GENERAL RADAR OPERATION

Interference Rejection (IR)

Interference by other radars is rejected.
Attention
When viewing a radar beacon or SART signal, select

processing suppresses the video.
Procedures 1 Put the cursor on interference rejection (IR) mode switching
( ② lower left of the display on page 2-18) and press the [ENT] key.

Rejection levels of the interference rejection
When a high interference rejection level is selected, the radar's ability of detecting
small targets such as buoys and small boats lowers.

IR Off ⇒ IR Low ⇒ IR Middle ⇒ IR High ⇒
IR Off : Interference rejection off
IR Low : Interference rejection level - low
IR Middle : Interference rejection level - middle
