Uniden America Corporation UB315 사용자 설명서

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

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 receive any I-Calls
without trying to specify particular units.

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

SCAN OPTION 

- 

TRUNK 

- select bank number - 

I-

CALL

, and make your selection. The menu choices are:

You can HOLD any I-Call IDs. 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 

(decimal key)

then RSM 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.

You can store I-Call IDs in Scan Lists, just like talkgroup IDs,
for use by ID Scan and Manual modes. To program a specific
I-Call Unit ID into a Scan Lists:
