2.14 The Window Display
The window display appears at the bottom
left (or right) 1/4 of the display. Two types of
window displays are available: zoom and
wide. Zoom doubles the size of the area
selected by the operator, and wide (range-
up) compresses and displays the entire
radar picture from the next higher range.
Note 1: The zoom display does not
function on the 0.125 and 0.25 nm
ranges.
Note 2: The wide display does not function
on the 48 nm range.
