The transceiver reverts to the receive state.
Note:
◆ Speak into the microphone in your normal voice. If the microphone
is too close to your mouth or your voice is too loud, signal distortion
may occur and cause the received audio in receiving transceiver to
be unclear.
◆ Refer to "Speech Processor" for the details of the speech
processor. {page 9-6}
◆ If you use a microphone with a built-in AF amplifier, you must
carefully adjust the output level of the microphone not to be too
high.
◆ For use in FM mode, configure the microphone gain in Advanced
Menu 13, "Microphone Gain (FM Mode)".
