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.
