How to service, English 1.1

BeoLab 5 must be serviced in the customers home in terms of electrical symptoms or exhange of mechanical parts such as cloth frame, microphone or foot. In this way you avoid having to transport the heavy loudspeaker (967mm/Ø485mm,61kg) from and back to the customer. For front line service we offer a back-up suitcase. All needed electrical parts are found in the back-up suitcase (beside the transformer and lower woofer). Mechanical parts (cloth frame, foot, cabinet or alu. plates) must be ordered separately.

Service documentation for the BeoLab 5 will be a “Service Center repair guide” with part no. for the back-up suitcase, electrical and mechanical parts, User’s guides etc.

If it is necessary to change voltage supply, e.g. when moving between two countries, it is necessary to order new mains transformer and a jumper on the ICEsystem 1 PCB6 (J200 = 220-240Vac, J201 = 100-120Vac). For US/JPN the fuse F10/11 on the mains lter PCB1 must be changed from T5A to T10A also.

Type survey

E.g.: Moving from EU (type 6881) to Japan (type 6884) with a pair of BeoLab 5, order two mains transformers for type 6884, and move the jumper on the ICEsystem 1 PCB6 from J200 to J201 to adapt both speakers to the 100Vac mains voltage.

1.2 Warnings – PIN code protection, English

STATIC ELECTRICITY MAY DESTROY THE PRODUCT

Warnings

ESD

When electrical replacements or disassembly is taking place, use a ESD-mat. The internal electronic are very sensitive to static electricity.

General warnings

Wear cutton cloves to avoid any ngerprints on the product.

The aluminium surfaces on the product is very sensitive, so handling should be done with great care to avoid damage.

The mechanical limit for the driver is easily reached when the vacuum tightness in BeoLab 5 is broken.

PIN code protection

The PIN code protection system will be introduced in autumn 2003. This will be the known PIN code system, which are used in others products. The system will be mentioned in the user guide when introduced. Like on other products you will be able to use the service master code, when service is performed (11111).

PIN code protection is introduced from serial number : _________________
