16.3 Automatically Transmitting and Receiving in Emergency Mode
Emergency Mic Sense
Emergency Mic Sense is the function used to adjust the microphone input sensitivity in Emergency Mode.
In Emergency Mic Sense, the microphone sensitivity can be configured within the following range.
6dB, 4dB (High), 2dB, 0dB (Normal), -2dB, -4dB, -6dB, -8dB, -10dB (Low), -12dB, -14dB, -16dB, -18dB, -20dB
The appropriate level of microphone sensitivity for normal operation is 0 dB. Based on this level, the parameter of the
microphone sensitivity can be configured.
Note
If a level lower than "0 dB" is configured for Emergency Mic Sense, the amplitude limit level is also lowered simultaneously; so
Modulation Limiting (minimum) in Analog FM will be lowered.

Background Transmission
Background Transmission is the function to multiplex a Background Tone on the transmitted audio when the transceiver
transmits in Emergency Mode. Background Tone is multiplexed every 1 sec while the transceiver is transmitting audio
data.
The audio signal is not muted since the Background Tone is transmitted with lower deviation than normal. The receiving
transceiver can easily recognize that the transmitting transceiver is in Emergency Mode if the tone is multiplexed while
initiating a voice call.
