OPERATION
CTess ENCODE AND TONE SQUELCH OPERATION
Many repeaters require a CTCSS Encode or 1750 Hz Burst Tone in order for the repeater
to be activated. The CTCSS Tone Squelch feature (CTCSS "Decoder"), moreover, allows
you to monitor silently for calls on busy channels, with your receiver's Squelch only open-
ing up when a signal bearing the matching CTCSS tone appears on your frequency. The
Tone Squelch feature requires the installation of the optional FTS-27 module (see page
107)
I. Set the CTCSS Tone frequency via
MENU
#12 (TONE FREQ).
2. Press the [FUNC] key, as needed, to recall Operating Function Row 3 [TON, DCS,
ART], then press the [A](TON) key once to activate the Tone Encoder (the "ENC" icon
will appear on the display). When you transmit, the Subaudible tone selected via MENU
#12 will be superimposed on your signal, allowing repeater access.
3. For CTCSS Encode/Decode operation, press the [A](TON) key once more; the "TSQ"
indicator will replace the "ENC" indication on the display. The receiver will become
silent, unless a station bearing a CTCSS tone matching that of your transceiver appears
on frequency. When this happens, the Squelch will open and normal reception will
commence.
4. Press the [A](TON) key once mode to cancel CTCSS Tone Squelch operation (the
"ENC" and "TSQ" icons will disappear).
