CHANGING THE AM/FM/WFM RECEIVE MODE
The scanner is preset to the most common AM/FM/WFM receive mode for each
frequency range. The preset modes are:
Frequency Band (MHz) Receive Mode
25.000-87.495 FM
87.500-107.950 WFM
108.000-136.975 AM
137.000-224.995 ` FM
225.000-399.9875 AM
400.000-1300.000 FM
The preset mode is correct in most cases. However, some ham radio broadcasts do
not operate in the preset mode. If you try to listen to a broadcast when the scanner is
not set to the correct receive mode, the broadcast might sound weak or distorted.
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.
Note: If you change any frequency band's receive mode during 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.
To return to the default settings, press and hold down CL/DELAY, then press
AM/FM/WFM.
USING THE ATTENUATOR
To reduce interference or noise caused by strong signals, you can reduce the
scanner's sensitivity to these signals. Press ATT until ATT appears on the display to
reduce the scanner's sensitivity.
Note: If you turn on this feature, the scanner might not receive weak signals.
To turn off the attenuator, press ATT again. ATT disappears from the display.
TURNING THE KEY TONE ON AND OFF
Each time you press any of the scanner's keys, the scanner sounds a tone.
