4 BASIC OPERATION

The following are typical basic operation examples, which may hinder radar reception (sea clutter, precipitation interference and echoes from other radar).

■ RAIN function

This function eliminates reflection echoes from rain, snow, fog etc.

• Rotate the control fully counterclockwise to deactivate the control function. The RAIN indicator () disappears.

• NOTE: DO NOT reduce the reflection echoes too much, otherwise you may miss weaker targets.

Small echos Adjust RAIN control

■ SEA function

This function serves to eliminate echoes from waves at close range. Reduce the receiver gain for close objects within a radius of 8 miles to eliminate sea clutter.

• Rotate the control fully clockwise to activate the automatic control function. SEA indicator ()appears in the upper left

			of the screen.
			WARNING: The [SEA]/[	] control re-
			duces the receiver sensitivity of objects within 8
Echos from	sea waves	Adjust SEA control	miles. Therefore, caution and careful adjustment are
			necessary when using the [SEA]/[	] control.
			Small objects may not be displayed on the screen
			when strong echoes from the rain or the island within
			1 NM while automatic SEA function is activating.
