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
g
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.
