USING THE LIGHT
While the scanner is on, press LIGHT to light the display for 5 seconds.
Press any key other than LIGHT while the backlight is on to keep the
display lit for another 5 seconds. To turn off the backlight before it
automatically turns off, press LIGHT.
TURNING THE KEY TONE ON/OFF
Each time you press any of the scanner's keys a tone sounds to verify that
the scanner has correctly accepted your entry.
To turn the scanner's key tone on or off, first turn off the scanner. Then
while you press and hold 2 and ENTER, turn VOLUME OFF/MAX clockwise until
the display appears.
USING THE KEYLOCK
Once you program your scanner, you can protect it from accidental program
changes by sliding KEYLOCK to the right.
The only controls that operate in the keylock mode are SCAN, MANUAL, LIGHT,
VOLUME, and SQUELCH. When you want to change the scanner's programming,
slide KEYLOCK to the left.
CHANGING THE AM/FM/WFM RECEIVE MODE
The scanner scans in the following modes:
AM (amplitude modulation) - Used in aircraft bands and
amateur radio band.
FM (narrowband frequency modulation) - Used in action bands such as
police, fire, ambulance, amateur
radio, etc.
WFM (wideband frequency modulation) - Used in commercial FM broadcasts
and television sound.
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
30.0000 - 87.4950 FM
87.50000 - 107.9500 WFM
108.0000 - 136.9750 AM
137.0000 - 224.9950 FM
225.0000 - 399.9875 AM
400.0000 - 512.000 FM
760.0000 - 999.9875 FM
The preset mode is correct in most cases. However, some ham radio and
military aircraft 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.
