Switches and controls on the lower part of the instrument panel and the
marker beacon/ audio control panel may be lighted by electroluminescent
panels which do not require light bulbs for illumination. To utilize this
lighting, turn on the NAV light switch and adjust light intensity with the
small (inner) control knob of the concentric control knobs labeled EL
PANEL, ENG-RADIO.
Instument panel flood lighting consists of five red flood lights on the
underside of the antiglare shield, and two red flood lights in the forward
part of the overhead console. The lights are utilized by adjusting light
intensity with the large (outer) control knob of the concentric control
knobs labeled POST, FLOOD. Flood lighting may be used in combination
with post lighting by adjusting post light intensity with the small (inner)
control knob.
The instrument panel may be equipped with post lights which are
mounted at the edge of each instrument or control and provide direct
lighting. To operate the post lights, adjust light intensity with the small
(inner) control knob of the concentric control knobs labeled POST, FLOOD.
To combine post and flood lighting, adjust flood light intensity with the
large (outer) control knob.
The engine instrument cluster, radio equipment, and magnetic com-
pass have integral lighting and operate independently of post or flood
lighting. The light intensity of instrument cluster, magnetic compass, and
radio equipment lighting is controlled by the large ( outer) control knob of
the concentric control knobs labeled EL PANEL, ENG-RADIO.
If
the
airplane is equipped with avionics incorporating incandescent digital
readouts, the ENG-RADIO (large outer) control knob controls the light
intensity of the digital readouts. For daylight operation, the control knob
should be rotated full counterclockwise to produce maximum light inten-
sity for the digital readouts only. Clockwise rotation of the control knob
will provide normal variable light intensity for nighttime operation.
If
the airplane is equipped with a Cessna 400B Integrated Flight
Control System individual dimming control of both the white and the green
Mode Selector panel lamps is provided by the concentric control knobs
labeled IFCS, WHITE, GREEN. A push-to-test feature is incorporated into
the small (inner) knob to test for proper green mode selector lamp opera-
tion. ·
The control pedestal has two integral lights and, if the airplane is
equipped with oxygen, the overhead console is illuminated by post lights.
Pedestal and console light intensity is controlled by the large (outer)
control knob of the concentric control knobs labeled POST, FLOOD.
Map lighting is provided by overhead console map lights and an
