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.

Set up the loudspeakers
We recommend that you follow
this procedure:
– Disconnect your system from the
mains.
– Connect the loudspeakers and
set the LINE IN MODE switch on
each loudspeaker as explained in
‘Cable connections’ (pp. 6–7).
– Connect the entire system to the
mains again.
The loudspeaker must be placed
standing upright on its base, or
fastened to one of the optional
accessories. Make the connections,
and set the switch before you
fasten the loudspeaker to one of the
accessories.
Cautions
– Make sure that the loudspeakers
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
loudspeakers. Leave such
operations to qualified service
personnel! The speaker panels,
however, may be removed for
cleaning.
– The loudspeaker 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 loudspeaker
enclosed in, for example, a small
bookcase. Leave a minimum of
20 cm (8") free space at the sides,
and never place anything directly
in front of the loudspeaker.
– Do not block the sound emitting
from the bass reflex port at the
bottom of the loudspeaker.
– Place the loudspeaker with its
front (the Bang & Olufsen name
plate) facing your favourite
listening position.

Loudspeaker front and side
panels
Each loudspeaker is equipped with
one front panel and two side panels.
These panels are fastened to the
loudspeaker with three small pegs
on the rear. The front panel is
marked with a Bang & Olufsen
name plate.
To remove the panels, for example
for cleaning, just pry the three pegs
in each panel free of the
corresponding holes (A–B) in the
loudspeaker. Fasten the panels again
by inserting the three pegs into the
corresponding holes in the front
and the sides of the loudspeaker.
Note: The product identification
and CE labels are placed on the
loudspeaker body behind the side
panels.

Cable connections
The loudspeakers are intended
for use with a personal computer.
They may also be used with
non-Bang & Olufsen audio
or video systems.
About the LINE IN MODE
switch …
The switch has two settings: ON
and AUTO. We recommend that
you set the switch to the same
position on each loudspeaker.
When set to ON, the loudspeakers
will not automatically switch to
standby when the sound signal
disappears. In this case, we
recommend that you switch off at
the mains supply, when not using
the system. When set to AUTO, the
loudspeakers automatically switch
on when you switch on the system.
When you switch off the system,
the loudspeakers will, after a few
minutes, switch to standby.
Connection to personal
computers
Use the enclosed connector to
connect the computer sound card
output to each of the loudspeakers.
As the sound signal from a computer
may vary (not constantly on),
we recommend that you set the
LINE IN MODE switch to ON. This
will prevent the loudspeakers from
switching off and on every few
minutes.
Connection to audio or video
systems
Connect the system to the LINE IN
socket on each loudspeaker (mini-
jack – mono).
Set the LINE IN MODE switch to
AUTO.

The sockets and the switch are
located in the base of each
loudspeaker.

LINE IN connections: Output
from computer sound cards often
carry both the left and right sound
channels in one socket. Therefore,
use the enclosed connector when
connecting the loudspeakers to a
personal computer (fig 1). Connect
the plug marked L to the left
loudspeaker, and the plug marked
R to the right loudspeaker.
If you connect the loudspeakers to,
for example, a non-Bang & Olusen
audio or video system with separate
connections for the left and right
sound channels, make the
connections as shown in fig. 2.
Mains connections: Depending on
the type of mains supply connector
enclosed with your loudspeakers,
connect each loudspeaker to the
mains as shown in either fig. 3 or
fig. 4.
Cable Clamp: For safety reasons,
the mains lead to each loudspeaker
must be secured with the cable
clamp provided.

The European Parliament and the
Council of the European Union
have issued the Waste Electrical
and Electronic Equipment Directive.
The purpose of the Directive is the
prevention of waste of electrical
and electronic equipment, and to
promote the reuse and recycling
and other forms of recovery of
such waste. As such the Directive
concerns producers, distributors
and consumers.
The WEEE directive requires that
both manufacturers and end-
consumers dispose of electrical and
electronic equipment and parts in
an environmentally safe manner,
and that equipment and waste are
reused or recovered for their
materials or energy.
Electrical and electronic equipment
and parts must not be disposed of
with ordinary household refuse; all
electrical and electronic equipment
and parts must be collected and
disposed of separately.
Products and equipment which must
be collected for reuse, recycling
and other forms of recovery are
marked with the pictogram shown.
When disposing of electrical and
electronic equipment by use of the
collection systems available in your
country, you protect the
environment, human health and
contribute to the prudent and
rational use of natural resources.
Collecting electrical and electronic
equipment and waste prevents the
potential contamination of nature
with the hazardous substances which
may be present in electrical and
electronic products and equipment.
Your Bang & Olufsen retailer will
assist with and advise you of the
correct way of disposal in your
country.
