This feature alternately writes Time Up Count values from the CPU to the RAS feature’s
special programmable timer and then periodically clears them, which provides a means
of monitoring CPU performance. If the clearing of this count value is stopped, the timer
will overflow and an alarm will be detected. The System Monitor utility can be used to
enable or disable this feature, as well as designate what type of processing is performed.
Touch Panel Alarm
This feature detects a Touch Panel alarm. When this alarm occurs, the PL unit's front
panel LED indicator will blink.
Backlight Burnout Detection
This feature allows you to detect when the PL unit's backlight burns out.
When this feature is enabled and a backlight burnout occurs, touch operation will be
disabled and PL unit's front panel LED indicator will blink red and orange. The factory
setting is "Enabled" and is recommended to prevent accidental touch panel operation.
This setting is controlled via the MS-DOS utility BLSET.EXE. For details,
