SEARCHING FOR AND TEMPORARILY STORING ACTIVE FREQUENCIES

You can search for frequencies using a limit or direct search, then tempo- rarily store frequencies into monitor memories.

Limit Search

A limit search lets you search for ac- tive transmissions within a specified range of frequencies.

Note: You can also use the scan- ner’s delay feature while using a limit search (see “Using the 2-Second De- lay” on Page 27).

Follow these steps to search for ac- tive frequencies using a limit search.

1.Press PGM, then LIMIT. Lo and a frequency appear.

2.Using the number keys, enter the lowest frequency (including the decimal point) you want to search within the desired fre- quency range, then press

ENTER.

Note: If you enter an invalid fre- quency, Error appears. To cor- rect this, simply repeat the step.

3.Press LIMIT. Hi and a frequency appear.

4.Using the number keys, enter the highest frequency you want to search within the desired fre- quency range, then press

ENTER.

5.Press D to search upward from the lower to the upper limit, or press — to search downward from the upper to the lower limit.

-L-, SEARCH, and s or t appear, and the next available monitor memory flashes.
