The
nearest
(
NRST)
key (400W/420W
only) displays the nearest airports page.
Then, turning the
small right
knob steps
through the NRST pages.
The
CDI
key (430W only) is used to toggle
which navigation source (GPS or VLOC) pro-
vides output to an external HSI or CDI.
The
OBS
key is used to select manual or
automatic sequencing of waypoints. Pressing
the
OBS

retain the current “active to” waypoint as
your navigation reference even after pass-
ing the waypoint (i.e., prevents sequencing
to the next waypoint). Pressing the
OBS
key again will return to normal operation,
with automatic sequencing of waypoints.
Whenever OBS mode is selected, you may set
the desired course to/from a waypoint using
the OBS Page, or an external OBS selector on
your HSI or CDI.
The
message
key (
MSG
) is used to view
system messages and important warnings and
requirements. See Sections 11 and 9 for more
information on messages and unit settings.
The
flight plan
key (
FPL
) allows you to
create, edit, activate and invert flight plans,
as well as access approaches, departures and
arrivals. A closest point to flight plan feature
is also available from the flight plan key. See
Section 4 for more information on flight
plans.

The
procedures
key (
PROC
) allows you to
select and remove approaches, departures
and arrivals from your flight plan. When
using a flight plan, available procedures for
your departure and/or arrival airport are
offered automatically. Otherwise, you may
select the desired airport, then the desired
procedure.
Whenever the 400W-series unit is dis-
playing a list of information that is too
long for the display screen, a scroll bar
will appear along the right-hand side
of the display. The scroll bar graphically
indicates the number of additional items
available within the selected category.
Simply press the small right knob to
activate the cursor and turn the large
right knob to scroll through the list.
