2.3.4 Nonvolatile memory of the dosimeter
Nonvolatile memory of the dosimeter is arranged as two circular buffers. One
buffer automatically saves photon-ionizing radiation DE accumulation history. It
enables storing up to 2200 DE values. The other buffer, if the user decides so, stores
measurements results of alpha, beta and gamma radiation characteristics. This buffer
enables storing up to 1500 measurement results.
When the entire memory of the circular buffer is filled and new information continues
to be saved, the oldest information is deleted. In order to prevent information loss, it is
necessary to transfer it from the nonvolatile memory to the PC in time.

dosimeter except for the "Measurements results viewing stored in the nonvolatile
memory" mode and "Measurement result saving in the nonvolatile memory"
submode, if the circular buffer intended for DE accumulation history autosaving can
provide for less than 10 DE records, or if information has already been lost.

delayed transfer from the nonvolatile memory of the dosimeter to the PC.
2.3.5 Operating submodes and modes of the control unit
2.3.5.1 The control unit operates in the following modes:
- display of measurement results obtained from the probes or detectors;
- display of accumulated DE and DE accumulation time;
- navigation receiver control;
- display of current time and date;
- measurements results viewing stored in the nonvolatile memory.
2.3.5.2 After switching on, the control unit always enters the mode of
measurement results display obtained from the probes or detectors.
By shortly pressing MODE, you change the operating modes in the following
sequence:
- measurement results display obtained from the probes or detectors;
- display of accumulated DE and DE accumulation time;
- navigation receiver control;
- display of current time and date;
- viewing measurements results stored in the nonvolatile memory.
