marine distress frequency, 2182 KHZ.
To select 2182 KHZ, channel the
KFS 586/A to any 1700 frequency and
rotate the large frequency select knob
one click to the right, clockwise. The
KDF 806 will be tuned to 2182. To
fine tune the reception, the small knob
may be used to vary the frequency
between 2180 and 2189.
To return to standard ADF
frequencies rotate the large knob to
the right, clockwise. The fist click will
select the 100 KHZ frequency, an
invalid ADF frequency. The display will
flash and continue to flash until the
second rotation click and a valid
