INSTALLATION

7¹/²-inch wide by 7¹/⁴-inch deep (57 ¥

190 ¥ 186 mm) mounting area.

BEFORE YOU BEGIN

THE INSTALLATION

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 in-

structions to mount the stereo.

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.

• Which terminal in my vehicle’s

fuse box supplies power even

when the ignition is turned off?

Cautions:

• Make sure the stereo will not tilt

up more than 30 degrees when it

is mounted.

• 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?

Also, be aware that installation in your

vehicle might require cutting or modi-

fying your vehicle.

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 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.

Place the stereo as close as possible

to the selected mounting location. We

recommend that you install the stereo

by temporarily connecting it to ground

and power, optional components, and

your speakers. Then test the connec-

tions, disconnect the stereo, mount it in

your vehicle, and reconnect it. The in-

structions in this manual are arranged

in this order.

Removing the Shipping

Screw

Preparing the Mounting Area

The shipping screw helps protect the

stereo’s CD player from being dam-

aged during shipment.

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. This au-

tosound stereo system is a DIN-E size

unit that requires a 2¹/⁴-inch high by

Before you mount the stereo, use a

Phillips screwdriver to remove the

shipping screw from the top of the ste-

reo.

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.

However, your local RadioShack store

will provide warranty service if you cut

a wire and find the product is defec-

tive.

• 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 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 the following colors and 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.

(illus)

1. Disconnect the cable from your

Using an Adapter Harness

–

vehicle’s negative ( ) battery 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.

Follow the directions that come with

the adapter harness to temporarily

connect the ground, power, optional

components, and speakers. Then go

to “Connecting the Antenna” on

Page 11.

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.

12-2154.fm Page 9 Wednesday, July 14, 1999 3:34 PM

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.

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 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)

This connection provides power

for the stereo’s components (such

as the CD player), and continuous

power for the stereo’s memory

when the ignition is turned off.

Check the equalizer/booster’s owner’s

manual for directions.

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).

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.

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.

12-2154 Only: Before connecting the

speakers, remove the tape that holds

the mounting sleeve in place and slide

the sleeve off of the stereo. Then set

2CH/4CH on the bottom of the stereo

to 4CH.

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

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 cir-

cuit 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 deter-

gents to clean the stereo.

Modifying or tampering with the stereo’s internal components can cause a malfunc-

tion, invalidating your stereo’s warranty and voiding your FCC authorization to oper-

ate 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 stereo does not operate, you

might need to replace the red power

wire’s 1-amp 1¹/⁴-inch fuse with the

supplied spare fuse (Cat. No. 270-

1005). If the clock resets or stored sta-

tions are lost when the ignition is off,

you might need to replace the 10-amp

blade-type fuse on the stereo’s back

panel with the supplied spare fuse

(Cat. No. 270-1081). Check both fus-

es.

• 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.

Caution: Do not use a fuse with rat-

ings other than those specified here.

Doing so might damage your stereo.

• Do not write on either side of the

CD, particularly the non-label

side. (Signals are read from the

non-label side.)

Replacing the Red Power

Wire’s Fuse

• Keep the CD dry. A water drop

can act as a lens and affect the

laser beam’s focus.

1. Disconnect the cable from your

–

vehicle’s negative ( ) battery ter-

• 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.

minal.

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.
