Note: For battery models, if the storage temperature and humidity ranges for the
batteries are more narrow than the ranges for the MCF, the ranges for the
battery have priority.
Example: If batteries with a storage temperature range of -10 to +50 °C
are used, the storage temperature range for the MCF becomes
-10 to +50 °C.
If batteries with a storage temperature range of -15 to +50 °C
are used, the storage temperature range for the MCF becomes
-10 to +50 °C
