Individual call/ group call
Individual call: Using programming software, set the
transceiver's individual ID code. This can be any code
of up to 15 characters, using the digits 0-9, *, #, A, B,
C, and D. The default transceiver individual call ID
code is 1000.
Group Call: Using a group call character in any part
of a radio calling sequence will call all radios in a
specific calling group. The only radios in the group
that will not automatically respond to a group call are
transceivers which are either set to selective call only
or those which have receive or receive/transmit inhibit
enabled. The group character may be *, #, A, B, C, or
D. The default group character is A.
