INITIALIZING THE SCANNER

If the scanner's display locks up or does not work properly after you connect a
power source, you might need to initialize the scanner.
Important: This procedure clears all information you stored in the scanner's
memory. Initialize the scanner only when you are sure the scanner is not work-
ing properly.
1. Turn off the scanner, then turn it on again. WELCOME SCAnnInG rECEIVEr
appears.
2. Press 0 while welcome message. Then press 1. InItIAL appears about 2
seconds. After 2 seconds, YES —Ent and No —CLEAr appears alternately.
3. Press ENT. WAIt appears for about 2 seconds.
Note: Do not turn off the scanner until the initialization is complete. When the
initialization is complete, 1CH 000.0000 appears on the display.

A GENERAL GUIDE TO SCANNING

Birdie Frequencies

Every scanner has birdie frequencies. Birdies are signals created inside the
scanner's receiver. These operating frequencies might interfere with transmis-
sions on the same frequencies. 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.
To find the birdies in your individual scanner, begin by disconnecting the an-
tenna and moving it away from the scanner. Make sure that no other nearby
radio or TV sets are turned on near the scanner. Use the search function and
search every frequency range from its lowest frequency to the highest. Occa-
sionally, the searching will stop as if it had found a signal, often without any
sound. That is a birdie. Make a list of all the birdies in your scanner for future
reference.

FREQUENCY CONVERSION

The tuning location of a station can be expressed in frequency (kHz or MHz) or
in wavelength (meters). The following information can help you make the nec-
essary conversions.
1 MHz (million) = 1,000 kHz (thousand)
