disables thermal protection: turns on its RF transmission, and presents the
^THERM: 0 indication.
Notes:
During an emergency call, if thermal protection is enabled, the module will present an
indication but will not take thermal protection actions such as turning off its RF or shutting
down.
After thermal protection is enabled, users cannot make emergency calls.
Thermal protection is designed to protect the module from being damaged by
overtemperature. To work in high temperature environments, both the module and its
peripheral components must be able to resist the same temperature.
