IR Off (Interference Rejection Off) because IR
processing suppresses the video.
Attention
Procedures 1 Put the cursor on interference rejection (IR) mode switching IR
( â‘¡ lower left of the display on page 2-18) and press the [ENT] key.
The interference rejection modes are switched.
IR Off ⇒ IR Low ⇒ IR Middle ⇒ IR High ⇒ IR Off
Rejection levels of the interference rejection
IR Off : Interference rejection off
IR Low : Interference rejection level - low
IR Middle : Interference rejection level - middle
IR High : Interference rejection level - high
When a high interference rejection level is selected, the radar’s ability of detecting
small targets such as buoys and small boats lowers.
In general, IR Low should be selected.
