							ID Lockout
Like conventional scanning, it’s possible to lockout
unwanted traffic. This is particularly important in trunked
systems because in many areas water meters, door
alarms, traffic signals, and other mechanical devices are
assigned IDs just like other users. Also some departments
scramble or encrypt their communications, and you may
want to lock out these unintelligible broadcasts.
To lockout an ID,
press
Owhen the ID
displays.
The ID is locked out,
and the next active ID
displays. You can
lockout up to 100 IDs.
Note:If you lockout an ID in Search mode, it is also
locked out in Scan List mode. Conversely, if you
lockout an ID while in Scan List mode, it is locked
out in Search mode. For information about Scan
Lists see page 46.
Restore a Single ID
To unlock a single ID, follow these steps:
1. Press and hold
O
until you hear two
short beeps.
2. Use
(or)to select
the ID you want to
unlock.
3. Press
O.
The ID is unlocked
and the next locked
ID displays.
4. PressRto return to
the Search mode.

							Restore all IDs
To unlock all locked out IDs at once, follow these steps:
1. Press and hold
O
until you hear two
short beeps.
2. Press
Eto unlock all
the IDs at once.
Note:If you unlock all the IDs, then the Scan List
Memory mode displays. Press
Sto scan the IDs
stored in your Scan Lists or press
Rto return to
the Search mode. For information about Scan Lists
see page 46.
3. PressRto return to

Searching Tips
ID Delay Mode
Use theYkey to select the Delay mode if it’s not
active. This mode holds an ID for 5 seconds while
you wait for a reply. Other groups may use the
system, but your scanner will only look for the ID in
the display.
Note:If you consistently miss responses while in
ID Delay mode, you may need to change the
default system type or change the fleet map you’re
using.

							Hold Mode
PressHto hold on a particular ID in the display.
This is where the trunk tracking effect is really
noticeable. You can hold a specific talk group,
such as fire department on-scene operations, no
matter which frequency the group uses.
ID Monitor Mode
If you press and holdRuntil you hear two short
beeps, you will select the ID Monitor mode.
SRCH
begins flashing in the display, and all active talk
group IDs begin to display in succession. You
won’t hear conversations in this mode, but this is
an excellent way to determine which talk groups
are the most active.
Note:Locked out IDs display during ID Monitor
mode with the
L/0icon turned on.
Channel Activity Indicators
TheBC 235XLThas 20 Channel Activity Indicators to
visually display a trunked system’s activity when you select
delay, hold, scan etc. You’ll always know which
frequencies are in use and how much communication
traffic is occurring.
Each frequency you program in a trunking bank
corresponds to an activity indicator at the top of your
scanner’s display. The way in which the Activity Indicators
display provide you with information about the system
you’re tracking.
44 
						

							nThe indicator which
remains on, even if
when there is no
traffic, represents the
frequency being used
as the data channel.
nIf an indicator turns
on and you don’t hear
a conversation, then
the channel is
probably being used
for a telephone
interconnect call or a
private call. These
calls are not
monitored by your
scanner.
nThe indicator which
flashes when an ID
displays represents
the frequency being
used by the talk
group.
nIf you’re holding on
an ID which isn’t
active, the activity
indicators will turn on
and off as other
groups use the
system.
Note:If more than 20 channels are stored in a
bank, then the indicators represent multiple
channels. For example, if 29 channels are
programmed, the first 9 activity indicators each
represent two channels.

							Scan Lists
Each bank of yourBC 235XLTcan be a trunk tracking
bank or it can be a conventional scanning bank. When you
designate a bank as a trunking bank, your scanner sets up
5 Scan Lists, which are simply lists used to store your
favorite IDs. Each list can contain up to 10 IDs, so you can
store a total of 50 IDs for each trunk tracking bank (500 if
you use all banks as trunking banks!).
Scan Lists help you organize the 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, etc. Once IDs are stored
in lists, you can scan them like you scan conventional
frequencies. You can program your scan lists either
manually or during trunking search mode.
Programming Scan Lists Manually
1. Select the Trunking
bank you want.
2. After the scanner
begins trunk tracking,
press
M.
3. Use

select the Scan List
location you want to
program. For
example, select the

location in the first
scan list.12345678 910

							Fleet Map Programming
If you have programmed a trunk tracking bank and select
R, you will see user IDs display on your screen. Since
the
BC 235XLTdefaults to Type II systems, all the IDs
will appear as numbers. However, if you notice a mix of
odd and even user IDs, for example 6477, 2560, 6481,
6144, 1167, etc., then you are probably monitoring either a
Type I or Hybrid system. See
Types of Trunking Systems
on page 35.
You may also notice that you’re missing responses when
you hold on an active ID. Unlike Type II systems, Type I/IIi
systems require a Fleet Map that sets specific
Fleet-Subfleet parameters. It’s easy to select a Fleet Map
for your scanner; what isn’t always easy is selecting or
programming a map that matches your particular area.
There are 16 preset Fleet Maps listed in the appendix that
you can choose, and these are usually a good place to
start when setting up a Type I/IIi trunk tracking bank. If you
choose a preset map and still have difficulty following
complete conversations, then you’ll have to program your
own Fleet Map.
Selecting Trunking Programming Mode
To change the system type which your scanner monitors,
you must be in the Trunking Programming mode. To select
this mode, follow these steps:
If you are in Conventional Scan mode:
1. Press and hold
T.
You’ll hear two short
beeps and
BANKand
TRUNKwill begin to
flash in the display.
2. Select the trunking
bank you want to
program.
