5.3. Operating and Storage Temperatures

The operating and storage temperatures are listed in the following table.
Table 44: Operating and Storage Temperatures
Parameter
Operating Temperature Range
Extended Temperature Range
Storage Temperature Range
10 Within operation temperature range, the module is 3GPP compliant.
11 Within extended temperature range, the module remains the ability to establish and maintain a voice, SMS, data
transmission, emergency call*, etc. There is no unrecoverable malfunction. There are also no effects on radio spectrum
and no harm to radio network. Only one or more parameters like P
tolerances. When the temperature returns to the normal operation temperature levels, the module will meet 3GPP
specifications again.
