Ensure that 28 volts dc and 115 volts ac power is being supplied to the system. Check that the vertical (stabilization) gyro is erected. Vary the external panel lighting voltage (dim control) for maximum panel brightness.

    Telephonics Corporation A D A R Y S T E M S I V I S I O N Adjust the TILT control up (+ degrees) in small increments until a clear picture develops of any local weather. Close-in ground targets may also appear in the display. (In bottom-mounted antenna installation, this test may not be possible.) Repeat TILT control adjustment to check remaining ranges.
