HTS-102 Home Theater System
Your HTS-102 home theater system includes the STAV-
3770 receiver (RadioShack 31-3042, with its owner’s man-
ual and accessories), two front speakers, two surround-
sound (rear) speakers, one center speaker, and one sub-
woofer. All you need to add to have a complete home the-
ater system are an audio/video input source (stereo Hi-Fi
VCR or DVD/LD player) and a TV.
Caring for Your Speakers
• Use a polishing cloth or dry cloth to wipe off dust and
dirt.
• If the cabinet is very dirty, wipe it with a soft cloth
dipped in a neutral cleanser diluted with water, then
wipe again with a dry cloth. Do not use furniture wax
or cleaners.
For receiver instructions and the HTS-102’s warranty, refer
to the STAV-3770 Owner’s Manual. The instructions on
the next few pages only cover basic home theater and
speaker connections. Before making any connections, see
“Positioning Speakers” on Page 5 of the STAV-3770 Own-
er’s Manual to choose the best locations for your speak-
ers.
• Never use thinner, benzene, insecticide sprays, or
other chemicals on or near the cabinets.
• Never use a vacuum cleaner to clean the grille cloth.
Connecting Speakers
Center Speaker
TV
Your HTS-102 system includes all speaker wires required
for speaker connections. Each speaker wire consists of
two conductors (individual wires) encased in insulation
and is color-coded so you can identify each conductor (the
color mark is on only one of the conductors in each speak-
er wire pair). Use these colors as a guide to help you prop-
erly connect the speakers.

If the supplied speaker wires are too short for your con-
nections, you can purchase additional wire at your local
RadioShack store. Use 16-gauge (or larger) speaker wire
for all speaker connections.

Wall Mounting the Speakers
To mount the speakers on a wall, you need wood screws with heads that fit into the keyhole slot on the back of each speak-
er. Make sure the wall surface and screws you use are appropriate for the weight of the speakers. Keep in mind that the
speaker’s vibration will affect the surface, so we do not recommend mounting on plywood boards or other soft-surface
walls.
1
Drill a hole and thread a screw into the wall, letting the head extend about /4 inch (6 mm) from the wall. Align the keyhole
slot with the mounting screw and slide the speaker downward to secure it.
