consider using a frequency guide. Excellent refer- ences for active frequencies are the RadioShack Police Call Guide including Fire and Emergency Services, and Official Aeronautical Frequency Direc- tory. We update these directories every year, so be sure to get a current copy.

Follow these steps to store frequencies into chan- nels.

Press HOLD. Then enter the channel number where you want to store a frequency. Then press FUNC and PGM. The channel number appears.

Use the number keys and ./CLR to enter the frequency (including the decimal point) you want to store.

Press E to store the frequency into the channel.

Notes:

•If you entered an invalid frequency in Step 2, Error appears and the scanner beeps three times. Enter a valid frequency.

•The scanner automatically rounds the entered number to the nearest valid frequency. For example, if you enter 151.473 (MHz), your scanner accepts it as 151.475.
