Tone/DTCS squelch operation | Icom IC-208H guide

■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.

qSet the operating frequency.

wProgram the CTCSS tone frequency or DTCS code in set mode.

• See p. 52 for programming details.

ePush [TONE•T-SCAN] several times until “T SQL” or “DTCS” appears in the function display.

rWhen 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].

tOperate the transceiver in the normal way (push [PTT] to transmit; release [PTT] to receive).

yTo cancel the tone squelch, push [TONE•T-SCAN] several times until “T SQL” or “DTCS” disappears.

zSet the operating frequency.

TSQL x Program the CTCSS tone frequency or DTCS code in set mode.

• See p. 52 for programming details.

DTCS c Push [FUNC] then [SIMP 9(TSQL)] or [HIGH 4(DTCS)] to turn the tone squelch or DTCS squelch ON.

vWhen a signal with the matched tone is re- ceived, 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 1(BANK)].

b Operate the transceiver in the normal way (push	10
[PTT] to transmit; release [PTT] to receive).

nTo cancel the tone squelch, push [FUNC] then [ENT C(T-OFF)].

• “T SQL” or “DTCS” disappears.
