The reference temperature measurement position is 50mm below the bottom of the base
unit.
For long-term storage, store spare parts in dark places and avoid hot or wet places.
For the product in long-term storage, the temperature and humidity shall be 0 to 40°C and
20 to 80%RH (no condensation) and the temperature change rate shall be 10°C/h or less.
Particularly store batteries and power supplies at the room temperature (25°C) or less as
their estimated usable periods are affected by high ambient temperatures.
