2. Make sure the aircraft's transponder is in the STBY mode and the DME is turned OFF. Verify all
avionics equipment interfaced with the SKY899 (i.e., GPS, ADC, AHRS, synchro compass, encoding
altimeter) is turned ON and signal condition is valid.
NOTE
After power up, it may take a couple of minutes for the altitude encoder
to return a valid altitude to the transponder and SKY899.
3.
Turn SKY899 ON. The display will show a start-up screen similar to one shown in figure C-2. After
start-up screen appears, rotate the OFF/BRT switch. Verify that clockwise rotation increases display
brightness.
