2.3.6.8.3.2 If you keep holding THRESHOLD for more than 4 s, the value of
the alarm threshold level is returned to zero, and its low-order digit starts blinking
(Figure 2.28). Then release THRESHOLD.
(submode of the alarm threshold level programming)
Programming of the alarm threshold level relative to the accumulated DE value
is done in a similar way to programming of the alarm threshold level in the event of
photon-ionizing radiation DER measurement (2.3.6.5.3.2 of this OM).
Important! Programming a zero value of the threshold level turns off the alarm
of this threshold.

Important
for more than 20 seconds (the user will not click any buttons), the control unit
automatically returns to the mode of accumulated DE and DE accumulation time
display. All changes that have been made in this programming submode will be
canceled.
2.3.6.8.4 Submode of the control unit of the dosimeter "Clearing the values
of DE, DE accumulation time and DE accumulation history"
2.3.6.8.4.1 Press UNITS/CLEAR and hold it down (circa 4 s) until "CLr"
symbols (1) appear on the LCD to proceed to the submode of DE, DE accumulation
time and DE accumulation history values clearing (Figure 2.29). Then release
UNITS/CLEAR.
In this submode you should finally confirm or cancel clearing with the help of
the symbols (2). The symbol status (2) changes by shortly pressing
RAYS/RESTART. If "-On-" is displayed, clearing is confirmed, if "-OFF" is
displayed – it is cancelled. Press ON/SAVE to exit this submode. The control unit
returns to the mode of accumulated DE and DE accumulation time display.
