Polycom Vortex EF2211 User Manual

This command sets or queries the amount of time (in milliseconds) that the front panel buttons must
be idle before the screen saver starts.
This command is an integer command. See
Section 6.2 for more information on this type of
command. The minimum and maximum values for this command are 500 and 600000, respectively.
This command is saved to non-volatile memory only as part of a preset. The state of this command
will be restored after power-up only if a preset is saved and that preset is set to be the power-on
preset.

8.149. SSTEXT -- Set Text to be Displayed by Screen Saver
This command sets or queries the text messages displayed by the screen saver. The arguments of this
command are the screen number, the line number, and the text to be displayed. The screen number
must be between 0 and 3. It indicates which message screen we are trying to set or query. Each
message screen consists of two lines of text that can be up to 16 characters long. The second number
indicates which line of the message we are tring to set or query. The line number must be 0 or 1
corresponding to the first and second line, respectively. Finally, the text argument is the actual text
that will be displayed on the LCD. If the text is '?', then a query will be performed. If the text empty,
then the message will be cleared. If both message lines are cleared for a given screen, then that
screen will not be displayed by the screen saver. If all screens have been cleared, then the screen
saver will never start (although it is easier just to use the
SSEN command for this).
This command is saved to non-volatile memory only as part of a preset. The state of this command
will be restored after power-up only if a preset is saved and that preset is set to be the power-on
preset.
