FINDING AND STORING ACTIVE FREQUENCIES

Searching the Service Banks

Your scanner contains groups of preset frequencies called service banks. Each service bank is associated with a specific activity (see “Understanding Service Banks/ Banks” on Page 10). You can search for fire/ police, air, ham, and marine transmissions even if you do not know the specific frequencies that are used in your area. Then you can store the frequencies you found into the scanner's channels or monitor memories.

Note: You can use the scanner's delay feature while searching the service banks (see “Using the Delay Function” on Page 20).

The following steps describe the operation of the HAM, FD/PD, and AIR service banks. To listen to the marine bank, see “Listening to the Marine Bank” on Page 19.

1.Press BAND. The last selected band name (such as HAM), SRCH, -b-, the frequency and the group number (if any) appear.

2.To select a different band, repeatedly press BAND until the desired band name appears on the display. After about 2 seconds, the scanner begins searching rapidly up or down in that band for an active frequency.

Notes:

To search through the frequencies, hold down 8 or 9 for a few seconds. The scanner tunes through the frequencies until it finds an active frequency .

To reverse the search direction at any time, hold down 8 or 9 until the scanner reverses the search direction.

To search the band up or down in

small increments repeatedly press and release 8 or 9(see “Service Banks” on Page 11).

To pause the search while receiving a signal, press and release 8 or 9. To continue the search, hold down 8 or 9 for about 2 seconds.

To move quickly up or down through

the frequencies, press and hold down 8 or 9. The scanner tunes through the frequencies until you release 8 or 9.

Use the number keys to select search groups.

3.When the scanner finds an active frequency, it stops searching and displays the frequency's number. To store the displayed frequency in the lowest available channel, press PGM then press ENTER. The channel and frequency flash twice, and the scanner stores the displayed frequency. The scanner then continues to search for frequencies.

Notes:

If there is no empty channel, Ch- FULL appears when you press PGM. To store more frequencies, you must clear some channels. See “Clearing a Stored Channel” on Page 18. To

continue searching after Ch-FULLappears, press and hold down 8 or

9.

If you entered a frequency that is already stored in another channel, - dUPL- and the lowest-numbered channel containing the duplicate
