BeoCenter 2 Service Profile

BeoCenter 2 is an integrated system designed for audio or audio/video home-entertainment setups offering DVD, CD audio and radio. It will take its main position in the main room where its prime functionality is to distribute picture and sound to a AV system. The product will also be able to distribute its sources through the Beolink system to other rooms. BeoCenter 2 can play back DVD video and distribute radio simultaneously.

BeoCenter 2 will be able to play an important role together with BeoVisions, acting as a normal audio master with the facility of exporting its DVD video signal to the TV.

Servicing the units:
BeoCenter 2 is a two piece setup: a Master unit and a separate Socket unit interconnected by one cable only which holds supply voltages and video and audio signals. The Master unit is operation panel, DVD loader and display and the Socket unit holds all external cable connections to the surrounding products and mains. Both products have been built up by separate modules depending on the functionality which makes it easier to perform fault-finding and on-site service.

The Master unit has just one variant for all markets. When connected to the separate Socket unit and 'DVD' is pressed, the unit is dedicated to the Socket unit's DVD region code. The DVD region code can be changed if necessary using the Service Tool (3658949).
The Socket Panel has separate type numbers for each market due to country approvals and DVD region code.
The Socket Panel includes the necessary cable for connecting the two parts as well as a mains lead. In some variants antennas and Beo4 remote control may be included.

Installation and presetting
All connections are made on the separate Socket Panel. The mains voltage is determined by the type no. of the Socket Panel. There are only two internal mains voltage settings (a jumper 60J10 p/n 7210406) on the Switch Mode Power Supply, 85 - 132V and 187 - 264V AC). Automatic adaptation to mains frequency 50 or 60Hz. The FM/AM tuning and the DVD/CD can be used directly via the close-up operation panels.


The Service menu on the Master unit is accessed by choosing the setup menu b.m.o. >> and then pressing 0 0 GO

PIN Code protection: general description:

The theft protection is a 4 digit PIN-code, of the user's own choice, which must be entered if the product has been disconnected from the mains for 15-30 min. The theft protection is always activated from the factory, it is up to the user to deactivate it, or change it to another PIN Code.

Service:

Service code
If the PIN-code is activated and the product is in a service situation, there is a possibility of 12-hours service by entering a 5 digit Service code which is 11111. This gives 12 hours of full functionality to service the product and make module changes without naming/register the exchanged modules to the Customers product. The 12 hours is only running when the product is connected to mains.

The service code must be entered when a source is selected and the product asks for the PIN-code “PIN _ _ _ _”.
Press LIST << << EXIT to get access to PIN Code, and << << << to open for Master code input.
Select the Service code digits 11111.
The display shows "PIN Code not deleted"; and the product can be used for 12 hours before going into PIN Code protection.

Master code
If the PIN-code has been forgotten (5 tries every 3 hours with mains connected), the only way to unlock the product again is by entering the 5-digit Master code. The Master code can be ordered through Bang & Olufsen. Once the code is keyed in, BeoCenter 2 becomes operational again and the PIN code system is deactivated.

Press LIST << << EXIT to get access to PIN Code, and << << << to open for Master code input.
Enter the Master code
"PIN Code deleted" appears in the display indicating that the PIN code system is deactivated and a new PIN Code can be chosen.

Exchange of PCB6 (Main PCB)
If the µPH8 on the Socket unit is exchanged this can be undertaken without any problems. The exchange module contains a “digital exchange-code” which make it able to adapt the identity of the product. The data will be transferred after 12-hours or if the PIN Code protection is operated unless with the Service code. This means that the exchange module can be tested for for 12 hours before it adapts the identity of the product and in a locked situation you can unlock the product with the Service code without naming the module to the product.
