call is addressed to this radio. As a
result, the receiver will display the
Sender ID number on the display and
generate a call melody. There are five
different call melodies to let the user
determine who is transmitting a call
(Please refer to the call melody note

After Direct Call transmission is
completed, the radio (Transmitter and
Receiver) will change its CTCSS code

The Private code is used to avoid
interruption from the original Channel
