4.3 NAV DATA CARD REMOVAL AND INSERTION
Before disassembly begins, remove the Jeppesen NavData® card supplied with the unit. The
card can be installed or removed when the unit is on or off. Insert the card with the swing arm
handle at the bottom and the label facing to the left (see Figure 4-1).
To remove the NavData Card:
1. Gently press on the tab using a slight upward motion at the front center of the
NavData card. This will partially deploy 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. 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 unseat the connector and remove the NavData card.
To insert the NavData card:
1. Place the card into the NavData card slot, with the label facing to the left and the
swing arm handle at the bottom front.
2. Press the NavData card into place until it seats on the internal connector and the front
of the card is flush with the face of the unit. If the swing arm handle is up, gently
lower the handle and push it into place flush with the face of the unit.
