NOTES
1)
1. Within operation 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, emergency call* (emergency call is not supported on ThreadX
modules), etc. There is no unrecoverable malfunction. There are also no effects on radio spectrum
