INTRODUCTION
Your Optimus AMX-10 Stereo Amplified Speakers are specially designed
for use with computer multimedia systems. The speakers’ magnetic shield
allows you to place them next to your
PC’s monitor without causing picture
distortion.
The speakers also transform your portable CD player or personal cassette
player into a complete music system.
The speakers are com pat ible with any
audio source that has a
1
/8-inch stereo
headphone or line out jack.

POWER SOURCES
You can power your speakers from internal batteries, standard AC power,
or vehicle battery power.

battery compartment cover, then
lift off the cover.
2. Put four batteries into each
speaker’s compartment, as indicated by the polarity symbols (+
