewind the current
side, firmly press ХК or depend-
ing on which side of the tape is play-
ing. The button locks and the tape
quickly winds. Play resumes when
the end of the tape side is reached.

CARE AND MAINTENANCE
Your Optimus In-Dash High-Power
AM/FM Stereo Cassette with Auto-
Reverse is an example of superior
design and craftsmanship. The fol-
lowing suggestions will help you care
for the stereo so you can enjoy it for
years.
P Keep the stereo dry. If
it gets wet, wipe it dry
immediately. Liquids
might contain miner-
als that can corrode
the electronic circuits.
Handle the stereo
gently and carefully.
Dropping it can dam-
age circuit boards and
cases and can cause
the stereo to work im-
properly.
©
Keep the stereo away
from dust and dirt,
which can cause pre-
mature wear of parts.
Wipe the stereo with a
M damp cloth occasion-
ally to keep it looking
new. Do not use
harsh chemicals,
cleaning solvents, or
strong detergents to
clean the stereo.
==
Modifying or tampering with the ste-
reo’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 Radio
Shack store for assistance.
THE FCC WANTS YOU
TO KNOW
Your stereo might cause TV or radio
interference even when it is operat-
ing properly. To determine whether
your stereo is causing the interfer-
ence, turn off your stereo. If the inter-
ference goes away, your stereo is
causing the interference. Try to elim-
inate the interference by:
* Moving your stereo away from
the receiver
* Contacting your local Radio
Shack store for help
If you cannot eliminate the interfer-
ence, the FCC requires that you stop
using your stereo.

CLEANING THE ТАРЕ-
HANDLING PARTS
Clean the tape head after about ev-
ery 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 deterio-
rate.
To restore the sound quality, fast-for-
ward 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 sur-
face.
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 FUSES
If the stereo does not operate, you
might need to replace the red power
wire's fuse with the supplied spare
fuse. If the clock resets or stored sta-
tions are lost when the ignition is off,
you might need to replace the yellow
power/memory wire's fuse with the
supplied spare fuse. Check both fus-
es.
1. Disconnect the cable from the
vehicle battery's negative (—)
terminal.
2. Push together and twist the fuse
holder's parts until they spring
open.
3. If either fuse is blown, replace it.
Use only standard 1'/4-inch fast-
acting fuses with the proper rat-
ing. The red power wire's fuse
must be 6.0 amps, and the yel-
low power/memory wire's fuse
must be 0.5 amps.
Caution: The supplied spare
fuses have the proper ratings.
Make sure you replace a fuse
only with another fuse of the
same rating.
