Normal shutdown after sending the AT^SMSO command. Only a voltage regulator is active
for powering the RTC. Software is not active. Interfaces are not accessible. Operating volt-
age (connected to BATT+) remains applied.
Airplane

Airplane mode shuts down the radio part of the module, causes the module to log off from
the CDMA network and disables all AT commands whose execution requires a radio con-
nection.
Airplane mode can be controlled by AT command (see [1]).
