SELECTED COURSE
Select 150° on the CDI/HSI that is connected to the 500 Series unit's MAIN OBS inputs. The
SELECTED COURSE field should indicate near to 150° and a Calibrate to 150°? field appears.
Selecting this field calibrates the 500 Series unit to match the input source. Verify OBS operation by
checking that the course displayed on the 500 Series unit is within 2° of the selected course. Do this at 30°
intervals around the OBS card.
If it is desired to ignore a selected course input (either analog resolver or ARINC 429) for GPS operation in
OBS mode, press MENU on the MAIN CDI/OBS CONFIG page and select "Ignore SEL CRS or GPS?".
When OBS mode is selected, the selected course is entered on the controls of the 500 Series unit. If
ignoring the selected course input such that the VOR valid flag is dependent only on a valid VOR signal,
with lateral deviation calculated by another display device, press MENU on the MAIN CDI/OBS CONFIG
page and select "Ignore SEL CRS for VLOC?".
