ECOTEST MKS-05 TERRA Operating Manual page 80

Proceeding to the submode of measurement result saving should be
confirmed by a short press of the MODE button. Press shortly the
THRESHOLD button to cancel the action. If the buttons are not pressed for
30 s, the dosimeter automatically returns to the mode of surface beta-
particles flux density measurement.
If the "FULL" symbols are displayed on the LCD of the dosimeter
(Figure 19) instead of the "Arch" symbols, there is no free space in the
nonvolatile memory of the dosimeter, and, correspondingly, the next
measurement results cannot be saved. To clear the space in the nonvolatile
memory, delete its saved measurement results. Measurement results can be
cleared during data communications with the PC (2.3.3.12 of the OM) or in
the viewing mode (2.3.3.13 of the OM).
