To change the mode, press AM/FM/WFM. AM, FM, or WFM blinks on the display
to indicate that the displayed receive mode has been changed from the
preset mode.
NOTES: If you change any frequency band's receive mode during a limit or
direct search, the scanner no longer uses any of the preset receive
modes. Instead, the scanner searches for frequencies in all the
bands in the selected mode.
If you change the band mode to WFM during frequency search, your
scanner automatically searches frequencies at 50 kHz steps.
To return to the default settings, press and hold down CLEAR then press
AM/FM/WFM.
For more information, see "Specified Intervals" under "A General Guide to
Scanning."
A GENERAL GUIDE TO SCANNING
Reception of the frequencies covered by your scanner is mainly "line-of-
sight." This means you usually cannot hear stations that are beyond the
horizon.
During the summer months, you might be able to hear stations in the 30-50
MHz range located several hundred or even thousands of miles away. This
is because of summer atmosphere conditions. This type of reception is
unpredictable but often very interesting!

Birdie Frequencies
Birdie are operating frequencies generated and used inside the scanner's
receiver. These operating frequencies could interfere with broadcasts
on the same frequencies and make them difficult or impossible to receive.
If you program one of these frequencies, you hear only noise on that
frequency. If the interference is not severe, you might be able to turn
SQUELCH clockwise to cut out the birdie. The most common birdies to
watch for are:
44.5450 178.1800 267.2750 473.3000 781.2000
84.8800 190.0000 284.1750 474.9000 801.8000
