the host radio will not be changed. When pressing the PTT button,
the green light flashing twice and one beep mean to activate the

inactivate the clone mode. When entering clone mode, the default
setting of the sub radio receiving data is to prohibit wired clone
mode.
3) Press the MONI key, red light flashes, and it starts cloning.
After cloning is finished, the red light turns dim.
Note:
You can activate/inactivate the wired clone mode. Short
circuit the two SELF terminals, enter the model setting mode and
then the manually adjustment function and wired clone function will
become active automatically. If you press the MONI key at this
moment, the wired clone function will be prohibited.
You can also activate/inactivate the wired clone mode by PC
