Important! Only Li-Ion Batteries of 26650 size, rated voltage 3.7 V, with the
integrated board of protection against overcharging, prevention of discharge and
short-circuit are allowed.
Note. The clock of the dosimeter is powered from the storage battery. The
dosimeter's clock has no additional sources of power supply. Therefore, the first time
after the battery is inserted into the MKS-UM battery compartment and it is switched
on, it enters the submode of time and date correction to set their accurate values
(2.3.6.9.5 of this OM).
