BendixKing CNI 5000 - Manual (Page 9)

8
The CNI 5000 has two identical NAV
receivers. The following operating instruc-
tions apply to NAV 1 and NAV 2.
Power Up.
Rotate the ON/OFF/VOL/IDENT knob
clockwise from the detented “OFF” posi-
tion. Power will be activated and the unit
will be ready to operate. Rotation of this
control also adjusts NAV signal volume.
NAV voice may be heard when the knob is
pushed in. When the knob is pulled out,
the Ident signal plus voice may be heard.
Frequency Selection.
By rotating the concentric frequency
selector knobs either clockwise or counter-
clockwise, the desired operating frequency
can be dialed into the “STBY” (standby)
window. A clockwise rotation will increase
the displayed frequency number, while a
counterclockwise rotation will decrease it.
The larger selector knob is used to change
the MHz portion of the frequency display;
the smaller knob changes the kHz portion
in 50kHz steps. At either band edge of the
108.00 to 117.95 MHz frequency spectrum,
an off-scale rotation will wrap the display
around to the other frequency band-edge
(i.e., 117.95 advances to 108.95 with the
MHz knob rotation, or 117.00 with the kHz
knob rotation). Remote DME and glides-
lope receivers are also controlled by these
selector knobs.
NAV Frequency Operation.
To tune the NAV receiver to the desired
operating frequency, the selected frequen-
cy is first entered into the “STBY” display
and then activated by pushing the transfer
(flip-flop) button. This will interchange the
frequencies in the “USE” and “STBY” dis-
plays, and the receiver will now be tuned to
the new operating frequency.
Additionally, this feature makes it possi-
ble to pre-select one NAV frequency in the
“STBY” display—and then switch back and
forth between the two frequencies by
pressing the transfer button.
