Operation
If there is no valid GPS or FMS position fix data available, the words NO
EXTERNAL POSITION DATA will be shown across the center of the
display in a box. If the fix is lost at any time during normal operation of
the unit, the same NO EXTERNAL POSITION DATA box will be overlaid
on the map.
NOTE: Do not use the map for navigation while this message is dis-
played.
The map will be shown in either North Up orientation or Track Up orien-
tation depending upon the setting selected in the Map Setup section and
reflected by the North Pointer in the upper left of the display. The DIS
field in the upper left of the display indicates distance to waypoint.
The displayed data is updated every second. Press
the RNG
Δ
(range up) or RNG
∇
(range down) key at
any time to zoom the map in and out to whichever
one of the twelve pre-set scales desired. The avail-
able range settings are 1, 2.5, 5, 10, 20, 40, 80, 160,
320, 500, 1000 and 2000nm. The levels of detail
appearing at each zoom level can be changed in the
Map Setup section.
When active, Auto Zoom
automatically adjusts the
range setting up or down as
needed to keep the flight
plan active waypoint within
the viewable area of the Map
display. The flight plan must
be overlayed on the Map dis-
play for Auto Zoom to be
enabled.
Auto Zoom is enabled in
either of the following ways:
1. Pressing RNG
Δ
while on
the 2000nm range setting.
2. Pressing and holding either RNG Key for 2 seconds or more. While
the RNG Key continues to be pressed, a hold-to-help box willl be dis-
played as shown in Figure 4.
While Auto Zoom is enabled, AUTO is displayed in small black text to
the right of the current range setting (see Figure 4).
Auto zoom can be canceled in one of the following ways:
1. Pressing either RNG Key.
2. The flight plan becomes invalid.
