3.4.8    Reject Radar Interference [IR] 
 
Use this function to eliminate interference waves from other radars. 
 
 
 
 
 
 
 
 
 
 
 
 
 
  Procedure    1  Press [RADAR MENU] key twice. 
 
Radar Menu will appear. 
 
2  Press [1] key. 
 
The IR Menu will appear. 
 
3  Select the level number to be set, 
pressing the numeric keys [1] to [4]. 
 
The selected level will be set. 
 
Rejection levels of the interference rejector 
IR OFF:    Interference rejector off 
IR LOW:  Interference rejection level - low 
IR MEDIUM:  Interference rejection level - 
moderate 
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. 
 
 
 
 
*  Software button  ձ  located at the bottom left corner of the radar display described in Section 2.3.2 is also 
available to switch IR settings. 
 
 
 
z  When viewing a radar beacon or SART signal, select 
IR OFF (Interference Rejector OFF) because IR 
processing suppresses the video.
