•If you have not stored frequencies into any channels (see “Storing Active Frequencies” on Page 27), the scanner does not scan.

You can manually store frequencies you already know into the scanner’s channels. You can also store frequencies you found using band search directly into channels. You can also store a frequency into a monitor memory then store it into a channel.

Good references for active frequencies are the RadioShack Police Call Radio Guide Including Fire and Emergency Services, Aeronautical Frequency Directory, and Maritime Frequency Directory. We update these directories every year, so be sure to get a current copy.

If you do not have a reference to frequencies in your area, follow the steps in “Band Search” on Page 29 or “Direct Search” on Page 31 to search for transmissions. See also “Guide to the Action Bands” on Page 41.

Manually Storing Frequencies

If you know a frequency you want to store, you can store it manually.
