interferance with other stations that may be using the same
channel.
While the selected channel is in use, pressing PTT
causes the RADIO to sound a warning tone, and transmis-
sion is inhibited. To stop the warning tone, release PTT.
If BCL Override has been enabled, pressing PTT within
500msec again will cancel BCL, and transmission is en-
abled.

26. 2Tone Signalling

2Tone signalling opens the squelch only when the RA-
DIO receives a proper 2Tone code that is the same as the
pre-programmed 2Tone for the channel. When the RADIO
receives a 2Tone code, the CALL icon flashes.
If Transpond has been programmed, the RADIO will re-
turn an acknowledgment signal automatically after receiving
the 2Tone code.
If Call Alert has been programmed, an Alert Tone sounds
after receiving a 2Tone code. You can configure "Normal"
(an alert tone beeps once) or "Continuous" (an alert tone
beeps every 5 seconds) for the Call Alert. Unmute condition
is canceled and the CALL icon goes off when ; (1) pressing
the [MON] Key, (2) hanging the microphone on its hook, (3)
muting continues for 10 seconds. (If "Auto Reset" has been
programmed)

27. DTMF Signalling

DTMF Signalling opens the squelch only when the RA-
DIO receives a proper DTMF code that is the same as the
pre-programmed "Primary Code (Individual ; 1~7digits)" or
"Secondary Code (Group ; 1~7digits)". When the RADIO re-
ceives a correct code, the CALL icon flashes.
If Transpond has been programmed, the RADIO will re-
turn an acknowledgment signal automatically after receiving
the DTMF code.
If Call Alert has been programmed, an Alert Tone sounds
after receiving a DTMF code. You can configure "Normal"
(an alert tone beeps once) or "Continuous" (an alert tone
beeps every 5 seconds) for the Call Alert. Unmute condition
is canceled and the CALL icon goes off when ; (1) pressing
the [MON] Key, (2) hanging the microphone on its hook, (3)
muting continues for 10 seconds (If "Auto Reset" has been
programmed), and (4) receiving reset code. (Primary code +
"#" or secondary code + "#")

28. Time Out Timer

(Possible to configure to each group)
The Time Out Timer function interrupts continuous trans-
mission after a specified time elapses.
Holding down PTT for longer than the programmed time
causes the RADIO to stop transmitting and sound a warning
tone. To stop the warning tone, release PTT.
