1. Press PROGRAM then LIMIT. Lo appears.

2.Enter the lower limit of the frequency range you want to search.

3.Press E then LIMIT. Hi appears.

Note: If the frequency you entered is not a valid frequency, Error appears. Enter a different frequency then repeat Step 3.

4.Enter the upper limit of the frequency range.

5.Press E then press LIMIT. Lo and the lower limit frequency appear.

6.Press ▼ to search from the upper to the lower limit, or ▲ to search from the lower to the upper limit. The current monitor memory number flashes.

7.When the scanner stops on a transmission you want to save, press MON (CLR) to store the frequency in the current monitor memory. The monitor memory number stops flashing.

8.Press either ▼ or ▲ to continue the search. If you saved a fre- quency in a monitor memory, the monitor memory number advances by one and starts flashing again. (If the last monitor memory was 10, the scanner returns to monitor memory 1.)
