Appendix A: Data Card Use The Jeppesen NavData Card, and the Terrain Data Card (if applicable) supplied with the GNC 420 can be installed or removed when the GNC 420 is on or off. If the NavData Card is not present when the unit is turned on, a 'No Jeppesen Aviation Database - Limited to user defined waypoints' message appears on the Database Confirmation Page. If the NavData Card is removed during operation, a 'Data card removed - Unit will restart in 30 seconds' warning is displayed. A counter begins to count down and, if the card is not replaced within 30 seconds, the GNC 420 automatically re-initializes. Pressing the ENT Key will manually re-initialize the unit.
