selected CTCSS tone is received. To answer the call,
press and hold [PTT], then speak into the microphone.
Note:
◆
You cannot use the CTCSS and Tone/ DCS functions
simultaneously. Switching the CTCSS function ON after having
activated the Tone/ DCS functions deactivates the Tone/ DCS
functions.
◆
If you select a high CTCSS frequency, receiving audio or noise
that contains the same frequency portions may cause CTCSS to
function incorrectly. To prevent noise from causing this problem,
select an appropriate squelch level {page 18}.
◆
While transmitting the 1750 Hz tone by pressing [CALL]
{page 35}, the transceiver does not transmit the CTCSS tone.
