 PURPOSE
To adjust the idle time after which RPM4’s SCREEN SAVER activates.
 PRINCIPLE
RPM4-AD 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 is for the
screen saver to activate after 10 idle 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.

OPERATION

 PRINCIPLE
RPM4-AD provides audible feedback by a brief “beep” when a valid key press is

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

<2sound> .
Select between <2lo> , <3mid> or <4hi> to adjust the valid key press tone frequency.

The sound function only affects the valid key press tone. The invalid key
press tone and other RPM4-AD sounds cannot be adjusted or suppressed.
