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 and DCS setting are also active during scanning. If scanning is performed with
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 M for 1 second, and then changing the Set mode option allows you to use
this function more conveniently.
[4 SIGNALING]  [3 DCS INVERSION]: Allows you to receive the DCS code of the inverted phase.
[4 SIGNALING]  [10 SQL EXPANTION]: Allows you to specify different squelch types for
transmission and reception respectively.
