2.5.5 PRIVATE CONVERSATION II CALLS

General

Private calls allow you to place a call 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 the Enhanced Private Conversa- tion mode was described in Section 2.5.4, and opera- tion in the Private Conversation II mode is described in the following information.

The Private Call option switch is required to place these calls, and either that switch or the Call Response option switch is required to receive them. Proceed as follows.

Placing a Private Conversation II Call

This call can be initiated by selecting the unit ID from a call list (list entry) or by directly entering it using the keypad (direct entry). Direct entry is avail- able with full keypad (15-key) models only. Proceed as follows:

The tag (alias) of the last ID called is displayed if it matches an ID in your call list. Otherwise, the last ID called is displayed.

2.Enter the index of the desired ID if you know it or

scroll through the list using the and keys until you find the desired ID. Press the CLR key to

cancel the call.

If the entered ID is valid, the display indicates the alias of the ID if it matches an ID in your call list. Otherwise, the ID you entered continues to be displayed. Wait approximately 1 second and then begin talking. Any of the following conditions may then occur.
