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