Operating Instructions
Manual Frequency Selection
The Air Scan
®
will receive Aviation frequencies (117.975 MHz to 137.000 MHz), AM frequencies
(520 kHz to 1710 kHz) and FM frequencies (88.0 MHz to 108.0 MHz). The frequency currently
selected and band are always displayed on the Air Scan's screen.
From the example above, the Air Scan is receiving 122.975 MHz. To manually enter a desired
frequency, first select the proper source (AIR, FM or AM) by pressing the
SOURCE
button. The
current band will be displayed on the right side of the Air Scan's screen.
Once you have selected the desired band, enter the frequency using the numeric keypad.
The Air Scan will return to the previous frequency if there is a pause of five seconds or more
between button entries while entering a new frequency. The
Clear
button may be pressed any time
prior to entering the last digit to clear the digits entered and return to the previous frequency.
Any frequency outside of the range of the current band will not be accepted. The Air Scan will
beep when such a digit is entered. For example, starting any frequency selection with a number
other than 1 on the Aviation band or attempting to place a 0, 4, 5, 6, 7, 8 or 9 in the second digit on
the Aviation band will result in a beep.
