The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.

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 loudspeakers 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 firmly.

You can clean the front cloth with a vacuum cleaner with a brush nozzle, and set to the lowest level. Clean the cooling fins 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 sys tem off again the loudspeakers also switch to standby.
If the loud speakers are connected to a non Bang & Olufsen system they switch on when a signal is received from the sys tem. They switch off a few minutes after the signal has disappeared.

Never use alcohol or other solvents to clean any parts of the loudspeaker!

NOTE! Prolonged listening at high volume levels may cause hearing damage.

Set up the loudspeakers

We recommend that you follow this procedure:

• Disconnect your system from the mains supply.
• Place the loud speakers according to the guidelines on these two pages. If you wish to hang the loud speakers on the wall, refer to 'Wall bracket'. If you have chosen one of the optional accessories, refer to the Guide enclosed with the accessory.
• Connect the loud speakers and set the LINE–L–R switch on each loudspeaker as explained in 'Cable connections'.
• Connect the entire system to the mains again.

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

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 loud speakers 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 loud speakers.
• Do not place any items on top of the loud speakers.
• Do not place the loud speakers enclosed, for example, in a small book case.
• When the loud speakers are placed in an upright position, make sure that the indicator light is at the base.
• When you place the loud speakers try to 'aim' the front cloth towards your preferred listening position.

The wall bracket

The wall brackets can be used to fasten the loud speakers in either a vertical or horizon tal position on a wall. They may also be used to fasten the loudspeakers to the ceiling.

To support the weight of the loudspeaker, 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' for further information.

Special notice about light partition walls and gypsum ceilings
Light partition walls and ceilings are of ten 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 loud speaker. If you intend to hang the loud speaker on such a wall or ceiling, the wall bracket must be fastened to a stud.

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 loudspeakers standing on a level surface, we recommend that you attach the enclosed rubber pads to the bottom plate of each loud speaker – in order to protect both your furniture and the loud speakers 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 specific information about the sockets on your system, refer to the Guide enclosed with your system.

Connection panel

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

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 loud speakers to a non Bang & Olufsen system.

POWER LINK 1–2 sockets
These socket are used for connection to a Bang & Olufsen system. However, if the switch marked LINE–L–R is set to LINE, you may use one of the sockets to connect the loudspeaker to a non Bang & Olufsen system.

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

Connection to Bang & Oluf sen systems

Use a Power Link cable to connect 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

Use a special adapter with an ordinary phono/RCA plug in one end, and a DIN plug in the other ('Cable for line signal' – optional accessory, available from your Bang & Olufsen retailer).

Set the switch to LINE.

Power Link connections

These connections carry both the right and left sound signals. Therefore, you can:

1. Run a Power Link cable from your Bang & Olufsen system directly to each loudspeaker.
   
   Or
2. Run a Power Link cable from your Bang & Olufsen system to the first 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 loud speaker, in the preferred position. Tighten the two screws (D) securely!
• Hold up the loud speaker where you want to place it on the wall, and mark up the outline of the bracket. Use the bracket (A) as a tem plate to mark up where to drill the holes.
• Fasten the bracket (A) to the wall through the holes (E), and hang the loud speaker onto the four hooks.
  

The lock will engage and thus secure the two parts. You can release the lock with a small screwdriver through the hole (C).

The placement of the bracket on the rear of the loud speaker deter mines the angle between the loud speaker and the wall.

Light partition walls

If you intend to hang the loudspeaker 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 posi tion, two screws through the holes (E) will suffice.
