I-Call (Motorola/EDACS)
I-Calls are direct unit-to-unit transmissions that are not heard by other system users. Your BC780XLT can receive these transmissions. How you receive I-Calls depends on whether you are in Search or Scan mode. During I-Call reception the display will show the Unit ID number of either the transmitting or receiving mobile unit, not a talkgroup. Unit IDs will display differently according to the type of trunked system, and will replace the 'n's shown here. EDACS and MOTOROLA TYPE 1 MOTOROLA TYPE 2 innnnn 7nnnnnn
Hint -- There are thousands of Unit IDs in typical systems, but relatively few I-Calls at a given moment, so it is normally best to let the scanner to receive any I-Call without trying to specify particular units.
I-CALLS IN SEARCH MODE
In SEARCH mode, the scanner default is that I-Call reception is OFF. This means that I-Calls will not be received until you program them to be ON. You have three choices for controlling I-Call reception. Through the Menu system, go to TRUNK DATA / BANK NO / I-CALL , and make your selection. The menu choices are:
1 OFF 2 ON
I-CALLs TALKGROUPS Not received Received normally YES Received normally
3 ONLY YES
NOT RECEIVED
This is the BC780XLT default Use this choice to receive I-Calls together with normal talkgroup traffic. Use this setting to listen to I-Calls, and block all talkgroup reception. For quick access to this mode, press then SRCH.
In I-Call ONLY mode, the display will show I-CALL, to warn that only I-Calls will be received. You can HOLD any I-Call ID. Because you can only hold on one ID, and there are two IDs involved in any I-Call communication (the transmitting and the receiving units), you might not hear the full conversation, but you probably will.
