Receiving a Unit Call (All Types)
To receive a Unit Call:
1
When an unit call is received, “CALL RECVD” (Standard Control Head) or “Call
Received” (Lightning Control Head) is displayed and the call tone sounds once. The
unit ID of the calling mobile is displayed. The display toggles between “CALL
RECVD” (Standard Control Head) or “Call Received” (Lightning Control Head) and
the calling ID. If programmed, the tone sounds until answered or timer expires.
2
To answer the call, select the menu parameter, press the Unit Call soft button
(Lightning Control Head only), or option key and then the PTT switch and begin
speaking. More information follows:
- If the PTT switch is pressed before the Unit Call key, the call is transmitted as a
group call.
- If unit calls are not permitted (the Unit Call option key is not programmed), press the
Call Response option switch to respond.
- The call must be answered within 20 seconds or it is automatically terminated.
- If the system is busy when a response is made, “BUSY” is displayed and the busy
tone sounds.
Note
To ignore a received call (on a P25 Trunking system), the user can press the select knob
on the mobile radio after a radio receives the unit call. This sends a unit call answer
response to the system, denying the call from the radio. The system will repeat this, and
the initiating radio immediately displays “No Answer.”

Telephone Calls
The telephone call feature allows telephone calls to be placed and received over the public
telephone system using your radio. The type of call (secure/clear) is determined by the
mode selected by the Clear/Secure option switch or the menu parameter selected.
Telephone calling is programmed to operate in one of the following modes:
• Disabled (telephone calls not available).
• Answer-only capability.
• List only - Telephone numbers can be selected from a preprogrammed list only (direct
entry as follows is not allowed).
• Unlimited - Telephone numbers can be selected from a list and also dialed directly
using the keypad on the Digital Keypad Mic.
