■ Tone/DTCS squelch operation
The tone or DTCS squelch opens only when receiving a sig-
nal with the same pre-programmed subaudible tone or DTCS
code, respectively. You can wait for calls from group mem-
bers using the same tone or DTCS and not hear other sig-
nals.
q Set the operating frequency.
w Program the CTCSS tone frequency or DTCS code in set
mode.
• See p. 55 for programming details.
e Push [TONE•T-SCAN] several times until “T SQL” or
“DTCS” appears in the function display.
r When a signal with the matched tone is received, the
squelch opens and the signal can be heard.
• When the received signal includes an unmatched tone, the
squelch does not open. However, the S/RF indicator shows the
received signal strength.
• To open the squelch manually, push [MONI•DTMF].
t Transmit in the normal way (push [PTT] to transmit; re-
lease [PTT] to receive).
y To cancel the tone squelch, push [TONE•T-SCAN] several
times until “T SQL” or “DTCS” disappears.
z Set the operating frequency.
x Program the CTCSS tone frequency or DTCS
code in set mode.
• See p. 56 for programming details.
