Daily use
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, lint-free
cloth which you have dipped in
lukewarm water and wrung firmly.
Never use alcohol or other solvents to
clean any parts of the loudspeaker!
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
loudspeakers 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
loudspeakers 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.
