To select the bird mode setting, open the [Layers] menu, tap [Bird Mode], then se-
lect [Calm], [Moderate], or [Rough].
[Calm]: Suitable in calm conditions where sea clutter is weak. Applies low sea clutter
reduction to show weak bird echoes. When sea clutter is strong, bird echoes may be
hidden inside the sea clutter.
[Moderate]: Suitable where sea clutter is moderate. Applies medium sea clutter re-
duction.
[Rough]: Suitable in rough weather conditions where sea clutter is strong. Applies
high sea clutter reduction. Weak bird echoes may be suppressed in this setting.
To turn off the bird mode, select [Off]. When the bird mode is active, the bird mode

Usage precautions
• The Bird mode is available with the radar sensors DRS6A X-Class, DRS12A X-
Class, DRS25A X-Class. The radar sensor DRS4DL/DRS4DL+ does not support
the Bird mode.
• Do not use the Bird mode in rough weather.
• Do not use the Bird mode during a voyage. The Bird mode settings are not suitable
in a voyage.
• ARPA performance may be reduced when the Bird mode is active.
• Radar Adjust (Gain, Sea, Rain) and Auto Sea Mode cannot be adjusted when the
Bird mode is active.
• Schools of fish that attract birds tend to dive suddenly, which may result in unstable
or disappearing echoes.
6.23 Target Analyzer
The target analyzer analyzes echoes and displays targets in different colors to help
you distinguish targets that are moving and approaching own ship. Use this function
to distinguish targets from heavy rain or snow.
Note 1: Requires one of the following radar sensors and GPS position data.
Note 2: [Radar Adjust] (Gain, Sea, Rain) and [Auto Sea Mode] cannot be adjusted
when the Target Analyzer is active.
Note 3: The Target Analyzer works only against moving targets. Stationary targets,
such as a buoy, are not identified as an approaching target.
