Carrier Squelch mode; the scanner stops on any transmission regardless of whether a subaudible tone is present.
2:TONE SQ
The scanner stops on transmissions that include a matching subaudible tone or have no tone at all. When you select this option, you also need to set the appropriate tone in either the channel memory or for the search range.
