Communicating with a Specific Remote Station
Communicating with a Specific Remote Station
Using the Tone Squelch Function
The tone squelch opens the squelch only when a signal containing the specified
frequency tone is received. Use of the digital code squelch (DCS) opens the squelch
only when a signal containing the specified DCS code is received. The tone squelch
function mutes monitoring the communications between other stations, even when
listening for a call by a specific station for a long time.

Tips

the tone squelch or the DCS function turned on, it stops only when a signal containing a tone of the
specified frequency or a signal containing the specified DCS code is received.
• Pressing the Monitor switch allows you to hear signals that do not contain a tone or DCS code, and
signals with different tones or DCS code.
• Pressing and holding

this function more conveniently.
