2.5 Interfacing with the Radar Display 33
TIP: Adjust the sea clutter reduction to a level such that some clutter remains visible on
the radar display. If all clutter is removed, smaller targets may be missed and become a
threat to your boat.
2.4.3 Adjusting Rain Clutter Reduction
Rain Clutter are echoes reflected off rain, snow, and hail in the same manner as normal
targets. The rain clutter setting reduces the appearance of clutter caused by nearby rain,
but it can also reduce or eliminate the appearance of nearby targets. Reducing the radar
range can also minimize rain clutter.
• Rotate the [RAIN] knob to adjust the rain clutter reduction and reduce echoes caused
by rain.
• You can also adjust rain clutter by pressing [MENU] > Echo Tuning > Rain Clutter .
TIP: Adjust the rain clutter reduction to a level such that other targets are clearly visible
on the radar display. Some clutter caused by rain may still be visible.
2.4.4 Reducing Crosstalk Clutter
Interference caused by nearby radar sources in the same frequency band as your radar,
and may appear as clutter on the radar display. Turn on crosstalk rejection to reduce
cross talk clutter.
• Press [MENU] > Echo Tuning > Crosstalk Rejection to toggle crosstalk rejection on/off.
