Garmin GPS 150 - Manual (Page 83)

Invalid SAR route - The selected route does not contain exactly two waypoints
and cannot be used for SAR operations.
Leg not smoothed - The upcoming leg is too short for smooth waypoint transi-
tions. Expect a rapid change in the CDI.
Memory battery low - The battery that sustains user memory is low and should be
replaced by an authorized GARMIN service center as soon as
possible. Failure to do so may result in loss of stored data,
including all user waypoints and routes.
Near SUA < 2 nm - Your position is within 2 nautical miles of an SUA and your
current course will NOT take you inside.
Need alt - press NAV - The GPS 150 needs altitude input in order to start and/or
continue 2D navigation. Press the NAV key and enter your
antenna altitude on the Position page. The altitude you enter
should be as accurate as possible. An inaccurate altitude will
directly translate into inaccurate position information.
No altitude input - The GPS 150 has failed to receive altitude data from the serializer.
Offset nav cancelled - Offset navigation has been cancelled due to a direct-to
operation or modification of the active route.
Offset nav in effect - Offset navigation mode is in effect.
Ofst too big for rte - The parallel track distance is too large for the active route.
Osc needs adjustment - The GPS 150 has detected excessive drift in its internal crystal oscil-
lator which may result in longer acquisition time. The unit should
be taken to an authorized GARMIN service center immediately.
Poor GPS coverage - The GPS 150 cannot acquire sufficient satellites necessary to
provide navigation.
Prox alarm-press NAV - Your craft has penetrated the alarm circle of a proximity waypoint.
Press
N
to see the bearing and distance to the proximity waypoint.
Proximity overlap - The circles defined by two proximity waypoints overlap.
When entering the area of the overlap, the GPS 150 will
warn you of the closest proximity waypoint, but not both.
You should be certain this condition is desirable.
