Leg not smoothed - The upcoming leg is too short for smooth
waypoint transitions. 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 GNC 250 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 inaccu-
rate altitude will directly translate into inac-
curate position information.
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 GNC 250 has detected excessive drift in its
internal crystal oscillator which may result in
longer acquisition time. The unit should be taken
to an authorized service center immediately.
Poor GPS coverage - The GNC 250 cannot acquire sufficient satel-
lites necessary to provide navigation.
Prox alarm-press NAV - Your craft has penetrated the alarm circle of a
proximity waypoint. Press NAV to see the bearing
and distance to the proximity waypoint.
Proximity overlap - The circles defined by two proximity way-
points overlap. When entering the area of the
overlap, the GNC 250 will warn you of the
closest proximity waypoint, but not both.
You should be certain this condition is
desirable.
Proximity wpt locked - At least one proximity waypoint is locked
because the waypoint has been removed
from the Jeppesen NavData®, the data card
is missing, or the data card has failed.
Proximity wpt moved - One or more proximity waypoints were
moved at least 0.33 arc minutes due to a
database change.
Proximty wpt deleted - One or more proximity waypoints were
deleted while receiving data from the PC
Interface Kit.
Pwr down and re-init - The GNC 250 is unusable until power has
been cycled and the unit re-initialized.
Abnormal satellite conditions may exist.
