Service tool
To service BeoLab 5 a LabTop with the Bang & Olufsen service tool application is
needed. With the “Service Tool” it is possible to read error codes, service counters
and product ID and to save them in a file. (The service tool is downloaded from
the Retail System).
It is also possible to read data from the EEPROM and write data to the EEPROM.
This is necessary when a driver unit or a EEPROM has to be replaced. Test functions
and software update are also possible.
Replacement of driver
If it should be necessary to replace one of the driver units there are several things
to be aware of. For service purposes each driver is measured separately and the
result of this measurement is stored in a server at Bang & Olufsen together with a
specific serial number for each driver.
A label is placed on the driver with its serial number. In BeoLab 5 the data
belonging to drivers are stored in a EEPROM, placed in a socket on the chassis. In
a repair situation it is necessary to be able to write the data - belonging to the
actually driver to the EEPROM. This is done with a LapTop with the Bang & Olufsen
Service Tool application.
All data for the drivers will be available in the Retail System.
The procedure:
Access the Retail System and download driver data for BeoLab 5. Data for all
existing drivers will be downloaded to the LapTop. This is done to be sure that the
technicians have access to the correct data.
When the technician has replaced a defective driver in BeoLab 5 he must check
the serial number of the new driver - written on a label, placed on the driver.
Connect the cable between the LapTop and BeoLab 5 and start the Service Tool
and access “BeoLab 5” in the menu.
Choose the function for writing to the EEPROM and key in the serial number. The
application will automatically find the correct data for the actual driver. Press the
button for write and the data will be transferred to BeoLab 5. An extra label with
the serial number is supplied with the driver. This must be placed on the cabinet.
