How to Navigate
As this mode is read only, there is not much to navigate. To
switch to other modes, use one of the following methods:
•
Command MENU from the user remote will enter the
normal user menu (brightness, contrast, colour, etc...) with
“SDM” OSD remaining, and pressing MENU key again will
return to the last status of SDM again.
•
To prevent the OSD from interfering with measurements in
SDM, command “OSD” or “i+” (“STATUS” or “INFO” for
NAFTA and LATAM) from the user remote will toggle the
OSD “on/off” with “SDM” OSD remaining always “on”.
•
Press the following key sequence on the remote control
transmitter: “062596” directly followed by the OK button to
switch to SAM (do not allow the display to time out between
entries while keying the sequence). Remarks: new RC will
not have I+ button, but function still remains.
How to Exit SDM
•
Switch the set to Stand-by, by pressing the standby button
on the remote control transmitter or on the television set.

Via a standard customer RC-transmitter: key
in “00”-sequence.
