5.2.3
Customer Service Mode (CSM)
Purpose
When a customer is having problems with his TV-set, he can
call his dealer or the Philips helpdesk (P3C). 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 severity 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.
How to Activate CSM
Use one of the following methods:
•
Press the "MUTE" button on the RC-transmitter
simultaneously with any key on the TV for at least 4
seconds.
•
Key in the code "123654" via the standard RC transmitter.
Notes:
•
Activation of the CSM is only possible if there is no (user)
menu on the screen!
•
During CSM, sound volume is set to 25% of the scale,
"Smart Sound" is set to "Theatre" mode, and "Smart
Picture" is set to "Rich/Movies" mode temporarily to ensure
a good picture and sound of the working set. After leaving
CSM, the original settings are restored.
How to Navigate
By means of the "CURSOR-DOWN/UP" knob on the RC-
transmitter, you can navigate through the menus.
