The LED flashes orange.
The dealer can program that squelch turns off after a certain time
and LED turns dim.
If DTMF auto reply has been programmed, the calling radio will
receive confirming signals.
If DTMF signal reminder has been programmed, it rings when
receiving the proper code.
2) Transmitting Signals
You can transmit the preset DTMF PTT ID code by pressing the PTT
button. Or you can also transmit the DTMF code by pressing the
function button CALLA or CALLB if the DTMF signaling has been
programmed on the channel.
7.7 2-Tone Signaling
The dealer can activate or inactivate this function by programming.
1) Receiving Signals:
When receiving the proper 2-Tone signaling, the squelch will be acti-
vated, and you can receive the call. The LED flashes orange.
To manually mute the speaker, press the monitor key or the side but-
ton set as instantaneous monitor.
The dealer can program that the squelch turns half active certain
time after the signal disappears.
If auto reply has been set, the calling radio will receive confirming
signals.
If signal reminder has been set, the warning tone sounds when the
radio receives the proper 2-Tone code.
2) Transmitting Signals:
If the 2-Tone signaling has been set on the channel, you can trans-
mit the 2-Tone signals by pressing the side button CALLA or CALLB,
which can be set by the dealer.
After transmitting the signal, indicator flashes orange and you can
talk to other radios until the effective time expires and the indicator
turns dim.
7.8 5-Tone Signaling
The dealer can activate or inactivate this function by programming.
5-Tone Signaling has 7 coding formats: CCIR, ZVEI1, ZVEI2, DZVEI,
EEA, PZVEI, and EIA.
1) Receiving Signals:
When receiving the proper 5-tone signal, the squelch will be activated,
and you can receive the call. The LED lights orange.
The dealer can program that the squelch turns half active certain
time after the signal disappears.
If auto reply has been set, the calling radio will receive confirming
signals.
If signal reminder has been set, the warning tone sounds when the
radio receives the proper 5-Tone signals.
2) Transmitting Signals:
If the PTT ID on the channel you select has been set with 5-Tone,
the 5-Tone signal will be transmitted when making a call.
Or transmit the 5-Tone signal by pressing the PTT button and
CALL1 or CALL2 button, which can be set by the dealer.
7.9 Talk Around
When the radio is out of the repeater service range, or the repeater is
cut off due to power failure or any other reasons, you can communicate
with other radios by the Talk Around function. However, it might be
unable to communicate with others if it is too far away or it is hindered
by geographical obstruction.
You can set the A or B keys to start or end the Talk Around.
When in the Talk Around communication, the radio receiving and trans-
mitting frequencies are the receiving frequencies set in the original pro-
gramming (communication in the same frequency). The CTCSS/DCS
encoding and decoding will be resumed to the original decoding audio
if they have been set differently.
7.10 Reverse Frequency
The dealer can set the reverse frequency function instead of the Talk
Around on your radio.
When the reverse frequency is active, the transmitting and receiving
frequencies are exchanged with each other. CTCSS/DCS encoding
and decoding are also exchanged.
You can set the A and B keys to start or end the reverse frequency com-
munication.
7.11 Auto Channel Selection (ACS)
If there is more than one local repeater, the user can activate the ACS
function to scan these repeaters separately to find the desired repeater.
The user can select the ACS function by setting the A and B keys.
When the radio is in the ACS receiving state, press the PTT button to
reply on the channel that receives the strongest signals. You cannot
reply if it is in transmitting state.
When the user exits the ACS state, the radio will stay on the channel
that receives the strongest signals.
