The small left knob (COM/VLOC) is used to tune the kilohertz (kHz) value (to the right of the decimal
point) of the standby frequency for the communications transceiver (COM) or the VLOC receiver,
whichever is currently selected by the tuning cursor. Press this knob momentarily to toggle the
tuning cursor between the COM and VLOC frequency fields.
The COM flip-flop key is used to swap the active and standby COM frequencies. Press and hold
to select emergency channel (121.500 MHz).
RIGHT-HAND KEYS AND KNOBS
The range key (RNG) allows you to select the desired map scale. Use the up arrow side of the key
to zoom out to a larger area, or the down arrow side to zoom in to a smaller area.
The direct-to key provides access to the direct-to function, which allows you to enter a destination
waypoint and establishes a direct course to the selected destination.
The MENU key displays a context-sensitive list of options. This options list allows you to access
additional features or make settings changes which relate to the currently displayed page.
The clear key (CLR) is used to erase information or cancel an entry. Press and hold this key to
immediately display the Default Navigation Page, regardless of which page is currently displayed.
The enter key (ENT) 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 you to move the cursor about the
page.
The small right knob (CRSR) 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 you
to enter data and/or make a selection from a list of options.
BOTTOM ROW KEYS
The nearest (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 will retain the current „active to“ waypoint as your navigation
reference even after passing 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.
