Radar
Set the Radar dialog box according to the radar connected.
29.Click the Radar Source select pull-down menu, and choose the radar type connected, DRS
RADOME, DRS OPEN or FAR-2xx7.
For "FAR-2xx7", steps 30 through 31 shown below cannot be done. Set these items on the
FAR-2xx7 radar.
30.Click the Antenna Height pull-down menu, and choose the height of the antenna above the
waterline, among Under 10ft, 10ft-30ft or Over 30ft.
31.Do the heading adjustment as follows.
You have mounted the radar sensor facing straight ahead in the direction of the bow. There-
fore, a small but conspicuous target dead ahead visually should appear on the heading line
(zero degrees).
In practice, you will probably observe some small errors on the display because of the diffi-
culty in achieving accurate initial positioning of the radar sensor. The following adjustment will
compensate for this error.
a) Set ship's heading toward a suitable target (for example, ship or buoy).
b) Click the Range pull-down menu, and choose a range between 0.125 and 0.25 nautical
miles.
c) Click the [Push TX] button to transmit.
The radar picture appears on the right-half of the Radar dialog box.
d) If necessary, adjust the gain, sea clutter and rain clutter using slider bars.
Place the cursor on the slider bar, and press the cursor pad while pressing the left-click but-
ton.
e) Click the [-] [+] buttons for Heading Adjust to bisect the target with the heading line.
f) As a final test, move the boat towards a small buoy and confirm that the buoy shows up
dead ahead on the radar when it is visually dead ahead.
