SERVICE ALIGNMENT MODE (SAM)
1. The Service Alignment Mode (SAM) is used to set the option codes and bytes of the set, and display the
error codes (the Power LED begins blinking procedure for error code display, if errors are detected). SAM
also overrides software protections.
2. To enter the Service Alignment Mode, press the following key sequence on the remote control transmitter:
0-6-2-5-9-6-Status
Do not allow the display to time out between entries while keying the sequence.
SAM can also be entered by pressing the Channel Down and Volume Down keys on the local keyboard
simultaneously while in SDM mode.
When Service Alignment Mode is entered, the text "SAM" will be displayed in the upper right corner of the
screen.
3. When Service Alignment Mode is entered, the Power LED will begin blinking to display any detected error
codes, and service unfriendly modes are disabled. All customer controls are set to predetermined values.
4. When the unit is operating in Service Alignment Mode, all normal on-screen displays are suppressed and
replaced by a special service display. The first screen seen upon entering SAM is the "top level SAM
menu." The service technician must return to the top level SAM menu before exiting with a power-off
command.
A sample top level SAM menu display is shown below.
