When you have finished setting
up the loudspeakers as described
on the following pages, connect
the entire system to the mains.
Cleaning the loudspeaker
You can clean the speaker panels
with a vacuum cleaner set to the
lowest suction level. Clean the other
surfaces using a soft, lint­free cloth
which you have dipped in luke warm
water and wrung firmly.
Never use alcohol or other solvents
to clean any parts of the loud speaker!
NOTE! Prolonged listening at high
volume levels may cause hearing
damage.

Switching on and off
If you have set the LINE IN MODE
switch to AUTO, the loudspeakers
automatically switch on when they
receive an input signal – indicated
by green indicator lights. When you
switch off your system, the loud­
speakers will, after a few minutes,
automatically switch to standby –
indicated by red indicator lights.
However, if you have set the LINE IN
MODE switch to ON, the loud­
speakers are always switched on,
even when you switch off your
system.
In either setting of the LINE IN
MODE switch, the loudspeakers can
only be switched off completely by
disconnecting them from the mains
supply.
Cautions
– Make sure that the loud speakers
are placed and connected in
accordance with the instructions
in this Guide. To prevent injury,
use Bang & Olufsen approved
stands and wall brackets only!
– Do not attempt to open the
loud speakers. Leave such
operations to qualified service
personnel! The speaker panels,
how ever, may be removed for
cleaning.
Indicator light
– The loud speaker is designed for
indoor use in dry, domestic
environments only, and for use
within a temperature range of
10–40º C (50–105º F).
– For optimum sound quality, do not
place the loud speaker enclosed in,
for example, a small book case.
Leave a minimum of 20 cm (8")
free space at the sides, and never
place anything directly in front of
the loud speaker.
– Do not block the sound emitting
from the bass reflex port at the
bottom of the loud speaker.
– Place the loudspeaker with its
front (the Bang & Olufsen name
plate) facing your favourite
listening position.
