PURPOSE
To adjust the idle time after which PPCH’s SCREEN SAVER activates.
PRINCIPLE
PPCH has a SCREEN SAVER function which causes the display to dim after a
front panel key is NOT pressed for a certain amount of time. The default screen
saver time activates the screen saver after 10 minutes. The screen saver activation
time can be adjusted by the user or screen saving can be completely eliminated.
Setting screen saver time to zero eliminates the SCREEN SAVER function so
that the display permanently remains at full brightness.

to dim the screen. Set the time to zero to eliminate the SCREEN SAVER function.

may be completely suppressed. Invalid key presses are indicated by a
descending two tone “blurp” which cannot be suppressed.
