I Tone/Dtcs Squelch; I Digital Code/Digital Call Sign Squelch - Icom IC-91A Instruction Manual

I Tone/DTCS squelch

q Set the desired operating frequency, CTCSS tone and
DTCS code.
w Push and hold [7/DSQ/TONE] for 1 sec. several times to
activate the tone or DTCS squelch. (TONE, TSQL or
DTCS)
• Subaudible tone encoder "TONE," tone squelch "TSQL," pocket
beep "TSQLS," DTCS squelch "DTCS," DTCS beep
"DTCSS" and no tone operation are activated in order.
• Rotating [DIAL] while pushing [7/DSQ/TONE] also selects the
tone functions.
e Operate the transceiver in the normal way.
r When the received signal includes a matching tone/code,
the squelch opens and the signal can be heard.
• When the received signal's tone/code does not match,
tone/DTCS squelch does not open, however, the S-indicator
shows signal strength.
• To open the squelch manually, push and hold [SQL].
