6.5 PRIVATE (UNIT-TO-UNIT) CALLS
NOTE: With P25 Trunked operation, these calls are
called Unit Calls, and they function the same as
Enhanced Private Conversation calls described in the
following information.
6.5.1 GENERAL
Private calls allow calls to be placed to a specific
radio unit. Either the Enhanced Private Conversa-
tion™ or standard Private Conversation modes may be
programmed depending on the capabilities of the radio
system. One difference between these call types is that
the Enhanced type provides an indication that the
called radio is not on the air and the standard version
does not. Operation in each of these modes is
described in the following information.
The Private Call option key is required to place
these calls, and either that key or the Call Response
option key is required to receive them. Private calls are
programmed to operate in one of the following modes:
•
