Radio Shack 20-422 Searching for and Temporarily Storing Active Frequencies, Band Search

Page 15

Follow these steps to manually store a frequency into a channel.

1.If the scanner is scanning, press

MANUAL.

2.Using the number keys, enter the channel number where you want to store a frequency.

3.Press PROGRAM. BANK and the bank number, the selected channel number and L/O (if the selected channel number is empty), and 000.000 (or the previously pro- grammed frequency) appear.

4.Using the number keys, enter the frequency you want to store into that channel, including the decimal point.

Note: Your scanner automatically rounds the entered frequency up to the closest valid frequency. For example, if you try to enter a fre- quency of 151.473, your scanner accepts it as 151.475.

5.Press E to store the frequency. If the channel was locked out, the lockout is removed.

Note: If you entered an invalid fre- quency in Step 4, the scanner dis- plays Error. Press CLEAR, then repeat Steps 4 and 5.

6.To program the next channel in sequence, repeat Steps 3–5. To pro- gram another channel (not in sequence), repeat Steps 2–5.

SEARCHING FOR AND TEMPORARILY STORING ACTIVE FREQUENCIES

You can search for transmissions using either a band or direct search, then tem- porarily store the frequencies for those transmissions into monitor memories.

Notes:

•If you manually tune to a search skip frequency, the display shows L/O (see “Skipping Frequencies/Chan- nels” on Page 19).

•You can use the scanner’s delay feature while using band or direct search. See “Delay” on Page 19.

Band Search

Using band search, you can select a fre- quency band and search for transmis- sions within only that band.

1.Repeatedly press BAND until you see the frequency band you want to search.

The scanner displays ▲ or ▼, the range for each frequency band, b appears, and the number of the cur- rent monitor memory blinks on the display. Then the scanner starts to search the frequencies in the band. When the scanner finds a transmis- sion, it stops and displays the fre- quency until the transmission stops, then the scanner starts searching again.
