or the F2 key. If talk group selection has been
disabled on the channel by programming, “NO
LIST” is displayed, a tone sounds, and no change
occurs.
Unit Calls
Unit Calls (also called Individual Calls) can be
placed to a specific radio on a Project 25 channel if the
Unit Call option key or menu parameter is
programmed. This call differs from standard group
calls in that only one mobile instead of entire groups
of mobiles may receive the call. The mobiles that can
be called are preprogrammed by you system operator.
Proceed as follows to transmit and receive a Unit Call:
1. To transmit a unit call, press the Unit Call option key
or select the Unit Call menu parameter. The alias
(tag) of the last Unit Call is displayed.
2. If required, press the Up/Down switch to display the
desired call. The alias and ID of the unit calls that
have been programmed are alternately displayed.
3. Press the PTT switch and begin talking.
4. When a unit ID call is received, two beeps sound (if
tones are enabled), and “Call Rcvd” and the alias or
frequency of the currently selected talk group are
alternately flashed.
The transceiver may also be programmed to display
the alias of the channel on which the call is being
received (if it is not the same as the selected
channel) and/or the ID of the mobile placing the
call.
5. To respond, select the Unit Call mode by pressing
the Unit Call option key or selecting the menu
parameter. The following operation then occurs:
•
If a unit call has been programmed with the ID of
the calling mobile, it is automatically selected. A
response can then be made without changing the
selected channel.
•
If no Unit Call has been programmed with the ID
of the calling mobile, a response may have to be
made in the standard mode.
•
If the call timer times out (set by programming) or
the channel is changed before a response is made,
the unit call mode is exited.
Keypad Programming
NOTE: The Keypad programming feature is available
to Federal Government users only. Users regulated by
the Federal Communications Commission are not
allowed to have this feature.
Introduction
Keypad programming is available on Federal
radios if the Keypad Programming option key or menu
parameter is programmed. It is then selected by simply
pressing that key or selecting that menu parameter.
The keypad programming mode is indicated by
“ZONE CHG” and
in the display.
Keypad programming allows conventional
channel parameters such as the transmit and receive
frequency and Call Guard squelch code to be changed.
In addition, several conventional mode timers can be
changed. It cannot be used to reprogram disabled
channels or any SMARTNET/SmartZone information.
Menu Structure
A menu system is used to select parameters to be
changed in the keypad programming mode. A flow-
chart showing the keypad programming mode menu
structure is located in Figure 6.
When the keypad programming mode is selected
by the Keypad Programming option key or menu
parameter, the first menu parameter “CHNG ZONE”
