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 program-
ming a fleet map. For example, if you assign Block 0 as
an S-12, you will be prompted for b2, the next block avail-
able, 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.
