Selective Calling Operations
• To communicate only with selected stations, use either the Tone Squelch or the DCS
function.
The Tone Squelch function unmutes the squelch only when a signal added with one
of the matching 39 CTCSS tone frequencies is received.
• The DCS function unmutes the squelch only when a signal added with one of
matching 104 digital codes is received.
• It isn't possible to use the Tone Squelch and DCS functions at the same time.
6.1.1 Setting the Tone Squelch
1. Press the FUNC key, and while
is displayed on the LCD, press the
key to display the current TSQ settings. Each time the
key is pressed,
the display shows:
• When only
is displayed, the unit encodes the CTSS tone.
• When
is displayed, the unit encodes and decodes the CTCSS tone.
2. Rotate the dial while the tone frequency is displayed to select one of the 39 CTCSS
tones shown below. The tone can be set for encode/decode separately (refer to
page 36 for details).
