Garmin GNS 430 - Manual (Page 177)

169
Heading input failure —The heading selection on the external
HSI’s (or CDI’s) OBS course selector cannot be read properly. Your
GARMIN dealer may need to check the installation.
Inside airspace —Your GPS-calculated position lies within the
boundaries of a special use airspace. This message is automatically dis-
abled within 30 nautical miles of an arrival airport, when an approach
is loaded.
Invalid closest pt of FPL —A closest point cannot be created from
the waypoint entered on the “Closest point of flight plan” window.
This occurs when the selected waypoint is beyond the limits of all legs
in the flight plan, too far away, or when a unique waypoint name for
the closest point cannot be created.
Invalid FPL modification —An attempt was made to modify the
final course segment (FAF to MAP) of an instrument approach. The
GNS 430 will not allow the modifications.
Invalid waypoint ident —An attempt was made to create a user
waypoint with an invalid name. The GNS 430 will not allow spaces
between characters in the waypoint name.
MAIN processor requires service —The GNS 430 has detected a
failure in the main system processor. The GNS 430 is not usable and
should be taken to your GARMIN dealer for service.
Memory battery low —The internal battery that sustains user
memory is low and should be replaced by a GARMIN dealer as soon
as possible. Failure to do so may result in loss of stored data, including
flight plans, user waypoints, unit settings and satellite data.
Near airspace -- less than 2 nm —Your GPS-calculated position is
within 2 nautical miles of a special use airspace boundary, but you are not
projected to enter the airspace. This message is automatically disabled
within 30 nautical miles of an arrival airport, when an approach is loaded.
Need altitude - display position page —The GPS receiver needs
altitude input in order to start and/or continue 2D navigation. Select the
position page and verify the altitude reading. If the altitude is in error by
more than 500 feet, enter the current altitude as accurately as possible.
An inaccurate altitude will directly translate into inaccurate position
information.
No altitude input is being received —No altitude data is being
received from RS-232 (Serializer: Icarus, Rosetta or Shadin) or grey code
inputs. If the problem persists, contact your GARMIN dealer and check
the installation and installation settings. When this message occurs, no
pilot action is required if enough satellites are available for a 3D posi-
tion fix (provided no RAIM warnings are present). However, if only a 2D
position fix is possible, the pilot should maintain the GPS altitude within
1,000 feet of pressure altitude—by entering the altitude on the position
page.
