CARE AND
MAINTENANCE
Your Optimus STS 800 8-Inch Three-
Way Tower Speaker is an example of
superior design and craftsmanship.
The following suggestions will help you
care for your speaker so you can enjoy
it for years.
• 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.
4. Press the right speaker’s positive
(+) terminal tab and insert the
other bare wire end into the open-
ing. Then release the tab.
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.
Caution: You might permanently
damage your speaker by cleaning
it with a vacuum cleaner. Instead,
use a feather duster or a soft cloth.
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 –).
• Never touch the speaker elements
with your hands or expose them to
excessive shocks. If they become
dented or bent, the sound distorts.
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.
