6.4 Time-Control
The radio will restart the scan after pausing for some time while receiv-
ing signal .The pausing time can be preset from 0.5 to 5 seconds.
6.5 Carrier Wave Control
The radio will pause the scan after receiving signals and will restart
scan after the signal disappears.
6.6 Calling Back
The working channel of the radio will return to the following channels
automatically by pressing PTT during the scan. The dealer can select
one among the following four ways.
1) Selected channel:
When pressing PTT during the scan, the radio will always transmit
from the first channel of the scanning list.
2) Selected channel or currently working channel:
If pressing PTT during scanning, the radio will transmit from the first
channel in the scanning list. If pressing PTT during the scan paus-
ing, the radio will transmit from current channel.
3) Prior channel:
The radio will always send signals from the prior channel in the scan
list when pressing PTT.
4) Prior channel or currently working channel:
When the radio is scanning, it will send signals from the prior chan-
nel in the scanning list by pressing PTT. During the pause of scan,
the radio will transmit from current channel by pressing PTT.
7 OTHER OPERATIONS
7.1 Time-Out -Timer (TOT)
Caused by continuous transmission. If you transmit con-tinuously over
the preset time, the unit will stop the transmitting and return to standby
mode.
Time Out Timer
The purpose of the Time -out- timer is to prevent any single person
from using a channel to transmit for an extended period of the time. If
you continuously transmit longer than the time limit preset by the dis-
tributor, the radio will stop transmitting and a tone will be heard. To stop
the tone, release the PTT button. You can press the PTT again to
resume transmitting.
TOT Pre-Alert
The TOT Pre-Alert function notifies that the programmed time is
expired. This should be set less than TOT value. Rang: Off /1 to 10s
(1s steps) Default: Off
TOT Rekey Time
TOT Rekey-Time sets the penalty time in which the radio can not
be rekeyed for transmitting after the Time-Out-Timer setting is
exceeded.
Range: Off /1 to 60s (1s steps)Default: Off
TOT Reset Time
TOT Reset Time sets the minimum wait time allowed between trans-
missions that will reset the Time-Out -Timer. When TOT Reset Time is
set , it causes the TOT continue even after PTT is released unless the
TOT Reset Timer has expired.
Range: Off /1 to 15s (1s steps)Default: Off
7.2 Busy Channel Lockout (BCL)
The function of busy channel lockout (BLC) is turned ON or OFF by the
local dealer, also can be set by user in self-programming mode.
When the BLC function is on, it can prevent other transceivers from
interfering with your transceiver by using the same frequency. When
press the PTT key, a beep alarm will ring until the PTT key is released
and it will go back to stand-by mode, if the channel is busy.
7.3 Monitor
When there is no signal, the squelch circuit will mute the speaker auto-
matically and you will not hear the background noise. To inactivate the
squelch circuit, press the
MON
key, which is very useful when you
adjust volume or want to receive weak signals. When pressing the
MON
key, the status indicator lights green and the radio is in the state
of monitoring.
7.4 Clear Tail Tone
When using the channel set with CTCSS/DCS, the after sound in tal-
king ending can be eliminated.
7.5 CTCSS/DCS
Your dealer can program CTCSS/DCS signaling on the radio channels.
CTCSS/DCS allows you to ignore (not hear) calls from other parties
who are using the same channel.
The channel preset with CTCSS/DCS signaling can activate the
squelch only when it receives the correct CTCSS/DCS signaling. Like-
wise, only the radios whose CTCSS/DCS is the same as yours can
hear the signals you transmit.
Using a CTCSS/DCS channel does not mean your calls are private. If
other parties' CTCSS/DCS is identical with yours, they can hear your
calls.
7.6 DTMF
The dealer can activate or inactivate this function by programming.
1) Receiving Signals
Only when the radio receives the programmed DTMF code (3~10
digits), the squelch will be activated. Usually every channel has uni-
que code. Calls from the radios that are not programmed with mat-
ching codes will not be heard.
The dealer can also program group codes on the radio.
