Daily use
When you have nished 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 loud speakers
are designed to be left in this
standby mode when not in use.
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 rmly.
You can clean the front cloth with
a vacuum cleaner with a brush
nozzle, and set to the lowest level.
Clean the cooling ns on the rear
using a soft brush or a vacuum
cleaner.
Switching on and off
When you switch on your system,
the loudspeakers switch on
simultaneously, and the indicator
lights turn green. When you switch
the system off again the loud-
speakers also switch to standby.
If the loudspeakers are connected
to a non-Bang & Olufsen system
they switch on when a signal is
received from the system. They
switch off a few minutes after the
signal has disappeared.
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.

We recommend that you follow
this procedure:
– Disconnect your system from the
mains supply.
– Place the loudspeakers according
to the guidelines on these two
pages. If you wish to hang the
loudspeakers on the wall, refer to
‘Wall bracket’ (pp. 8–9). If you
have chosen one of the optional
accessories, refer to the Guide
enclosed with the accessory.
– Connect the loudspeakers and set
the LINE–L–R switch on each loud-
speaker as explained in ‘Cable
connections’ (pp. 6–7).
– Connect the entire system to the
mains again.
Set up the loudspeakers
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 loud-
speakers. Leave such operations
to qualied service personnel!
– The loudspeakers are designed
for indoor use in dry, domestic
environments only, and for use
within a temperature range of
10–40º C (50–105º F).
– In order not to impede ventilation
always leave at least 15 mm (0.5")
space above the loudspeakers.
– Do not place any items on top of
the loudspeakers.
– Do not place the loudspeakers
enclosed, for example, in a small
bookcase.
– When the loudspeakers are placed
in an upright position, make sure
that the indicator light is at the
base.
– When you place the loudspeakers
try to ‘aim’ the front cloth towards
your preferred listening position.

The loudspeakers must be placed standing upright on its base or fastened
to the wall or ceiling – or fastened to one of the optional accessories.

The wall bracket
The wall brackets can be used to
fasten the loudspeakers in either a
vertical or horizontal position on a
wall. They may also be used to
fasten the loudspeakers to the
ceiling.
To support the weight of the loud-
speaker, always use the correct size
and type of screws and wall anchors
– taking into account the
construction and condition of the
wall or ceiling.
Use two screws and wall anchors
each with a minimum load rating
of 10 kg (22 lbs).
Refer to ‘Wall bracket’ (pp. 8–9)
for further information.
Special notice about light
partition walls and gypsum
ceilings
Light partition walls and ceilings are
often constructed of gypsum panels
– known as drywall or wall board –
secured to studs. Gypsum is not a
satisfactory material to support the
weight of the loudspeaker. If you
intend to hang the loudspeaker on
such a wall or ceiling, the wall
bracket must be fastened to a stud.
Use screws as shown on page 9.
The screws (Ø 5 mm – 0.2") must
penetrate the gypsum and be
screwed a minimum of 25 mm (1")
into a stud.
Rubber pads: If you place the loud-
speakers standing on a level surface,
we recommend that you attach the
enclosed rubber pads to the bottom
plate of each loudspeaker – in order
to protect both your furniture and
the loudspeakers from being
scratched.

Connections
The loudspeakers can be used
with Bang & Olufsen audio,
video and link systems. They
may also be connected to
nonBang & Olufsen systems.
For specic information about
the sockets on your system, refer
to the Guide enclosed with your
system. Connection panel
LINE–L–R switch
This switch has three settings. Set
the switch to L or R when
connecting the loudspeakers to a
Bang & Olufsen system. Set the
switch to LINE when connecting
the loudspeakers to a non-Bang &
Olufsen system.
POWER LINK 1–2 sockets
These socket are used for connection
to a Bang & Olufsen system. How-
ever, if the switch marked LINE–L–R
is set to LINE, you may use one of
the sockets to connect the loud-
speaker to a non-Bang & Olufsen
system.

each loudspeaker to your system.
Set the switch to L and R (the left
and right sound channel),
respectively.
Connection to non-Bang &
Olufsen systems

The connection panel is located on
the rear of the loudspeaker.

Power Link connections: These
connections carry both the right
and left sound signals. Therefore,
you can:
1Run a Power Link cable from your
Bang & Olufsen system directly
to each loudspeaker.
Or
2Run a Power Link cable from your
Bang & Olufsen system to the
rst loudspeaker, and then run
another Power Link cable to the
next loudspeaker. This will often
help to minimise cable clutter.
For safety reasons fasten the mains
lead behind the small peg, before
running it out from the socket
compartment.
Power Link cables: The cables must
be of the type which are marked
with a triangle on the plug.
Do not use any of the old type of
Power Link cables, as this will cause
noise, and thus not give optimum
sound quality!
Mains cord: The supplied mains
cord and plug are specially
designed for the product. If you
change the plug or damage the
mains cord, you must buy another
from your Bang & Olufsen retailer!

Wall bracket
The wall bracket consists of two
main parts. The bracket (A) must
be secured to the wall, and the
bracket (B) to the rear grille of
the loud speaker:
– Separate the two parts (A– B). If
necessary, loosen the two screws
(D).
– Fasten the bracket (B) to the
loudspeaker, in the preferred
position. Tighten the two screws
(D) securely!
– Hold up the loudspeaker where
you want to place it on the wall,
and mark up the outline of the
bracket. Use the bracket (A) as a
template to mark up where to
drill the holes.
– Fasten the bracket (A) to the wall
through the holes (E), and hang
the loudspeaker onto the four
hooks.
The lock will engage and thus
secure the two parts. You can
release the lock with a small screw-
driver through the hole (C).
The placement of the bracket on the
rear of the loudspeaker determines
the angle between the loudspeaker
and the wall.

Light partition walls
If you intend to hang the loud-
speaker on a gypsum wall or ceiling,
the wall bracket must be fastened
to a stud.
If mounted in a horizontal position,
you must use three screws. Two
screws of a type for gypsum panels
through the holes (E), and one lag
screw through the centre hole of
the bracket.
If mounted in a vertical position, two
screws through the holes (E) will
sufce.
