5.4. Reset the Module
The reset option is only used in case of emergency. For example, the software does not respond for more
than 5s due to some serious problems.
Press the RESET button S303 for more than 150ms then release it to reset the module. However, this
operation may cause the loss of information stored in the memory as the reset module has been
initialized.
5.5. Turn off the Module
There are two ways to turn off the module.
One way is to execute
AT+QPOWD
command. This is the best and the safest way since the module will
log off from the network and save data before shutdown. When turning off module with AT command,
please keep PWRKEY at high level after the execution of power-off command, otherwise the module will
be turned on again after successful turn-off. For more details about the AT command, please refer to
document [4]

The other way to turn off the module is to press down S302 (PWRKEY) for at least 0.6s.
