WEATHER DISPLAY CALIBRATION
The radar display has been calibrated to show five levels of target inten-
sity: Black (level 0), Green (level 1), Yellow (level 2), Red (level 3), and
Magenta (level 4). The meaning of these levels is shown in the following
chart as to their approximate relationship to the Video Integration
Processor (VIP) intensity levels used by the National Weather Service.
These levels are valid only when; (1) the Wx and WxA mode are
selected; (2) the displayed returns are within the STC range of the radar
(approximately 40 miles); (3) the returns are beam filling; (4) there are no
intervening radar returns.
