CONTROLS
TILT Rotary control used to select tilt angle of antenna beam with relation to earth
plane. Tilt range is 15 degrees upward to 15 degrees downward.
SLV An annunciator centered on the lower edge of the panel. This annunciator is
used in a dual controller installation and lights whenever this controller is in the
OFF mode and the opposite side controller is in any mode except OFF.
FULL/WX On DC-550 EFIS display controller. Two-position rotary switch selects weather
or map display on either primary flight display (PFD). WX selects arc mode as
well as adds weather to the display.
WX On MC-800 multifunction display controller. Selects radar weather mode for
display on the multifunction display(MFD). If MFD is in PLAN mode, selecting
MAP mode will force the display into the MAP mode for weather display.
MODE SWITCH Six-Position Rotary Switch
OFF Removes power from the system.
SBY Standby. System will warm up but antenna is stowed and transmitter is disabled.
WX Places system in the operational mode selected by FULL/WX switch on the
DC-550 EFIS display controller.
GMAP Places system in ground mapping mode. Ground targets are enhanced. Do not
use GMAP for weather detection, because weather type targets are not
calibrated in GMAP mode.
FP Flight Plan. Provides extended range display of navigational data.
TST Activates the self-test mode and displays a test pattern. Transmitter is on and
radiating.
GAIN Rotary control used to adjust sensitivity of radar receiver. Receiver gain is fixed
and calibrated in the PRESET position. Selection of REACT (RCT) overrides the
gain control setting causing the receiver gain to be fixed and calibrated.
RANGE A two-pushbutton range selection system permits range selection from 5 to 300
nautical miles full scale in the ON mode, or 5 to 1200 nautical miles in the Flight
Plan mode. The UP arrow button selects increasing ranges while the DOWN
arrow selects decreasing ranges. 100-nautical mile range is presented when
system is initially turned on. The last range selected will be remembered when
switching between ON and FP. WX range overrides the RNG/INC/DEC switch
on the MC-800 multifunction display controller when WX mode is selected on
that controller.
