Beyond the Basics
Select a size code for a block, then press
SRCH and listen to the conversations. If
you are receiving most of the replies, then
you have probably selected the right size
code and can program the next block of
the map. There are 16 preset fl eet maps
to choose from, and it is best to start with
these when setting up a Type I or hybrid
trunk scanning bank.
If none of the following preset fl eet
maps allow you to follow complete
conversations, then you probably need
to program your own fl eet map (see
“Programming a Fleet Map”).
