STS 600 61/2-Inch Two-Way Mini Tower Speaker
Your Optimus STS 600 61/2-Inch Two-
Way Mini Tower Speaker is a two-way
acoustic suspension speaker that uses
a 61/2-inch vacuum-formed polypropy-
lene woofer that yields excellent low-
end response and tight, clean bass. A
/4-inch urethane-treated cloth soft
dome tweeter provides clear and natu-
ral high-frequency sound reproduction.
You need speaker wire (not sup-
Note:
plied) to connect your speaker. Please
read this entire manual before you con-
nect your speaker.

CARE AND
MAINTENANCE
1
Your Optimus STS 600 6 /2-Inch Two-
Way Mini Tower Speaker is an exam-
ple of superior design and craftsman-
ship. The following suggestions will
help you care for your speaker so you
can enjoy it for years.
4. Press the right speaker’s positive
(+) terminal tab and insert the
other bare wire end into the open-
ing. Then release the tab.
• Handle the speaker gently and
carefully. Don’t drop it!
• Use and store the speaker only in
normal temperature environments.
• To maintain the speaker cabinet’s
finish, do not let it come in contact
with water vapor, alcohol, ben-
zene, insecticide, or similar liquids.
Do not place a plastic covering on
top of the speaker, as the plastic’s
color could come off and stick to
the finish.
5. Insert the other end of the wire you
inserted into the right speaker’s
negative (–) terminal into your
amplifier/receiver’s right negative
(–) speaker terminal.
• Clean the speaker cabinet with a
soft, dry cloth.
• Never touch the speaker elements
with your hands or expose them to
excessive shocks. If they become
dented or bent, the sound distorts.
Note: For the maximum bass
response and the best perfor-
mance, be sure your speaker
wires are properly connected
according to their polarity (+ to +
and – to –).
Caution: You might permanently
damage your speaker by cleaning
it with a vacuum cleaner. Instead,
use a feather duster or a soft cloth.
6. Connect the remaining wire to the
amplifier/receiver’s right positive
(+) speaker terminal.
Modifying or tampering with the speak-
er’s internal components can cause a
malfunction and might invalidate your
speaker’s warranty. If your speaker is
not performing as it should, take it to
your local RadioShack store for assis-
tance.
7. Repeat this process to connect
another speaker to your amplifier/
receiver’s left speaker terminals.
