Because the GNC 250 relies on a NavData card for most waypoint information,there may be instances when waypoint information is not available for use. Lockedwaypoints exist when a waypoint contained in a route or used as a proximity way-point is not contained on the NavData card, or no card is inserted in the unit. If thiscondition exists, you’ll be alerted with a ‘Proximity wpt locked’, ‘Route wpt locked’ or‘Wpt comment locked’ message when the unit is powered up. The identifier of alocked waypoint will be replaced with a ‘lockd’ message, which indicates you cannotobtain waypoint information or navigate to the waypoint. The identifier of a lockedwaypoint may be displayed by highlighting ‘lockd’ and pressing ENT. Locked way-points may be deleted from routes, the user waypoint list or the proximity waypointslist by following the instructions in the appropriate section.The waypoint scanning feature provides a fast way to scan through airports,VORs, NDBs and intersections in the database by identifier, facility name or city.Waypoint scanning may be used from any blank identifier field in the GPS window.To enter a waypoint by scanning the identifier, facility name or city:1.
