Using Trunk Scanning Scan Delay
Sometimes a user might pause before replying to a
transmission. You can set the scanner to hold on an ID
for 5 seconds to wait for a reply. That way, the scanner
continues to monitor the ID for 5 seconds after the
transmission stops before resuming scanning.
Press 
DELAY to turn trunk scanning scan delay on or
off. 
DLY appears when the scan delay is set to on.
Note:
 If you consistently miss responses even with
scan delay turned on, change the default system type
or...

CHANNEL ACTIVITY BARS
Your scanner displays up to 20 channel activity bars for
the stored frequencies in a bank. These bars indicate
the activity taking place on a trunked system. By ob-
serving these bars, you can see how many frequencies
are being used and generally monitor how much com-
munication traffic occurs.
Each frequency you store in a trunking bank has a cor-
responding activity bar. However, there are only 20
bars for a possible maximum of 50 frequencies. If the
trunk system contains more...

up to 10 IDs, for a total of 50 IDs for each trunk scan-
ning bank. If you use all the banks as trunking banks,
you can store 1000 IDs. 
Talk group ID lists help you to organize trunking system
users into categories. For example, you might use List
1 for police IDs, List 2 for fire department IDs, List 3 for
emergency medical service IDs, and so on. Once you
store all the IDs in a list, you can scan them just as you
scan conventional channels. You can program IDs into
talk group ID lists manually,...

Priority Talk Group ID Scanning
You can assign a priority to a favorite ID so during
scanning the scanner checks that ID more frequently
than the others in the list. Each of the five memory loca-
tions reserved for storing lists (see “Using Talk Group
ID Lists” on Page 52) can have only one priority ID, and
the ID assigned that priority in List 1 has the highest pri-
ority of all.
To assign a priority to an ID, press 
PROG. Enter the de-
sired ID number (list number and location number),
then press...

Subfleet information is included with the frequency list
for a Type I system. To enter the provided map, see
“Programming a Fleet Map” on Page 60.
Note:
 Review the content of website

ner.com 
to locate suitable fleet map information.
If you do not already know the size codes used, you will
have to guess. Since you do not have to figure out all
the blocks at one time, this is not as hard as it might
seem. Select a size code for a block, then press 
SRC.
