6.3. Operating and Storage Temperatures
The operating and storage temperatures are listed in the following table.
Table 33: Operating and Storage Temperatures
1.
1)
Within operating temperature range, the module is 3GPP compliant.
2.
2)
Within extended temperature range, the module remains the ability to establish and maintain a
voice, SMS, data transmission, 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
out
might reduce
in their value and exceed the specified tolerances. When the temperature returns to the normal
