4.1.7 Monitor
When no signals are being received, the radio squelch circuit mutes
the speaker.
Press the MONI key to cut off the squelch control circuit, and you
will hear noise from speaker (no mater whether there are signals).
Such operation is very useful when you want to adjust voice volume
or receive weak signals (to avoid voice intermittence when in weak
signals).
When you press the MONI key, the green indicator lights, and the
radio is in the state of monitoring.

5-Tone Signaling
The dealer can activate or inactivate this function by programming.
5-Tone Signaling has 17 coding formats: CCIR1, CCIR2, PCCIR,
ZVEI1, ZVEI2, ZVEI3, PZVEI, DZVEI, PDZVEI, EEA, EURO
SIGNAL,NATEL, EIA, CCITT, MODAT, USER DEFINED1, and
USER DEFINED2. The last two are customized models.
1) 5-Tone Decoding
When receiving proper 5-tone signal, squelch will be activated
according to the
“
SP unmute
”
set by the user, and the radio can
receive the call and orange LED flashes.
The dealer can program the response way after decoding
succeeds.
2) 5-Tone Encoding:
If the PTT ID on the channel you select has been set with 5-Tone, 5-
Tone signal will be transmitted when making a call.
Or transmit 5-Tone signal by pressing the PTT button and CALL1 or
CALL2 button, which can be set by the dealer.
4.1.9
、
2-Tone Signaling
The dealer can activate or inactivate this function by programming.
1) 2-Tone Decoding
When receiving proper 2-Tone signal, squelch will be activated
according to the
“
SP unmute
”
set by the user, and the radio can
receive the call and orange LED flashes.
The dealer can program the response way after decoding
succeeds.
2) 2-Tone Encoding:
If the PTT ID on the channel you select has been set with 2-Tone, 2-
Tone signal will be transmitted when making a call.
Or transmit 2-Tone signal by pressing the PTT button and CALL1 or
CALL2 button, which can be set by the dealer.
4.1.10
、
PC Programmable
You can program the radio functions and adjust some parameters
by PC programming software KSP5200.
4.1.11
、
Busy Channel Lockout
If
“
busy channel lockout
”
has been activated, transmitting signals
is prohibited on the busy channel. If you press the PTT to transmit
on the busy channel, the speaker will sound busy channel lockout
tone, and you cannot transmit signals.
The dealer can set one of the following BCL types:
1) OFF: BCL is inactive and you can transmit on the busy channel.
2) Carrier wave: If carrier wave is detected, the radio is unable to
transmit.
3) CTCSS/DCS: The radio is allowed to transmit when the
CTCSS/DCS signalings are identical.
4) Selective signaling: The radio is allowed to transmit when the
selective signalings (2-Tone or 5-Tone) are identical.
4.1.12 Squelch Level Selection
The purpose of the squelch is to mute the speaker noise when no
signals are received or the signals are weak. When the squelch is
activated, you can hear noise from the speaker; when the squelch
is inactivated, you will not hear noise form the speaker. Selecting
the squelch level is to select which the signal strength level is
strong enough to enable the squelch or weak enough to disable the
squelch. Over high squelch level will make the radio unable to
receive signals efficiently when signals are weak; over low squelch
level will make the radio communication affected by noise or other
irrelevant signals. The squelch level has 0-9 options.
4.1.13 Beep Tone
This option controls power on tone, channel busy tone and TOT
tone.
4.2 Parameter Setting (PC Mode)
The radio parameters have been programmed in the factory. The
user can program the radio parameters such as working frequency,
channels, CTCSS/DCS, auto scanning. We designed a user friendly
and convenient Chinese/English programming software KSP20 for
users to set parameters on the radio. The programming steps are
as follows:
A. Install the programming software KSP 5200 on the computer.
b. Connect the radio to the computer serial port with the specified
programming line (KSPL02). See Figure 4.1
Figure 4.1
C. Turn on the computer power.
D. Turn on the radio power.
E. Click the KSP5200 program to run the programming software.
F. Click the
“
Program
”
in the KSP5200 pull-down menu, and click
“
Read from Radio
”
to read the radio parameters into the
computer; click
“
Write to Radio
”
to transfer the PC programming
parameters into the radio.
G. You can program the following parameters with the KSP5200
software.
1)
The RX and TX frequency of each channel.
2)
The receiving and transmitting signaling of each channel.
3)
Busy channel lockout option.
4)
TOT
5)
Squelch level option.
6)
5-Tone
7)
2-Tone
8)
Power saving option.
9)
Beep tone option.
10)
Monitor mode option.
11)
Scan mode option.
12)
Scan the revert channel option.
13)
Scan the priority channel option.
