When the CTCSS or DTCS squelch function is ON,
the tone encoder is activated while transmitting.
6. Operate the transceiver in a normal way; push
[PTT] to transmit, release [PTT] to receive.
7. When a signal with matching tones or codes is
received, the squelch opens and audio is heard.

If the signal includes an unmatching tones,
the squelch does not open. However, the icon
shows the strength of the received signal.
8. To cancel the tone or DTCS squelch, push
[FUNC], and then push [TONE] several times,
until the tone icon disappears.
CTCSS burst:
While using the tone squelch, noise may be heard
just when the received signal disappears.
To eliminate the noise, the transceiver has the
CTCSS Burst function. See page 8-7 for details.
