4. Alarm messages
4.1 Dose and dose rate alarm
When an acvated alarm threshold is exceed-
ed, the display is blinking.
In case of an exceeded dose alarm threshold,
the display switches to the dose indicaon
and in case of an exceeded dose rate alarm
threshold to the dose rate indicaon. If both,
the dose and the dose rate alarm threshold are
exceeded, the „Twin“-indicaon is displayed.
In case of a dose rate alarm short constant
acousc warning signals will be triggered. If the
acousc alarm has been acvated in the menu,
the warning signal sounds every second.
Such an alarm can be acknowledged by means
of the -key. Thus, the acousc alarm is swit-
ched o and the menu returns to the selec-
ted standard display. But, the triggered alarm
threshold is sll blinking.
The acousc alarm will be re-triggered as soon
as the measured value falls below an already
acknowledged dose rate alarm threshold and is
then exceeded again.
