Uniden Receiver Bearcat BC235XLT Operating Instructions

							User Defined Fleet Maps
Type I Programming Information
When a Type I system is designed, the address
information for all the IDs is divided into 8 equal sized
blocks, numbered 0–7. When you program your scanner to
track a Type I system, you must select a size code for
each of these blocks. When you have assigned a size
code to all 8 blocks, you’ll have defined the Fleet Map for
the system you’re tracking. Each size code determines the
number of Fleets, Subfleets, and IDs each block will have.
For example, a size code of S-4 has one Fleet, which is
divided into 16 separate Subfleets, and it has a total of 512
individual IDs.
When a block is assigned a size code, the Fleet or Fleets
created within the block are assigned a Type I ID. The way
these IDs display on your scanner depend on the block
number and the block’s size code. When a Type I ID
displays, the leftmost digit represents the block which
contains the ID. The next two digits identify which Fleet is
active, and the last digit(s) identifies the Subfleet.
The details concerning how the size codes are selected by
a Type I System designer are highly dependent on the
specific needs of the system’s users. Some organizations
may want many subfleets with only a few radios each,
while another organization may want only a few subfleets
with many radios each. Your task is to program your fleet
map with the same size code assignments as the trunked
system. If you do this accurately, you’ll track all the
Fleet-Subfleet combinations used by the system. In other
words, you’ll hear complete communications while
monitoring a trunked system.

							If you don’t already know the size codes used, you’ll have
to guess at them. But since you don’t have to figure out all
the blocks at once, this isn’t as hard as it seems. Select a
size code for a block, and then press
R. Now listen to the
communications. If you decide you are receiving most of
the replies to the conversations with IDs assigned to the
block you just programmed, then you’ve probably selected
the right size code and can work on the next block of the
map.
Finally, for most public safety systems there are some size
codes which are more common. S-3 and S-4 are probably
the most common, followed by S-10, S-11, and S-12.

							Size Code Restrictions
If you select size code S-12, S-13, or S-14, there are some
restrictions as to which blocks can be used for these codes.
S-12 can only be assigned to Blocks 0, 2, 4, or 6.
S-13 can only be assigned to Blocks 0 and 4.
S-14 can only be assigned to Block 0.
Since these size codes require multiple blocks, you will be
prompted for the next available block when programming a
Fleet Map. For example, if you assign Block 0 as an S-12,
you will be prompted for b2, the next block available,
instead of b1. And if you assign Block 0 as an S-14, you
would not see another prompt because it uses all available
blocks.

							Precautions
Before you use this scanner, please read and observe
the following:
EARPHONE WARNING!
Be sure to use only the recommended optional
monaural earphone (EP009). You may also use a 32W
stereo headset. Use of an incorrect earphone or stereo
headset may be potentially hazardous to your hearing.
The output of the phone jack is monaural, but you will
hear it in both headphones of a stereo headset.
Set the volume to a comfortable audio level coming
from the speaker before plugging in the monaural
earphone or a stereo headset of the proper impedance
(32W). Otherwise you might experience some
discomfort or possible hearing damage if the volume
suddenly becomes too loud because of the Volume
Control or Squelch Control setting. This may be
particularly true of the type of earphone that is placed
in the ear canal.
