purposes. A Beat Frequency
Oscillator (BFO) function is provided to
permit these stations to be more easily
identified. Placing the function switch
in either of the BFO positions causes a
1000Hz tone to be heard whenever
there is a radio carrier signal present
at the selected frequency.

Frequency Control

A. Standby Entry

The Standby frequency is read on

the bottom of the display. It may
be tuned by turning the frequency
selector control. Standby
frequency tuning does not affect
the Active frequency. Depressing
the Transfer button causes the
Standby frequency to appear in the
Active, or upper frequency location.
To tune Standby frequency:

1. Tune frequency of station

desired.

2. Push Transfer button
This method permits the pilot to

tune to the desired frequency
without the accompanying noise of
tuning through other stations.

B. Active Entry

The Active frequency is read on

the top of the display. Holding the
transfer button depressed for
approximately 2 seconds causes
the Standby frequency display to
go out. The Active frequency may
now be controlled directly by the
frequency selector control. In this
tuning mode, the station audio is
present, permitting the operator to
hunt for a station by listening to the
audio while tuning. The large outer
knob of the frequency selector
control selects the 100's KHz from
1 to 17, with roll over from 17 to 1,
and roll under from 1 to 17. The
small inner knob selects 10's KHz
when pushed in and 1's KHz when
pulled out. The 10's KHz and 1's
KHz rolls over from 9 to 0 and rolls
under from 0 to 9.

C. Display Flash

Any time the frequency displayed

is below 190, the display flashes.
This is to alert the pilot he has
selected an out of band frequency.

D. X Character

The small X to the right of the

active frequency turns off in the
ADF and ADF/BFO modes only
when the ADF is pointing.
