You can enter User Mode (conventional communication mode)
by turning the radio power ON. Under this mode, users can use
the defined functions of the mobile radio.
5.2 Data Programming Mode
The radio has been set before leaving the factory. However,
due to different requirements of users, the radio’s operating
frequency, channels, CTCSS/DCS, scan, and other functional
parameters should be reprogrammed. Therefore, Kirisun has
specially designed a set of Chinese/English programming software
KSP8000 with friendly interface, convenient operation and
visualized display for setting functional parameters of the radio.
Steps for setting the functional parameters of the radio by PC
are as follows:
A. Install KSP8000 on the PC.
B. Connect the radio to the serial port of the PC with the
special programming cable (KSPL05). Refer to the figure below.
Figure 5.1
C. Turn the computer power ON.
D. Turn the radio power ON.
E. Run the KSP8000 programming software by double
clicking on its executive program.
F. Click “Program” in the main menu of KSP8000, and click
“Read from radio” in the pull-down menu to read parameters of
the radio to the computer; click “Write to radio” in the pull-down
menu to write parameters in the computer to the radio.
G. The following parameters can be set by using KSP8000
according to requirements of the user:
