Private (Unit-To-Unit) Calls

General

Private calls allow calls to be placed to a specific
mobile unit. Either the Enhanced Private Conversa-
tion™ or Private Conversation II™ modes may be
programmed depending on the capabilities of the radio
system. 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:
•
Disabled
•
Answer-only capability
•
List only - Unit IDs can be selected from a prepro-
grammed list only (direct entry using the keypad is
not allowed)
•
Unlimited - Unit IDs can be selected from a list
and also dialed directly entered using the keypad.
Both limited and DTMF keypad models can place
private calls by recalling the unit ID from a prepro-
grammed list as just described. However, only DTMF
keypad models can directly dial unit IDs using the
keypad.
