Bang & Olufsen BeoLab 11 - User Guide - Manual (Page 3)

Daily use
When you have finished setting
up the subwoofer as described
on the following pages,
connect the entire system to
the mains supply. The indicator
lights up in red, indicating that
the subwoofer is in standby,
ready to be used. The
subwoofer is designed to be
left in this standby mode when
not in use.
NOTE! The subwoofer is
designed to protect itself if the
active speaker unit becomes
overheated. The subwoofer
protection circuit may become
active after a period of playing
at a high volume level.
Switching on and off – indicator
When you switch on your Bang &
Olufsen system, the subwoofer
switches on simultaneously. The red
standby indicator light turns green,
indicating that the subwoofer is
switched on.
When you switch off your system,
or mute the sound, the red indicator
light appears immediately, indicating
that the subwoofer is not in use.
Subwoofer protection
If the active speaker unit becomes
over heated, the subwoofer will
instantly reduce the sound level.
Once the situation has stabilised,
the sound level is slowly returned to
normal. If the subwoofer is played
constantly at a very high volume
level, it will eventually mute the
sound completely.
Should the subwoofer mute the
sound, the indicator light turns
orange.
To restore the sound:
> Disconnect the subwoofer from
the mains.
> Allow the active speaker unit
time to cool off.
> Reconnect the subwoofer to the
mains.
Should the problem persist,
contact your Bang & Olufsen
retailer.
Cleaning the subwoofer
Wipe dust off the surfaces using a
dry, soft cloth. If necessary, remove
stains or dirt with a soft, damp
cloth and a solution of water and
mild detergent such as washing-up
liquid.
Never use alcohol or other solvents
to clean any part of the subwoofer!
