Selecting the squelch level
The squelch level determines the sensitivity of the audio signals to be transmitted through
the speaker. There are 4 levels for selection. With setting 1, even weak signals are transmit-
ted. With setting 4, only strong signals are transmitted. Set the required setting to prevent
unwanted background noises being transmitted through the speaker.

detects a voice or a sound.
When you start to speak, there is a slight delay before the walkie−talkie
starts to transmit.
