The saved call list shows all ten storage locations. If no calls have been received, the saved call list is
empty and the pre-stored list is available upon entering the individual call mode.
When in the saved call list, pressing MENU toggles the time stamp ON and OFF. The time stamp
indicates how long ago the call was received. The display indicates this information as HH:MM:SS where
HH = hours, MM = minutes and SS = seconds.
When in the pre-stored list, pressing MENU toggles the Logical Identification (LID) ON and OFF.
6.20.3 Send an Individual Call
The following procedures describe how to initiate and complete an individual call.
1. To select a previously stored individual, select the I-Call mode from the menu or press IND followed
by the
ramp control to scroll through the list of stored individuals. The selection mode rules
apply. While in the individual call list, the menu key toggles the display between the call name and
the unit ID number. If the individual is not stored in this list but the individual’s unit ID is known, it
can be entered directly from the keypad.
2. Press the PTT button; the radio performs the necessary signaling to obtain a communication channel.
When the signaling is complete and the radio is clear to transmit, TX indicator turns ON and the
channel access tone sounds. Line 1 shows the called individual's name if found in the list of stored
individuals or ID followed by the logical ID number of the unit being called. The message *INDV*
displays on line 2. Proceed with the call.
6.21 STATUS/MESSAGE OPERATION (P25 TRUNKED)
Status and message operation is possible with either the Scan or System version of the Unity mobile radio
unit. The following procedure is applicable for the System version. For operation with the Scan version,
the four primary keycaps must be reconfigured and pre-programmed for status/message operation.
6.21.1 Status Operation
Status operation permits the transmission of a pre-programmed status condition to the P25 Trunked site.
To send a status condition, press the STS button (keylight comes on) then press one of the number
buttons (0-9) to select the pre-programmed status. If no status has been programmed for the selected
number button, the radio displays NO ENTRY and the radio sounds a low tone. A valid selection permits
the status text to appear in the display for a pre-programmed time. After the time-out expires or the
MENU button has been pressed (the MENU button overrides the time-out period), the status is selected
and is transmitted to the site or stored in the radio memory where it can be polled by the site at a future
time. If the site receives the status properly, when transmitted or polled by the site, a high-pitched tone
sounds and the keylight associated with that status remains lit. If the site does not receive the status
properly, a low-pitched tone sounds and the keylight associated with the status blinks.
