Your HTS-105 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-channel speaker, and
one amplified subwoofer. All you need to add to have a
complete home theater system are an audio/video input
source (stereo Hi-Fi VCR or DVD/LD player) and a TV.
For receiver instructions and the HTS-105’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, and how to adjust the subwoofer
controls. Before making any connections, see “Positioning
Speakers” in the STAV-3770 Owner’s Manual to choose
the best locations for your speakers.

Supplied Accessories
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.
• 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
Your HTS-105 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. (For subwoofer connection,
use the supplied patch cable with phono plugs on both
ends. Phasing is automatic.) For easy identification, your
speakers are labeled
FRONT
and
REAR
.
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.
When connecting each conductor to a speaker terminal,
hold down the terminal lever, insert the conductor’s end
into the small hole, and release the terminal lever to se-
cure the conductor.
When connecting each conductor to the receiver, press
open the terminal lever, insert the conductor’s end into the
small hole, and press the lever closed to secure the con-
ductor.
Notes:
• Be sure you connect the receiver’s right and left posi-
tive (+) and negative (–) terminals to the speaker’s
corresponding right and left positive (+) and negative
(–) terminals.
• Do not connect two pairs of speakers to a single set of
terminals.
• Surround speakers generally sound best if you posi-
tion them above ear level.
