Press the
ADJUST RADAR
key to display the first of three
pages of radar adjustments. Most of these adjustments
correspond to conventional radar adjustments and are used in
the same way.
Using the keys
The keys on each page have two or more parts: the upper part
shows the function (such as
RAIN CLUTTER
) and the lower
part shows the status (such as
MANUAL
). Some keys also have
a middle part that shows a numerical value (such as
30
).
To use a key:
1. Press the key once to select the function (a small arrow
appears next to the function).
2. Press the key a second time to select the status (a small
arrow appears next to the status).
3. Change the status by pressing the key repeatedly or by
using the
CONTROL PAD
up and down arrow keys.
4. If a numerical value appears on the key (either in the mid-

•
Either press the
CONTROL PAD
up and down arrow
keys
•
Or use the number keys on the
KEYPAD
to enter the
quantity you want
