Note on the dose display:
The natural background radiation in Germany varies between 0.5 mSv and 2 mSv per year.
Thus, doses between 1 and 2 µSv per working day correspond to the background due to
natural environmental radiation.
Audible warnings:
The EPD delivers an audible warning (beep) on two occasions:
•
as an acknowledgment signal when the operating button is pressed
•
as a warning signal
Confirm warning signals: (hold for 2 seconds)
The EPD responds to certain events by delivering different warning signals, which can be
confirmed and muted with a long keystroke. During the warning, the reason for the warning
signals is indicated in the display screen and the LED signal (on the right side of the display
screen) is active. Both display screen and LED are blinking every second.
