3.12 Flight Mode Control
The FLIGHTMODE pin can be used to control SIM7600SA-H to enter or exit the Flight mode. In
Flight mode, the RF circuit is closed to prevent interference with other equipments and minimize
current consumption. Bidirectional ESD protection component is suggested to add on
FLIGHTMODE pin, its reference circuit is shown in the following figure.
