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-

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.
