3.9.1. W_DISABLE1# Signal
EM06 provides a W_DISABLE1# signal to disable or enable airplane mode through hardware operation.
The W_DISABLE1# pin is pulled up by default. Driving it to low level will let the module enter into airplane
mode.
In airplane mode, the RF function will be disabled. The RF function can also be enabled or disabled
through software AT commands. The following table shows the RF function status of the module.

3.9.2. WWAN_LED# Signal
The WWAN_LED# signal is used to indicate the RF status of the module, and its typical current
consumption is up to 40mA.
In order to reduce the current consumption of the LED, a resistor must be placed in series with the LED,
as illustrated in the figure below. The LED is ON when the WWAN_LED# signal is at a low voltage level.
