Exchange of micro-processor module PCB3
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 deactivated from the factory, it is up to the user to
activate it.
If the theft protection is activated, and the product has been without mains for
15-30 minutes, the user will be asked to enter the 4 digit PIN-code.
Before the product is handed in to service it is a good idea to ask the customer to
deactivate the theft protection.
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/registering the exchanged modules to the Customer's
product. The 12 hours are only running when the product is connected to mains!
If the customer's PIN-code or Master-code is entered the exchanged modules will be
named/registered to the product. Registration of the modules cannot be changed.
The service code must be entered when a source is selected and the product asks
for the PIN-code "PIN _ _ _ _" press down the
seconds and the display now writes "PIN _ _ _ _ _", press
digit, press OK (Keyboard) to accept digit.
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 at Bang & Olufsen.
When a source is selected and the product asks for the PIN-code "PIN _ _ _ _"
p
press down the
button (Keyboard) for three seconds and the display asks for 5
digits instead of 4: "PIN _ _ _ _ _" ; enter the 5 digit Master code. Press
(Keyboard) to select digit, press OK (Keyboard) to accept digit.
The Master code is ordered by sending a request either via the Retail System or on
the Master code formula, if non of these options are available please contact Bang &
Olufsen.
When exchanging PCB3 remember to insert the EEPROM from the defective
module, because it contains valuable data (serial no., type no., PIN-code etc.).
The data is not transferred to the new module until you have been in contact with
the theft protection or after 12 hours connected with mains. This means that you
can try out a new PCB3 without transferring the products serial no. etc.
Note !
When the serial no. has been transferred to the micro-processor it can only be
used for this specifi c product. Otherwise the module must go back to Bang &
Olufsen's module repair department as an exchange module to be erased again.
If the product functions are OK the theft protection is also OK; there is no need for
testing the functionality of the theft protection.
When the product is connected to mains, wait 20-30 sec. before operating.
All addresses in ML hav to be updated after disconnecting mains voltage.
