5.4 REPLACEMENT
PROCEDURES
5.4.1 Data Cards
Remove all data cards from the unit before replacing parts. Remove the cards with the power
turned off.
Jeppesen Cards
To insert the NavData® or Terrain Data Card (Figure 5-2):
1.
Place the card into the appropriate card slot with the label facing to the left and the swing
arm handle at the bottom front.
2.
Press the data card into place until it seats on the internal connector and the front of the
card is flush with the face of the unit.
3.
If the swing arm handle is up, gently lower the handle and push it into place—flush with
the face of the unit.
To remove the NavData® or Terrain Data Card (Figure 5-2):
1.
Gently press on the tab—using a slight upward motion—at the front center of the data
card. This partially deploys the swing arm handle.
2.
Rotate the swing arm handle upward (and outward) until it locks into place, perpendicular
to the face of the unit.
3.
Grasp the top and bottom surfaces of the swing arm handle between your thumb and
forefinger, and pull directly away from the face of the unit to remove the data card.
