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).
In practice, you will probably observe some small bearing error on the display because
of the difficulty in achieving accurate initial positioning of the antenna unit. The follow-
ing adjustment will compensate for the error.
1. Set your radar with 0.125 and 0.25 nm range and the head up mode.
You can select a range by using the pinch action. The range appears at the bottom
right of the screen. Range may also be selected using the slide bar displayed on
[ARPA Advanced Set-
tings]
For service technician only. Do not change these settings.
This item is available when [TX/STBY] is [ON].
Not available (grayed out) with the radar sensor DRS4DL, DRS4DL+, or
FAR-2xx8, FAR-2xx7, FAR-15x8 series radar antenna.
[TX Channel] Select [1], [2] or [3], the channel where the
interference is smallest. See the operator’s
manual for details. Available with the radar
sensor DRS2D-NXT, DRS4D-NXT.

[Target Analyzer Mode] You can emphasize rain clutter or target
echoes when the target analyzer is active.

[Rain], [Target]
[Auto acquire by Dop-
pler]
When selecting [ON], approaching targets
(ships, rain clutter, etc.) within 3 NM from
own ship are automatically acquired by the
Doppler calculated from the radar echo. See
the operator’s manual for details. Available
with the radar sensor DRS2D-NXT, DRS4D-
NXT, DRS6A-NXT, DRS12A-NXT,
DRS25A-NXT.
