Background Tone Transmission is the function to multiplex a Background Tone (1 beep) on the transmitted
audio when the transceiver transmits in Emergency Mode. Background Tone (1 beep) is multiplexed every
second 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.
-
A Background Tone is not emitted from the speaker of the transmitting transceiver.
