The dosimeter can be switched off at any moment by pressing the ON / OFF button. The
button must be depressed for one or two seconds until the ON light switches off. This is so
that if the button is pressed accidentally the device will not be switched off.
3 audio beeps are emitted, indicating that the device is switching off.
If switched off in mid measurement cycle, the cycle will pick up where it left off when the
dosimeter is switched back on. This downtime will not be recorded in the total time of the
measurement recording cycle.
