A blinking red LED and a two-tone audible alarm
show that the programmed DER threshold level has
been exceeded.
Important! If the process of the new threshold level
programming is paused for more than 30 seconds (the
user presses no buttons of the dosimeter), the dosimeter
will automatically return to the mode of DER
measurement. All changes made in the submode of new
threshold level value programming will be canceled.
