quirements and complies with safety

performance standards of the U.S.

Department of Health and Human

Services.

GENERAL

Anti-Theft Control Panel — lets you

quickly remove and store the stereo

control panel in the supplied carry

case. This discourages theft because

the stereo cannot operate without the

control panel.

Warnings:

Five Preset Equalizer Settings —

tings for enhancing rock, jazz, pop,

classical, or country and western mu-

sic. The equalizer settings also en-

hance any kind of music.

• This system employs a laser light

beam. Only a qualified service

person should remove the cover

or attempt to service this device,

due to possible eye injury.

• The use of controls, adjustments,

or procedures other than those

INSTALLATION

RadioShack store. Follow the

installation kit’s instructions to

mount the stereo.

BEFORE YOU BEGIN

THE INSTALLATION

Before you install your stereo, read all

the instructions in this owner’s manu-

al. You should be able to answer all of

these questions about your vehicle’s

electrical and sound systems.

Cautions:

• Make sure your vehicle’s mount-

ing area is as level as possible. If

you cannot mount the stereo

exactly level, make sure the ste-

reo will not tilt up more than 30

degrees when it is mounted.

• Which of the stereo’s wires is the

power wire?

• Which terminal in my vehicle’s

fuse box is for accessories?

• Be sure to avoid obstructions be-

hind the mounting surface.

• How do I connect a wire to the

fuse box?

Routing Speaker Wires

• Which stereo wires are line-level

outputs and which are speaker

outputs?

If you install speakers, avoid routing

the speaker wires near moving parts

or sharp edges. You can usually route

them 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.

Also, be aware that installation in your

vehicle might require cutting or modi-

fying your vehicle.

Preparing the Mounting Area

Before you mount the stereo, make

sure you have all the necessary mate-

rials. Then confirm that the stereo fits

your vehicle’s mounting area.

Removing the Shipping Screw

The shipping screw helps protect the

stereo’s CD player from being dam-

aged during shipment.

Notes:

• This autosound stereo system is a

DIN-E size unit that requires a 2¹/⁴-

inch (57 mm) high by 7¹/²-inch

(190 mm) wide by 7¹/⁴-inch (186

mm) deep mounting area.

Before you mount the stereo, use a

small Phillips screwdriver to remove

the shipping screw from the top of the

stereo.

• 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

If you do not remove the shipping

screw, you cannot remove the sup-

plied sleeve from the stereo and the

CD player will not work.

12-2152.fm Page 7 Wednesday, July 14, 1999 2:48 PM

Cautions:

• For added safety and to protect

your stereo, disconnect the cable

from your vehicle battery’s nega-

tive (–) terminal before you begin.

(illus)

Note: Save the shipping screw in

case you ever want to mail or ship the

stereo. You can secure it to the back

of the stereo with a piece of tape.

• Be sure your speakers can handle

64 watts of power (16 watts per

channel). Each speaker must

have an impedance of at least 4

ohms. Your local RadioShack

store carries a full line of speak-

ers.

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 compo-

nents, and speakers.

• You must connect the GROUND,

+12V TO IGNITION, and +12V TO

BATTERY 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 con-

nections are made incorrectly.

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 ser-

vice if you cut a wire and find the prod-

uct is defective.

• You must connect a separate wire

to each speaker terminal as

described in the following proce-

dure. Do not use a common wire

or chassis ground for any speaker

connection.

You might need additional wire, de-

pending on your individual auto sound

system, to complete the connections.

Your local RadioShack store carries a

full line of wire and wire management

accessories.

12-2152.fm Page 8 Wednesday, July 14, 1999 2:48 PM

Note: The wiring harness has the fol-

lowing labels.

Connecting Ground, Power,

and Optional Components

Follow these steps to connect the har-

ness with the 14-pin connector to

ground, primary and memory backup

power, and optional components.

Using an Adapter Harness

1. Disconnect the cable from your

–

vehicle battery’s negative ( ) ter-

minal.

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 har-

ness to connect the power and speak-

ers. RadioShack stores sell adapter

harnesses for most vehicles.

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.

Follow the directions that come with

the adapter harness to temporarily

connect the power and speakers.

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 acces-

sory (ACC) or START position.

12-2152.fm Page 9 Wednesday, July 14, 1999 2:48 PM

This connection turns on the ste-

reo 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.

Connecting an Equalizer/

Booster

If you are connecting the stereo to a

separate equalizer or booster, you

need additional wires (not included).

