Operating Instructions
To perform the following functions you must be in the basic operating
mode of the SP-200. To ensure that you are in the basic operating
mode, press the clear key until the last frequency you entered
manually is displayed.
Manual Frequency Selection
The SP-200 will receive 200 NAV frequencies (108.000 MHz to
117.950 MHz) and 3000 COMM frequencies (118.000 MHz to
142.975 MHz). The SP-200 will transmit on 2280 COMM frequencies
(118.000 MHz to 136.975 MHz). The frequency currently selected is
always displayed in the lower right-hand side of the SP-200’s screen.
From the example above, the SP-200 is receiving 122.975 MHz.
To manually enter a desired frequency such as 118.700 MHz, enter
1 1 8 7 0 0 using the numeric keypad. As each digit is entered, the
flashing cursor moves to the next digit. Six digits are always required
to select a frequency.
The SP-200 will return to the previous frequency if there is a pause of
five seconds or more between key entries while entering a new
frequency. The Clear Key may be pressed any time prior to entering the
fifth digit to clear the digits entered and return to the previous frequency.
Any frequency outside of the range listed above will not be accepted.
The SP-200 will beep when such a digit is entered. For example, starting
any frequency selection with a number other than 1 or attempting to place
a 5, 6, 7, 8 or 9 in the second digit will result in a beep.
