5.2.5 Digital Customer Service Mode (DCSM)
Purpose
The Digital Customer Service Mode shows error codes and
information on the IBO Zapper module (DVB reception part)
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 (called "Setup").
2. Activate the "Information" sub menu (via the "down" and
"right" cursor buttons).
3. In the "Information" sub menu, press the following key
sequence on the remote control to activate the DCSM:
"GREEN RED YELLOW 9 7 5 9" (do not allow the display
to time out between entries while keying this sequence).
Then, the "Service menu" will appear (see figures below).
Alternative method to activate DCSM: press key sequence
"123654" on the remote control transmitter while in digital mode
(do not allow the display to time out between entries while
keying the sequence). Then, the "Service menu" will appear
