Your HTS-105 Home Theater System includes the STAV­3770 receiver (RadioShack 31-3042, with its owner’s man­ual and accessories), two front speakers, two surround­sound (rear) spe akers, one center-channel spea ker, and
one amplified subwoofer. All you need to add to have a

source (stereo Hi-Fi VCR or DVD/LD player) and a TV.

For receiver instructions and the HTS-105’s warranty, refer

the next few pages only cover basic home theater and
speaker connections, and how to adjust the subwoofer
controls. Before mak ing any c onn ect ion s, see “Positioning

Caring for Your Speakers

• Use a polishing cloth or dr y cloth to w ipe 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 in cludes all speak er 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 speak­er wire pair). Use these colors as a guide to help you prop­erly connect the speakers. (For subwoofer connection,
use the supplied patch cable with phono plugs on both
ends. Phasing is au tomatic.) For easy identi fication, your
speakers are labeled
