Garmin GPS 155XL TSO - Manual (Page 125)

Invalid copy route - A non-empty route was selected for a copy opera-
tion. 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 way-
point 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 GPS 155XL 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 155XL has failed to receive altitude
data from the parallel input. Check the I/O set-
tings and/or the installation. If enough satellites
are available for a 3D fix, no pilot action is
required, provided no RAIM warnings are pre-
sent. 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 configuration
switches if installed, or check the CDI/HSI unit.
No DGPS position - Not enough data is available to compute a differ-
ential 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The approach is no longer active.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.
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 155XL 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.
