5.2.3 Customer Service Mode (CSM)
Purpose
When a customer is having problems with his TV-set, he can
call his dealer. The service technician can than ask the
customer to activate the CSM, in order to identify the status of
the set. Now, the service technician can judge the severness of
the complaint. In many cases, he can advise the customer how
to solve the problem, or he can decide if it is necessary to visit
the customer.
The CSM is a read only mode, therefore modifications in this
mode are not possible.
