7: ACTIVITY ID
When activity ID is set to ON, your scanner
receives any transmissions on the ID every
0.5 seconds while scanning.
8:I-CALL (MOTOROLA/EDACS)
Most communications within a trunked system
are group calls where one unit (such as a
dispatcher) communicates with all the units
within his/her group (all the patrol vehicles on
the east side of town, for example). The units
within this group comprise what is typically
known as a talkgroup. There are some
communications which are direct unit-to-unit
conversations where one individual converses
with another individual. The call is initiated by
a radio and is directed to another single radio.
Within the system, no one outside of these
two users hears the conversation.
Your UBC3300XLT defaults to I-CALL OFF
mode. You can hear these conversations by
using this Menu item to turn the I-CALL
function to ON. In Search mode, with I-CALL
ON, you will hear both talkgroup calls and I-
CALLs. You can also set I-CALLs to I-CALL
ONLY during which you will monitor only I-
CALLs in Search mode. You can also
program I-CALL IDs into Scan List memory.
OR
8:ID SCAN LIST (LTR)
When scanning an LTR system you can only
turn Scan Lists OFF and ON when an LTR
talk group that you have entered into memory
is active. To provide you with another method
to turn Scan Lists ON and OFF, you can use
this Menu item which only appears when you
have selected LTR in trunk type.
9:EMERGENCY ALT (EDACS)
In EDACS trunked systems, you can set an
alert for an EDACS transmission received.
Set Emergency Alert to ON, EMERGENCY
flashes on the display and you will hear beep
alerts when you receive an EDACS
emergency transmission.
