POCKET BEEP AND TONE SQUELCH
■ Tone scan
By monitoring a signal that is being operated with pocket
beep, tone or DTCS squelch function, you can determine the
tone frequency or DTCS code necessary to open a squelch.

matched, the squelch opens and the tone frequency is
temporarily programmed into the selected condition such
