Bottom Row Keys - Garmin GPS 400 Quick Reference

The CLR Key is used to erase information, remove
map detail, or to cancel an entry. Press and hold the CLR
key to immediately display the Default NAV Page.
The ENT Key is used to approve an operation or
complete data entry. It is also used to confirm information,
such as during power on.
The large right knob is used to select between the
various page groups: NAV, WPT, AUX, or NRST. With
the on-screen cursor enabled, the large right knob allows
the pilot to move the cursor about the page. The large
right knob is also used to move the target pointer right
(turn clockwise) or left (counterclockwise) when the map
panning function is active.
The small right knob is used to select between the
various pages within one of the groups listed above. Press
this knob momentarily to display the on-screen cursor.
The cursor allows the pilot to enter data and/or make a
selection from a list of options. When entering data, the
small knob is used to select the desired letter or number
and the large knob is used to move to the next character
space. The small right knob is also used to move the target
pointer up (turn clockwise) or down (counterclockwise)
when the map panning function is active.

The NRST Key displays the Nearest Airports Page. Then,
turning the small right knob steps through the NRST pages.
The OBS Key is used to select manual or automatic
sequencing of waypoints. Pressing the OBS Key selects
OBS mode, which retains the current 'active to' waypoint
as the navigation reference even after passing the waypoint
(i.e., prevents sequencing to the next waypoint). Pressing
the OBS Key again returns the unit to normal operation,
with automatic sequencing of waypoints. When OBS
mode is selected, the pilot may set the desired course
to/from a waypoint using the 'Select OBS Course' pop-up
window, or an external OBS selector on the HSI or CDI.
The MSG Key is used to view system messages and to
alert the pilot to important warnings and requirements.
The FPL Key allows the pilot 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 FPL Key.
The PROC Key allows the pilot to select and remove
approaches, departures, and arrivals from the flight plan.
When using a flight plan, available procedures for the
departure and/or arrival airport are offered automatically.
Otherwise, the pilot may select the desired airport, then the
desired procedure.
