Right-hand Keys and Knobs
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 Direct-to Key provides access to the direct-to
function, which allows the pilot to enter a destination
waypoint and establishes a direct course to the selected
destination (Section 4).
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 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.
