Turn-on
Rotate the ON/OFF/VOL knob
clockwise from the detented “OFF”
position. The unit will be activated and
will be ready to operate. Rotation of
this control also adjusts audio volume.
The KR 87 has “audio muting” which
causes the audio output to be muted
unless the receiver is locked on a
valid station.
Frequency Selection
The active frequency (to which
the ADF is tuned) is displayed in the
left side of the window at all times. A
standby frequency is displayed in the
right side when “FRQ” is annunciated.
The standby frequency is placed in
“blind” memory when either FLT
(Flight Time) or ET (Elapsed Time)
mode is selected.
With “FRQ” annunciated, the
standby frequency is selected using
the frequency select knobs which may
be rotated either clockwise or
counterclockwise. Pull the small inner
knob out to tune 1’s. Push the smaller
inner knob in to tune 10’s. The outer
knob tunes the 100’s and the 1000’s
up to 1799.
The standby frequency selected
may then be put into the active
window by pressing the “FRQ” button.
The standby and active frequencies
will be exchanged (flip-flopped), the
new frequency will become active,
and the former active frequency will
go into standby.
Operating Modes
Antenna (ANT) mode is selected
and annunciated when the “ADF”
button is in the “out” position. ANT
provides improved audio reception
from the station tuned and is usually
used for identification. The bearing
pointer in the KI 227 indicator will be
deactivated and immediately turn to
the 90° relative position and remain
there during ANT reception.
The ADF mode is selected and
annunciated when the “ADF” button is
in the depressed position. ADF
activates the bearing pointer in the KI
227 indicator, causing it to move
without hesitation to point in the
direction of the station relative to the
aircraft heading. The compass card
on the KI 227 may be rotated as
desired by using the heading knob.
NOTE: The KI 227-01 or KI 228-01
indicators, when installed with a
Bendix/King KCS 55A Compass
System, have a slaved compass card.
Magnetic heading of the aircraft will
be under the lubber line. The
indication of this compass card
should be compared with that of
the KI 525A master indicator from
time to time. Check especially after
steep bank turns and taxi turns. If a
discrepancy between the two
readings exists, the KI 227-01 or KI
228-01 compass card should be
synchronized to the KI 525A
compass card by rotating the
“SYNC” knob on the indicator.
