Exchange of software EEPROM on PCB3

When exchanging the EEPROM on PCB3, the data from the micro-processor will be 

written into the EEPROM when selecting any source e.g. RADIO.

It is possible to borrow an EEPROM from another BeoSound 3000 to test if there is 

suspicion of a fault in the original EEPROM. The EEPROM will always adopt the 

data from the main micro-processor.

Exchange of both micro-processor module PCB3 and software EEPROM on PCB3

If both the micro-processor and the EEPROM need to be exchanged it is necessary 

to have them pre-programmed from Bang & Olufsen with the correct serial number, 

otherwise they will not work. 

Please contact Bang & Olufsen.
