Interference Rejector

The radar interference can occur when your ship is near the radar of another ship that
operates on the same frequency band with your radar. The interference shows on the
screen as many bright dots. The dots can be random or in the shape of dotted lines
that run from the center to the edge of the display. You can identify the interference
from the normal echoes, because the interference does not appear in the same loca-
tion at the next antenna rotation. When this feature is turned on, "IR 1", "IR 2" or "IR
3" appears at the lower-right corner.
1. Press the MENU key to open the menu.
2. Use the Cursorpad (S or T) to select [Echo] and press the ENTER key.
3. Use the Cursorpad (S or T) to select [Int Rejector] and press the ENTER key.
4. Use the Cursorpad (S or T) to select [Off], [1], [2] or [3] then press the ENTER
key. [3] removes the interference the most.
5. Press the MENU key to close the menu.
Note: When there is no interference, turn off the interference rejector so you do not
miss the small targets.
