How to service
Front line service
BeoLab 3 must be serviced in the customers home when it comes to electrical
symptoms or exchange of mechanical parts. In this way you avoid having to make
more than one visit and using minimum of time on the case, all for the benefit of
the customer.
The loudspeaker dimensions are H-215mm, W-135mm, L-162mm, 2,55 kg and
the carbon box for two loudspeakers are H-350mm, B-360mm, D-380mm, 6,5 kg.
In the customers house it is possible to replace :
The electrical parts :
The loudspeaker units
The passive radiators
The complete main chassis
The standby LED PCB
The mechanical parts :
The lens for the tweeter
The cabinet
The foot
A sound level adjustment procedure is necessary when replacing one or more
loudspeaker units, or replacing the main chassis. This is done easily be means of
click potentiometers.
Replacements of the cabinet can be done at the customers as it consist of a
complete cabinet with gaskets and other materials there are needed when
exchanging the complete cabinet. Only the lens, the loudspeaker units, the main
chassis and the foot must be put onto the new cabinet.
Back-up Suitcase
The service Back-up Suitcase will contain all needed electrical parts, that is needed
to service a failing speaker. All mechanical parts must be ordered separately from
B&O Struer DK. All the needed tools and a Service Center Repair Guide will be
found in the suitcase.
Converting mains voltage supply
If it is necessary to change voltage supply, e.g. when moving between two
countries, this can be done easily in the BeoLab 3 speakers (on module 01 – P504).
You will only need to mount/remove a jumper. The fuse will be a global type, so
here is no need for replacement. Remember to order new mains cables.
