4.1 User Mode
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 radio.
4.2 Data Programming Mode
The radio has been set before leaving the factory. However,
due to different requirements of users, the radio’s operating
frequencies, channels, CTCSS/DCS, scan, and other functional
parameters should be reprogrammed. Therefore, Kirisun has
specially designed a set of Chinese/English programming software
KSP568 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 KSP568 on the computer.
B. Connect the radio to the serial port of the PC with the
special programming cable (KSPL-09). Refer to the
figure below.
