If the nonvolatile memory has no saved measurement results, a short press
of the MODE button switches the dosimeter from the mode of data
communications control with the PC directly to the mode of photon-ionizing
radiation DER measurement.
A short or a long press of the THRESHOLD button in any operating
mode of the dosimeter changes the submodes of this operating mode. A
detailed description of each operating mode of the dosimeter with its
submodes is given below.
2.3.3.4 Alarm type change
The dosimeter provides the option to choose between three alarm
types: audio, vibration and vibration-audio. Irrespective of the operating
mode of the dosimeter a short press of the two buttons at a time (MODE
and THRESHOLD) changes the alarm type and activates it for a short time.
The alarm type is displayed on the LCD with "AUD" and/or "VIBR"
symbols (6) (Figure 3).
