HOW TO SERVICE

Big efforts have been made to introduce the highest quality and a low call rate.
Therefore this product is suitable for the new Service Strategy which benefi ts the
customer. In a service situation where there is an electrical fault in a BeoLab 2, the
fault can be removed during one visit to the customer’s home if you bring a Back­up suitcase with you. If it is a mechanical fault, the particular part can be replaced
in the customer’s home.
When the necessary part(s) arrive from service stock, the visit to the customer’s
home can be arranged.

Front line service

The BeoLab 2 must be serviced in the customer’s home when dealing with electrical
faulty or the exchange of mechanical parts. In this way, you avoid having to

transport the heavy subwoofer (18kg) back and forth from the customer (box size:
L 310 x W 260 x H 315 mm).
In the customer’s home, it is possible to exchange the driver and slave units, the
electrical chassis or transformer, as well as exchange the cabinet and foot.
Replacement of the cabinet can be done easily at the customer’s home as it
contains all the necessary parts. Only the loudspeaker units, the electrical chassis
and the transformer must be put into the new cabinet.

Electrical parts

For front line service we offer a Back-up suitcase (also applies to BeoLab 1). All the
needed electrical parts are located in the Back-up suitcase (loudspeaker units and
electronics).
That means the BeoLab 2 Back-up suitcase must be ordered and returned.

Service documentation

Service documentation for the BeoLab 2 is this guide (with part numbers for the
Back-up suitcase and mechanical parts) and the User’s Guide.

TYPE SURVEY

To change voltage supply, e.g. when moving between two countries, it may be
necessary to order a new electrical chassis, mains trafo and mains cable.
E.g.:
Moving from EU (type 6861) to Japan (type 6864); order 3 part nos. for Japan type
6864 (electrical chassis - mains trafo - mains cable).

TYPENÜBERSICHT

Zur Änderung der Spannungsversorgung, z.B. beim Umzug in ein anderes Land,
kann die Bestellung eines neuen elektrischen Chassis, Netztrafos und Netzkabels
erforderlich sein.
D.h.:
Beim Umzug aus der EU (Typ 6861) nach Japan (Typ 6864) müssen drei Posten für
den japanischen Typ 6864 bestellt werden (elektrisches Chassis - Netztrafo - Netzkabel).

RECHERCHE DE TYPE

Pour changer de tension d’alimentation, par ex. en déménageant vers un autre
pays, il peut être nécessaire de commander un nouveau châssis électrique, un
nouveau transformateur secteur et un nouveau câble secteur.
Exemple :
Pour un déménagement de l’Union européenne (type 6861) vers le Japon (type

6864), il faut commander 3 références correspondant au type japonais 6864
(châssis électrique - transformateur secteur - câble secteur).

ESAME TIPOLOGICO

Per cambiare l’alimentazione elettrica, per esempio in occasione di uno spostamento
all’estero, può essere necessario ordinare un nuovo quadro elettrico, trafo di
alimentazione e cavo di alimentazione.
Per esempio.:
In caso di spostamento da un paese dell’UE (tipo 6861) al Giappone (tipo 6864),
ordinare 3 parti per il Giappone tipo 6864 (quadro elettrico - trafo di alimentazione ­cavo di alimentazione).

INSPECCIÓN DEL MODELO

Por ejemplo cuando se viaja entre dos países, puede que haya que solicitar un
chasis eléctrico, un transformador y un cable de red nuevos para cambiar la fuente
de alimentación.
Por ejemplo:
Si se viaja de Europa (modelo 6861) a Japón (modelo 6864), hay que solicitar los
3 números de referencia para el modelo 6864 de Japón (chasis eléctrico ­transformador de red - cable de red).

TYPE OVERSIGT

For at skifte spændingsforsyning, f.eks. ved fl ytning til et andet land, kan det være
nødvendigt at bestille et nyt el-chassis, en ny nettransformer og en ny netledning.
Eksempel:
Ved fl ytning fra EU (type 6861) til Japan (type 6864) bestilles 3 varenumre til den
japanske type 6864 (el-chassis - nettransformer - netledning).

TYPE-OVERZICHT

Om een voedingseenheid te vervangen, bijv. bij een verhuizing naar een ander land,
is het soms nodig om een nieuw elektrisch chassis, een nieuwe transformator en
een nieuw netsnoer te bestellen.
Bijvoorbeeld:
Bij een verhuizing vanuit de Europese Unie (type 6861) naar Japan (type 6864)
bestelt u voor het Japanse type 6864 drie artikelnummers (elektrisch chassis,
transformator en netsnoer).

BRIEF OPERATION GUIDE

Setting the POSITION switch

Use the POSITION switch is to ensure that the bass response suits the placement of
BeoLab 2, and thus the surroundings.
Which switch setting to choose depends on the distance from BeoLab 2 to the
walls and corners of the room.

The POSITION switch has three settings:
CORNER: Use this setting if BeoLab 2 is placed in a corner – shown by the dark
grey areas in the illustration.
WALL: Use this setting if BeoLab 2 is placed closer than approx. 50 cm (20”) to a
wall, and no closer to a corner than approx. 150 cm (60”) – shown by the medium
grey areas along the walls in the illustration.
FREE: Use this setting if BeoLab 2 is placed more than approx. 50 cm (20”) from the
wall – shown by the light grey area in the illustration.

Never place BeoLab 2 behind your listening position. We recommend that you avoid placing any of

your loudspeakers in the area inside the thin dotted line.
