INTRODUCTION

Your Optimus AMX-10 Stereo Ampli-

fied Speakers are specially designed

for use with computer multimedia sys-

tems. The speakers’ magnetic shield

allows you to place them next to your

PC’s monitor without causing picture

distortion.

The speakers also transform your por-

table CD player or personal cassette

player into a complete music system.

The speakers are compatible with any

audio source that has a 1/8-inch stereo

headphone or line out jack.

Your speakers’ features include:

31/2-Inch Full-Ran

e Speakers —

give you excellent, wide-range sound.

Bass Boost and Treble Controls —

let you adjust the speakers’ low and

high frequency response to enhance

the sound.

POWER SOURCES

You can power your speakers from in-

ternal batteries, standard AC power,

or vehicle battery power.

Using Batteries

You can power the speakers from

eight C batteries (four in each speak-

er). For the best performance, we rec-

ommend alkaline batteries, such as

RadioShack Cat. No. 23-651.

1. Press the tab on each speaker’s

battery compartment cover, then

lift off the cover.

2. Put four batteries into each

speaker’s compartment, as indi-

cated by the polarity symbols (+

and –) marked inside the compart-

ment.

Caution: Use only fresh batteries

of the required size and type.

3. Replace the cover.

Notes:

• If you will not be using the speak-

ers for a week or more, or if you

will be using only AC or vehicle

battery power, remove the batter-

ies from each speaker.

• If the speakers’ sound weakens or

distorts, or the power indicator

dims during use, replace all the

batteries in both speakers.

Caution: Always dispose of old bat-

teries promptly and properly.

Using AC Power

You can power your speakers from a

standard AC outlet using a 12-volt AC

adapter (not supplied), such as Ra-

dioShack Cat. No. 273-1653.

Cautions:

• The recommended adapter sup-

plies 12 volts DC power and deliv-

ers at least 600 milliamps. Its

center tip can be set to positive,

and its plug properly fits the right

speaker’s DC 12V jack. Using an

adapter that does not meet these

specifications could damage the

speaker or the adapter.

• Always plug the AC adapter into

the speaker before you plug it into

the AC outlet. Always unplug the

AC adapter from the AC outlet

before you unplug it from the

speaker.

Follow these steps to use AC power.

1. Make sure POWER OFF/ON is set

to OFF.

2. Plug the 5.5 mm outer diameter/

2.1 inner diameter barrel plug into

the AC adapter cord, matching

TIP to positive (+).

3. Plug the adapter’s barrel plug into

the DC 12V jack on the rear of the

right (R) speaker.

4. Plug the adapter into a standard

AC outlet.

Note: Connecting an AC adapter au-

tomatically disconnects internal batter-

ies.

Using Vehicle Battery Power

You can power the speakers from

your vehicle’s cigarette-lighter socket

using a DC adapter (not supplied),

such as RadioShack Cat. No. 270-

1562.

Cautions:

• The recommended adapter sup-

plies 12 volts DC power and deliv-

ers at least 600 milliamps. Its

center tip can be set to positive,

and its plug properly fits the right

speaker’s DC 12V jack. Using an

adapter that does not meet these

specifications could damage the

speaker or the adapter.

• Always plug the DC adapter into

the speaker before you plug it into

the cigarette-lighter socket.

Always unplug the DC adapter

from the cigarette-lighter socket

before you unplug it from the

speaker.

Follow these steps to use vehicle bat-

tery power.

1. Make sure POWER OFF/ON is set

to OFF.

2. Put the 5.5 mm outer diameter/2.1

inner diameter barrel plug into the

AC adapter cord, matching TIP to

positive (+).

3. Set the adapter’s voltage switch to

12 volts.

4. Plug the adapter’s barrel plug into

the DC 12V jack on the rear of the

right (R) speaker.

5. Plug the other end of the adapter

into the vehicle’s cigarette-lighter

socket.

MAINTENANCE

Your Optimus AMX-10 Stereo Amplified Speakers are an example of superior de-

sign and craftsmanship. The following suggestions will help you care for the speak-

ers so you can enjoy them for years.

Keep the speakers dry. If they get wet, wipe them dry immediately.

Liquids might contain minerals that can corrode the electronic cir-

cuits.

Use and store the speakers only in normal temperature environ-

ments. Temperature extremes can shorten the life of electronic de-

vices, damage batteries, and distort or melt plastic parts.

Keep the speakers away from dust and dirt, which can cause prema-

ture wear of parts.

Handle the speakers gently and carefully. Dropping them can dam-

age the circuit boards and can cause the speakers to work improper-

ly.

Wipe the speakers with a damp cloth occasionally to keep them look-

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

tergents to clean the speakers.

Modifying or tampering with the speakers’ internal components can cause a mal-

function and might invalidate the warranty. If your speakers are not performing as

they should, take them to your RadioShack store for assistance.
