3.5 Interference rejection (IR)

This feature is used to reject radar interference from other radars.

Radar transmissions in the same frequency band can cause interference noise on the display

depending on its transmitted power. This noise pattern appearance varies case by case, but is usually

spiral in shape or like the spokes of a wheel in shape.

This equipment can reduce this phenomenon.

[IR] can be changed directly at the upper light of the screen.

[IR] is also effective to reduce second time echo phenomenon.

Move the cursor to set value window of [IR] at the upper right part of the screen.
Press [ENT] key repeatedly until desired value appears.

• The setting value can be selected from “OFF, 1, 2, 3, 4, 5” and the larger value applies stronger

interference rejection effect.

• Note: Too much removal effect may also remove small targets. Pay attention to that.
