Wiper

The wiper feature automatically reduces the brilliance of unwanted weak signals
(noise, sea clutter, rain clutter, etc.) and unnecessary signals, like radar interference,
to clear the picture of unnecessary echoes. The result of wiper depends on the wiper
setting used and whether echo averaging is turned on or off, as described below.
Echo Average Off
Echo Average On (1, 2, Auto)
Processing content A: The brilliance of unnecessary weak echoes, like noise and
radar interference, is reduced to clear the picture. The difference between wiper 1 and
2 is that brilliance is lowered more slowly in 1.
Processing content B: Echo averaging is automatically turned on from off when the
wiper feature is turned on. You can see how the picture changes with the echo aver-
aging turned off and turned on.
To activate the wiper feature, do the following:
1. Press the MENU/ESC key to open the menu.
2. Use the Cursorpad ( or ) to select [Echo] and press the ENTER key.
3. Use the Cursorpad ( or ) to select [Wiper] and press the ENTER key.
