Bang & Olufsen BeoLab 9, Manual

Page: 4 / 12

Daily use
When you have finished setting up
the loudspeakers as described on
the following pages, connect the
entire system to the mains supply.
The indicators light up in red,
indicating that the loud speakers
are in standby, ready to be used.
The loudspeakers are designed to
be left in standby mode when not
in use.
Switching on and off
When you switch on your system, the loud-
speakers switch on simultaneously, and the
indicator lights turn green. When you switch
the system off again the loud speakers also
switch to standby.
Cleaning the loudspeaker
Clean dusty surfaces using a dry, soft cloth.
If necessary, remove grease stains or persistent
dirt with a soft, lint-free cloth which you have
dipped in lukewarm water and wrung firmly.
Never use a vacuum cleaner to clean the
exposed speaker membrane in the acoustic
lens. However, the front cloth may be cleaned
with a vacuum cleaner with a brush nozzle,
and set to the lowest level.
Never use alcohol or other solvents to clean any
parts of the loudspeaker!
Loudspeaker protection
Each loud speaker is equipped with a thermal
protection system which prevents damage from
overheating. If an error occurs – or the speaker
units become overheated – the system auto-
matically switches the loud speaker to standby,
and the indicator light turns yellow.
To restore the sound:
> Disconnect the loudspeaker from the mains
supply.
> Allow the system time to reset or cool down
(approximately 3–5 minutes).
> Reconnect the loud speaker to the mains supply.
Should the problem persist, contact your
Bang & Olufsen retailer.
