SCAN LISTS
When you program trunked frequen-
cies into a bank (see “Programming
Trunked Frequencies” on Page 26),
your scanner sets up 5 scan lists into
which you can 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 IDs if you use
all banks as trunking banks!). 
Scan lists help you organize trunking
system users into categories. For ex-
ample, you might use List 1 for police
IDs, List 2 for fire department IDs, List
3 for...

To remove a scan list from active
scanning, use the number keys to en-

SYSTEMS
Your PRO-2050 is set to scan Type II
user IDs...

S2 16 8 64 1
S3 8 8 128 1
Each ID in the block is unique. The
left-most digit is the block number in
the ID. The next two digits identify
which fleet is active, and the last dig-
it(s) (after the hyphen) identifies the
subfleet.
The size codes selected by a Type I
system designer depend on the spe-
cific needs of the system’s users.
Some organizations might want many
subfleets with only a few radios each,
while another organization might want
only a few subfleets, with many radios
each. To scan Type I...
