5.1
Service Modes
5.1.1
Digital Customer Service Mode (DCSM)
Purpose
The Digital Customer Service Mode shows error codes and
information on the IBO Zapper module operation settings. The
call centre can instruct the customer to activate DCSM by
telephone and read off the information displayed. This helps
the call centre to diagnose problems and failures in the IBO
Zapper module before making a service call.
The DCSM is a read-only mode; therefore, modifications are
not possible in this mode.
How to Activate
To activate the DCSM, put the television in its digital mode (via
the A/D button on the remote control).
1.
Press the “Digital” Menu button on the remote control to
activate the digital user menu (“Setup”).
2.
Activate the “Information” sub menu (via the “down” and
“right” cursor buttons).
3.
In the “Information” sub menu, press the following buttons
on the remote control to activate the DCSM:
“
