Programming a Fleet Map
1. Set the scanner for conventional
scanning, then hold down TRUNK
until the scanner beeps twice.
BANK , TRUNK , and the bank
numbers flash.
2. Press a number key to select the
bank where you programmed
Type I trunk frequencies.
3. Repeatedly press ▲ or ▼ until E1
appears, then press E.
4. Press DATA .
5. Repeatedly press ▲ or ▼ until
USr appears, then press DATA .
6. Repeatedly press ▲ or ▼ to select
the size code for the first block,
then press
E . The next available
block appears.
7. Repeat Step 6 until you have
selected a size code for each
block you want to work with.
8. Press SEARCH . The scanner exits
the trunking programming mode,
tunes the data channel, then
begins to search using the map
you programmed.
Note: If you select size code S12,
S13, or S14, these restrictions apply:
• S12 can only be assigned to
Blocks 0, 2, 4, or 6.
• S13 can only be assigned to
Blocks 0 and 4.
• S14 can only be assigned to Block
0.
Since these size codes require multi-
ple blocks, you will be prompted for
the next available block when pro-
gramming a fleet map. For example, if
you assign Block 0 as an S12, the
scanner prompts you for
b2 , the next
block available, instead of b1 . And if
you assign Block 0 as an S14, you
would not see another prompt be-
cause it uses all available blocks.
Programming a Hybrid
System
A hybrid system is simply a Type I
system with some of its blocks desig-
nated as Type II blocks. To program a
hybrid system, follow the steps listed
in “Programming a Fleet Map” on
Page 44. However, if you want a block
to be Type II, select size code
S0 in
Step 6.
Programming the Base and
Offset Frequencies
To properly track Motorola VHF and
UHF trunked systems, you must pro-
gram the applicable base and offset
frequencies for each system.
These settings can be found at
www.trunkscanner.com and similar
frequency resources.
1. Set the scanner for conventional
scanning, then hold down TRUNK
until the scanner beeps twice.
2. Press the number key of the bank
where you want to store the base
frequency.