To increase the total power output

from your system, connect the R

(right) and L (left) line output jacks on

the back of the stereo and blue/white

wire, if necessary, to the equalizer or

booster.

4. Connect the yellow power/mem-

ory wire (with transformer and in-

line fuse holder) to your vehicle

battery’s positive (+) terminal or to

a point in your vehicle’s fuse block

that provides a continuous source

of 12 volts.

(illus - show (Blue/White)

Booster

This connection provides power

for the stereo’s components, and

continuous power for the stereo’s

memory when the ignition is

turned off.

(Right) R

(Left) L

5. Connect the blue/white wire to any

optional equipment, designed to

run from a switched source, that

you want the stereo to turn on and

off (such as a booster or a power

antenna).

Check the equalizer/booster’s owner’s

manual for directions.

This wire does not provide power

to the components. It simply turns

them on or off. If you do not use

this wire, secure it with a wire tie

and do not let it touch metal.

Connecting Two Pairs of

Speakers

If you are using both front and rear

speakers, follow these steps to con-

nect the harness with the 14-pin con-

nector to the speakers.

CD PLAYER OPERATION

Cautions:

If a CD is already in the CD player,

simply press CD to play the CD.

The stereo displays CD, DISC

IN, TR:, and the track number of

the track you last played, and the

CD starts to play from the point

where you last stopped it.

• Play only CDs that

have this mark on

them:

• The CD player has

wide

dynamic range. As a result, if you

turn your stereo’s volume up too

high during soft (low volume) sec-

tions of a program, your speakers

might be damaged when a sud-

den loud passage occurs.

After the stereo plays the entire

CD, it automatically repeats all

tracks, starting with Track 1.

Note: If you turn off your vehicle’s

ignition when a CD is loaded, you

must wait about 2 seconds after

you turn the ignition back on before

you can press CD to play the CD.

• If the CD player is jolted during

play, the rotation speed might sud-

denly change or the CD player

might make an unusual noise.

This is not a malfunction.

3. Press AUDIO CONTROL + or – to

increase or decrease the volume

as desired.

Note: See “Adjusting the Con-

trols” on Page 15 for information

about changing the stereo’s other

settings.

CARE AND MAINTENANCE

Your Optimus High-Power In-Dash AM/FM Stereo CD Player is an example of su-

perior 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 can

contain minerals that can corrode electronic circuits.

Handle the stereo gently and carefully. Dropping it can damage the

circuit boards and case and can cause it 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

CLEANER

new. Do not use harsh chemicals, cleaning solvents, or strong deter-

gents to clean the stereo.

Modifying or tampering with the stereo’s internal parts 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 proper-

ly. To determine whether your stereo is causing the interference, turn off your ste-

reo. 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

If you cannot eliminate the interference, the FCC requires that you stop using your

stereo.

CD CARE TIPS

REPLACING A FUSE

Even though a CD is very durable, you

should handle it with care. We recom-

mend the following precautions.

If the clock resets or stored stations

are lost when the ignition is off, you

might need to replace the yellow con-

tinuous power wire’s fuse with the

supplied spare fuse. If the stereo does

not operate, you might need to re-

place the red power wire’s fuse with

the supplied spare fuse. Check both

fuses.

• Keep the CD in its protective case

or sleeve when you are not play-

ing it.

• Handle a CD by its edges to avoid

fingerprints which can prevent the

CD player’s laser beam from

accurately reading the CD. Your

local RadioShack store sells a

suitable CD cleaner kit.

1. Disconnect the cable from the

vehicle battery’s negative (–) ter-

minal.

2. To open the yellow continuous

power wire’s fuse holder, pull the

latches apart until it opens. Then,

if the fuse is blown, gently pull one

of the fuse holder’s wires up and

pull the fuse off of both wire clips

inside the fuse holder.

• Do not write on either side of the

CD, particularly the non-label

side. (Signals are read from the

non-label side.)

• Keep the CD dry. A water drop

can act as a lens and affect the

laser beam’s focus.

• If you park your vehicle in the sun,

temperatures inside the vehicle

can easily reach levels that could

damage your CDs. To prevent

heat damage, avoid leaving your

CDs in your vehicle.

(illus - show yellow fuse holder)

3. To open the red power wire’s fuse

holder, push together and twist

the fuse holder’s parts until they

spring apart. Then remove the

fuse if it is blown.

If a CD skips when you try to play it, it

might be scratched. Your local Ra-

dioShack store sells a Scratch n Fix

kit (Cat. No. 42-127) that might help

remove the scratch and stop the skip.
