Service Default Mode (SDM)
Introduction
The Service Default Mode (SDM) is a technical aid for the service technician. The Service Default Mode (SDM)
establishes fixed, repeatable settings of customer controls, which allow consistent measurements to be made.
The SDM also initiates the blinking LED procedure and, if necessary, overrides the 5V protection.
The SDM places the set in the following pre-defined conditions:
•
Tuning frequency set to channel 3.
•
Volume level set to 25% (of the maximum volume level).
•
Other picture and sound settings set to 50% (mid-range).
The following functions are turned OFF while in SDM:
•
Timer
•
Sleep timer
The following functions are disabled during SDM (and enabled after leaving SDM):
•
Parental lock
•
Blue mute
•
Hospitality Mode
•
No-ident Timer (normally the set is automatically switched off when no video signal (IDENT) is received for
15 minutes).
All other controls operate normally.
Entering Service Default Mode
To enter the Service Default Mode, press the following key sequence on the remote control transmitter:
0-6-2-5-9-6-MENU

screen.
