
PURPOSE
To adjust the time of inactivity after which PG9000’s SCREEN SAVER function
activates or to turn off the screen saver function.

PRINCIPLE
PG9000 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 time
activates the screen saver after 10 minutes. The time can be adjusted by the
user or screen saving can be disabled.

OPERATION
To access the SCREEN SAVER function, press [SPECIAL] and select
<4prefs> , <1ScrSav> . Edit the time, in minutes, after which the screen saver will
activate to dim the screen. Set zero to disable the SCREEN SAVER function. It is
recommended to enable the screen saver to help extend the life of the PG
Terminal display.
Note
Setting the screen saver time to zero disables the screen saver
function so that the display remains permanently at full brightness.
3.12.4.2 <4prefs>, <2sound>

PURPOSE
To adjust the sounds associated with key pad presses, and to turn the piston
position sounds ON and OFF.

PRINCIPLE
PG9000 provides audible feedback of valid and invalid key presses and of when
the piston leaves the high or low stop position (see Section 3.5). An audible
“chirp” sound is emitted when the piston begins to move away from either the low
or high stop. This feature is useful to indicate to the operator when the attention
should be refocused from the pressure generation device to the piston position
indication.
Key press sounds can be adjusted in frequency or turned OFF completely.
Piston position sounds may be turned ON and OFF.
