insertion and removal.
Right-hand Keys and Knobs
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.
Pressing the
Direct-to
Key allows the pilot to enter a
destination waypoint and establishes a direct course to the
selected destination (Section 3).
The
RNG
Key allows the pilot to select the desired
map range. Use the up arrow to zoom out to a larger area,
or the down arrow to zoom in to a smaller area.
The
MENU
Key displays a context-sensitive list of
options. This options list allows the pilot to access
additional features or make settings changes which relate
to the currently displayed page.
The
ENT
Key is used to approve an operation or
complete data entry. It is also used to confirm information
during power on.
The large
right
knob (CRSR) is used to select 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 (CRSR) is used to select 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.
`
NOTE: Data is entered using the large and
small
right
knobs (Figure 1-2). Experiment with
them to become efficient at entering data. This
will greatly reduce the amount of time spent
operating the GPS 400 in flight.
