2.7.5 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 2.7.4, 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 (18-key) models only. Proceed
as follows:
List Entry Method
1. With a SMARTNET/SmartZone channel selected,
momentarily press the Private Call option switch.
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 two-digit 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.
3. Press the PTT switch to initiate the call. The display
then indicates the alias of the destination radio. Wait
approximately 1 second and then begin talking.
Proceed to the bulleted list which follows the next
method for conditions that may then occur.
Direct Entry Method (Full Keypad Models Only)
1. With a SMARTNET/SmartZone channel selected,
press and hold the Private Call option switch until a
tone sounds (approximately 1 second). The last ID
called is displayed.
2. Using the 0-9 keys, enter the ID (all six digits) of the
mobile unit you are calling. To erase the last digit,
press the
key, and to cancel the call, press the
CLR
key.
3. Press the PTT switch to initiate the call. If the
entered ID did not contain six digits, “INVALID” is
momentarily displayed, an error tone sounds, and
the call is not initiated. 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. Any of the following
conditions may then occur.
•
If in the secure mode and your transceiver does not
have the proper encryption key, “KEYFAIL” is
displayed and the call must be made in the clear
mode (selected by the Clear/Secure option switch
if enabled on the channel).
•
If the called party answers and the call is
successful, the person’s voice is heard and the call
is carried on the same as a group call. To end the
call at any time, press the
CLR
key.
•
If the radio system is busy, four low tones sound
and the “BUSY” is displayed. When the system is
no longer busy, the call back tone (four beeps) is
heard and a channel is automatically acquired.
Press the PTT switch to continue the call.
Receiving a Private Conversation II Call
Unit-to-unit calls are automatically received if a
SMARTNET/SmartZone channel is selected. Proceed
as follows:
1. When a call is received, an alert tone sounds and the
caller’s voice is heard. While voice is heard,
“CALL” is displayed.
2. To answer the call, press the Private Call option
switch and then the PTT switch and begin talking.
The alias of the incoming call is displayed if the ID
is in your call list. Otherwise, the unit ID is
displayed.
NOTE: If the Private Call option switch
is not pressed before the PTT switch, a group call is
transmitted on the selected group.
