PUSH: Increases the map range, in nautical miles, shown
on the main display area. Range is always measured from
the white airplane indicator to outside of the compass tick
marks.
Pushing the [ ] button increases the map range from 1
nautical mile to 1000 nautical miles. The currently selected
map range is shown at the top of the display. When the
top of the map range is reached, further pushes of [ ]
have no effect.
HOLD: If a flight plan or a direct-to waypoint is active on
the LNAV receiver, the map range will auto-scale until
reaching a setting at which the entire flight plan is visible.

If a WX-500 Stormscope
®
lightning detection sensor is
configured with the SN3308, a softkey is provided to
access Stormscope functions. Softkeys are labelled with
the following selections: OFF, CELL, STRK, CLEAR and
SETUP MENU. Selecting SETUP MENU displays a sub-
menu which provides access to the SELF TEST and DEMO
functions.
If a WX-500 is not present in the system, this button
sequence has no effect. The message “WX NOT
INSTALLED” will be displayed at the top of the screen.
