Invalid Channel Indication
Squelch
The squelch level decides how strong the signal is to
unmute the speaker. The lower the squelch level is, the
stronger the background noise is to unmute the speaker.
The larger the talk range is, the weaker the Rx anti-
interference ability is. Setting range is 0~9, it causes
the squelch to open by selecting “0”. The higher the
squelch level is, the harder to open the squelch.
