®

tion of the card and mail it to Bose.
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 problem 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.
Bass or treble is
weak • Check the speaker wire connections. Make sure the wires are con to + and
– to –.
• See “Connecting speakers to your Lifestyle ® stereo amplifier” on page 14.
Interference • Make sure the speaker wires are firmly inserted in the terminals on the back of the
speaker and on the amplifier rear panel. Check to be sure no wires are touching
across terminals.
• See “Connecting speakers to your Lifestyle ® stereo amplifier” on page 14.
Remote does
not adjust the
volume • Be sure the 1/8” mini-plug is firmly inserted in the SYSTEM CONTROL 2 jack.
• If you are using an RC-20 or RC-5 remote control, make sure the remote control
switch settings are correct.
Volume
suddenly
decreases • Lower the volume setting to see if the level returns to normal. If so, the sudden loss of
volume was an intentional action of the amplifier’s overload protection feature. This
engages automatically if the volume is set too high and is overdriving the speakers.
Choosing a lower setting should ensure continuous, even volume.
Zone 2 does not
work at all • If you are using a Lifestyle ® DVD system, the stereo amplifier will not work unless
“Zone 2 Protocol” in the system settings menu is set to “Legacy”. For more informa-
tion, consult your Lifestyle
® DVD system’s owners guide.
