How to align the antenna heading
You have mounted the antenna unit facing straight ahead in the direction of the bow.
Therefore, a small but conspicuous target dead ahead visually should appear on the
heading line (zero degrees).
You may observe a minor bearing error on the display. This is due to the difficulty in
orienting the radar accurately. The following adjustment will compensate for the error.
Select the antenna rotation speed.
See "How to align the antenna heading" on page 19.
If main bang appears at the screen center, slide the circle
icon so that the main bang disappears, while watching the
radar echo at the left-hand side of the display.
Up to two sectors may be selected for blanking (no trans-
mission). Select [ON] to enable this feature. Set the start
and end angles (0° to 359°).
Referring to the figure on the right, enter the ra-
dar antenna positioning bow-stern (Longitudi-
nal) and port-starboard (Lateral) position from
the origin.
Selects the height of the antenna above the waterline.
Selects the length of the antenna. RezBoost function re-
flects the selection of this menu item.
Display various information regarding the connected ra-
dar.
Select [1], [2] or [3], the channel where the interference is
smallest.
You can emphasize rain clutter or target echoes when the
target analyzer is active. Select [Rain] or [Target] as ap-
propriate.
When selecting [ON], approaching targets within 3 NM
from own ship are automatically acquired by the Doppler
calculated from the radar echo.
Resets the radar selected at [Radar Source] to factory de-
fault.
Resets [Radar] menu settings to default.
