4 When the call is finished or if it is not answered, end it by pressing the (Clear)
button.
6.3.3 Receiving a Unit Call (All Types)
When a unit call is received, “Call Recvd” is displayed and the call tone sounds once.
To answer the call, press the Unit Call option button or select that menu parameter and
then press the PTT switch and begin speaking. The unit ID of the calling radio is
displayed. More information follows:
- If the PTT switch is pressed before the Unit Call option button, the call is transmitted
as a group call.
- If unit calls are not permitted (the Unit Call option button/menu parameter is not
programmed), press the Call Response option button or select that menu parameter to
answer the call.
- Ring times for both Tx and Rx radios are programmable in P25 Trunking, which sets
the maximum ring time of the target radio when receiving phone and unit-to-unit
calls. When this time expires, the call is automatically discontinued. Times of 61 to
120 seconds can be programmed.
- The Unit Call Initiate Ring parameter sets the maximum time the initiating radio rings
when placing a unit call (phone calls not included). Ringing stops if the target radio
answers before this timer expires. Times of 1 to 255 seconds can be programmed.
- If the system is busy when a response is made, the busy tone sounds.
6.4 Telephone Calls
The telephone call feature allows telephone calls to be placed and received over the public
telephone system using your radio. For P25 Trunked/Conventional/Smartnet/SmartZone
Telephone Calls, the Land Mobile Radio System must be connected to a telephone system.
Users should check with the System Administrator to see if Telephone Calls are allowed
on their system. Telephone calls are programmed to operate in one of the following
modes:
• Disabled.
• Answer-only capability.
• List only - Telephone numbers can be selected from a pre programmed list only (direct
entry using the keypad is not allowed).
