There is power switch button on the front side.

There are 2 ranges "F1" and "F2" for measuring values indicated on the meter.

Time of measurement at "F1" range is 36 seconds.

Time of measurement at "F2" range is 12 seconds.

Red button "M" on the front panel is used for an input and an output in a mode of programming and change of value of fields.

OPERATION AND STORAGE CONDITIONS:

The dosimeter is intended for use at temperatures from 263 to 313 °K (0 to 40 °C, 0 to 104 °F), relative humidity up to 80%, normal atmospheric pressure (650-800 mm Hg).   Keep the radiation dosimeter clean and protect it from impact, dampness, and harsh environments.

After storing or transporting the radiation dosimeter in cold conditions, give it 2 to 3 hours to reach working temperature.  Remove the batteries if it is not going to be used.  Check that the battery contacts are clean before installing batteries.
