Maintaining Your Lifestyle ® Stereo Amplifier
Cleaning the amplifier
CAUTION: Disconnect the power cord from the AC outlet before cleaning.
The amplifier, which is designed only for indoor use, may become dusty over time. To clean
the amplifier, use only a soft, dry cloth to remove dust from the outside of the enclosure. You
may use a brush attachment on a vacuum cleaner to clean the hard-to-reach areas. DO NOT
use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives.
Protecting outdoor wiring
Although some Bose ® speakers are designed and tested to stand up to outdoor weather con-
ditions, the bare ends of the speaker wire can be affected by exposure to the elements. This
is especially true of salt water exposure.
You may use a silicone caulking material, such as RTV adhesive, to protect speaker wire con-
nections. It is commonly available at hardware stores. If you do use caulking, apply it only
after the wires are connected and the knobs tightened down. Check the caulking annually,
and re-apply as needed.
Troubleshooting
If you have a problem operating your Lifestyle ® system after installing the Lifestyle ® stereo
amplifier, follow the guidelines below. For additional help, see the troubleshooting information
in your system owner’s guide. If the problem still exists, contact your Bose dealer to arrange
for service, or contact Bose Customer Service. Refer to the address list enclosed in the prod-
uct packaging for correct phone numbers.
Problem What to do
Neither speaker
plays • Make sure the Lifestyle ® media/music center and the amplifier are plugged in and turned on.
• Make sure the plugs are inserted fully and the outlets are in working order.
• Be sure a music source is selected (AM, FM, CD, AUX, etc.). If CD or AUX is selected, check to be sure there
is a CD in the player or the source connected to AUX is turned on.
• If using a Model 20 music center, make sure the audio input cable is inserted into SPEAKER ZONE 2.
• If using a Model 5 music center for home theater (Lifestyle
® 12 or Lifestyle ® 8 systems), make sure the
amplifier audio input cable is plugged into the FIXED OUTPUT jacks on the music center. (Then the speaker
output cable to the Acoustimass
® module should be connected to the piggyback jacks on the audio input
cable.)
• Disconnect any headphones.
• Make sure the remote control switch settings are correct.
Only one speaker
plays • Check the wires connected to the speaker that does not play.
• Make sure the wires are in good condition and are firmly connected at both ends.
• See “Connecting speakers to your Lifestyle
® stereo amplifier” on page 21.
One speaker still
does not play • Disconnect the wires from that speaker and the amplifier. Disconnect the other cable from its speaker, and
connect that end of the cable to the speaker that does not play. If the speaker still does not play, the prob-
lem is in the speaker. If the speaker now plays, continue checking for the source of the problem.
• Disconnect the same cable from the amplifier. Connect it to the other outputs on the amplifier. If the speaker
plays, the problem is in the original cable that was connected to that speaker. If the speaker does not play,
the problem is in that channel of the amplifier.
Right and left stereo
channels are heard
on the wrong speak-
ers. • Check the speaker cable connections to be sure the cable connected to the SPEAKER OUTPUTS L at the
amplifier are connected at the other end to the speaker on the left in your listening area.
• Check the speaker cable connections to be sure the cable connected to the SPEAKER OUTPUTS R at the
amplifier are connected at the other end to the speaker on the right in your listening area.
