Garmin GNC 300XL TSO - Manual (Page 129)

Invald CPA wpt _____ - The closest point of approach cannot be created
from the waypoint entered on the CPA Page.
This occurs when the computed point does not
fall on one of the route legs, or when a unique
waypoint name for the closest point of approach
cannot be found.
Invalid copy route - A non-empty route was selected for a copy
operation. A route must be empty before
another route can be copied to it.
Invalid CPA route - The selected route contains less than two way-
points and cannot be used for CPA operations.
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 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 nm of an SUA, and
your current course will not take you inside.
Need alt - press NAV - The GNC 300XL 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 GNC 300XL has failed to receive altitude
data from the parallel input. Check the I/O
settings and/or the installation. If enough
satellites are available for a 3D position fix,
no pilot action is required, providing no
RAIM warnings are present. If only a 2D fix
is possible, the pilot should maintain the
GPS altitude within 1,000 feet of pressure
altitude, using the position page.
No course input - The GPS SEQ switch is set to the HOLD
position and has no selected course input
from the CDI/HSI. Check the state of config-
uration switches if installed, or check the
CDI/HSI unit.
No DGPS position - Not enough data is available to compute a
differential GPS (DGPS) position.
No RAIM FAF to MAP - RAIM is predicted to NOT be available from
the final approach fix to the missed approach
point. The approach is no longer active.
No RTCM input - DGPS data, in an RTCM SC-104 format, is
not available.
