I-Call (Motorola/EDACS)
I-Calls are direct unit-to-unit transmissions that are not heard by other system users. Your UBC780XLT 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 | innnnn |
MOTOROLA TYPE 2 | 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:
| | I-CALLs | TALKGROUPS | | |
1 | OFF | Not received | Received normally | This is the UBC780XLT default |
2 | ON | YES | Received normally | Use this choice to receive I-Calls |
| | | | together with normal | |
| | | | talkgroup traffic. | |
3 | ONLY | YES | NOT RECEIVED | 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.
☞In SEARCH mode, when you hear an interesting I-Call, you can enter the instant
shortcut 
then SRCH to enter I-Call ONLY mode. This blocks all talkgroup traffic and lets you hear just the I-Call. To return to normal reception, you must use the Menu system to select the ON or OFF option.
Note: When storing I-Call IDs, remember that the ID will be for only one of the units -- either the transmitting or receiving unit. Unless you specifically want to receive a certain ID, it might be better to use the special code in the HINT below.
