Copying Map Settings into the Scratchpad
It may be desired to copy settings that have been previously stored

Automatic Decluttering
Occasionally, the SN3500 map display may become too cluttered to
read, such as by turning on several categories of map items. The
SN3500 will automatically remove items from the display if the total
number of items is too great to display. When this occurs, it is
indicated by an icon color change from cyan to yellow on the map
status bar as shown following:
Normally the SN3500 will allow up to approximately 50 icons before
this action occurs, but this number may be smaller if complex
airspace is displayed simultaneously. When automatic decluttering
occurs, it occurs first to objects closest to the aircraft. When the
display is zoomed-in, these objects will reappear and the associated
status bar icon will turn back to cyan.
Maximum Range of Internal Map Data
During normal operation, the SN3500 only displays items from its
internal database that are within 200nm of the current aircraft
position (400nm for long range VORs and NDBs), even when the
selected map range is larger.
Clearing the Map Display
To quickly turn off the map display, press [CLR]. The map display
will be removed. Pressing [CLR] again will return to the most
recently displayed map memory location.
