How to service
Strategy
The product is to be serviced in the customer’s home.
The repair involves replacement of the module(s). The replaced modules must be
returned for repair at the Bang & Olufsen Module Repair department. Error codes
as well as an adequate fault description must be returned with each replaced part.
For this purpose, use the Module Repair form or the form in the Retail System
under Exchange Module.
To help the Bang & Olufsen Module Repair department it is very important to
answer the following questions:
1. Which products are in the setup?
2. Which software versions are used in these products?
3. How are the products linked together?
4. What happens in the actual situation?
Fault explanation and demonstration
Before troubleshooting is initiated, let the customer demonstrate the fault, if
possible.
Preparations before service
Always remember to download the latest version of the Service Manual from
BeoWise. Also remember, before servicing the product, to update the latest
version of the software in the Master Link Gateway to ensure optimum conditions.
Servicing
The Master Link Gateway must be serviced by qualified technical personnel only.
If it is not possible to determine the location of the fault or if replacing spare parts
does not clear the fault, please contact your national Service Centre for technical
support.
Handling
Like any other electronic equipment, this product must be handled with care.
Particularly the PCB’s inside Master Link Gateway which contains electrostatic
sensitive devices (ESD), and must therefore be handled carefully to prevent
damaging.

Module require an adjustment after replacement as the serial number has to be
transferred into the new module. Furthermore, it is necessary to transfer the
customer data (backup data from the customer setup made ealier) into the new
