Introduction
Used in conjunction with the Scroll button, the display screen
allows you to view different pages of information. See
Display Screens on page
9 for a detailed description of the
information available from this screen.
After a few seconds of inactivity (i.e. Scroll button idle),
screen luminosity turns from high to low level.
Scroll button
Press this button shortly to scroll through the different pages
of information viewed on the screen.
If an alarm is reported on the display screen, a short press on
the Scroll button will acknowledge the alarm. The Scroll
button will recover its display scrolling function only after all
the alarms have been acknowledged this way.
Another function of the Scroll button is to re-activate the
screen backlight after the latter has automatically been
turned off. The Scroll button is also used in the firmware
update procedure.
Log Button
Press this button briefly to start recording raw data on the
selected storage medium.
Another short press on this button will immediately stop raw
data recording.
Buzzer
The internal buzzer will sound an alarm whenever a warning
message is reported on the screen. The buzzer will beep until
you acknowledge the warning message by pressing the Scroll
button. The buzzer can be deactivated permanently using the
$PASHS,BEEP command. See BEEP: Beeper Setup on
page 159.
