6. Repeatedly press s or t to select the size code for

the first block, then press

.- The next available

7. Repeat Step 6 until you have selected a size code

for each block you want to work with.

8. Press

SRCH

. The scanner exits the trunking pro-

gramming mode, tunes the data channel, then
begins to search using the map you programmed.

Note: If you select size code S-12, S-13, or S-14, these re-
strictions apply:

• 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, the scanner prompts you for

, 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.

Programming a Hybrid System

A hybrid system is simply a Type I system with some of
its blocks designated as Type II blocks. To program a
hybrid system, follow the steps listed in “Programming a
Fleet Map” on Page 49. However, if you want a block to
be Type II, select size code

S-0

in Step 6.
