Direct Call Operation
Atthesametime,theotherradio
checks the receiving Direct Call data at
the same Channe
land CTCSS code. If
the Caller ID number matches its Home
ID (Receiver ID number) or equivalent
Group Call, then it recognizes that the
call is addressed to this radio. As a
result, the receiver will display the
Sender ID number on the LCD and
generate a call melody. There are five
different call melodies to let the user
determine who is transmitting a call.
After Direct Call transmission is
completed, both radios (Transmitter
and Receiver) will change their CTCSS
code setting to Private code for 15
seconds. It is used to avoid interruption
from original Channel and CTCSS
code. During the 15-second period,
both radios can only transmit and
receive voice message at the original
Channel with Private Code. Also, the ID
icon on both radios flashes on the
display to indicate this 15-second
period. When the conversation is made
within this period, the 15-second time
out is extended for another 15 seconds.
To exit the 15-second period, press
CALL or wait for the 15 second time
out.
