5 DISTANCE AND DIRECTION MEASUREMENTS

■Distance measurement

TYPE	DESCRIPTION
	Displays fixed rings.
RING	Suitable for rough estimations from your
	own ship to any target.
	Displays a variable range marker and ac-
	tivated by the [Ù Ú] for the range marker
VRM1	selector.
	Suitable for accurate measurements from
	your own ship to a target.
	Normally functions the same as VRM1.
	When the VRM1 and EBL1 selects a tar-
VRM2	get, the center of VRM2 appears at the
	intersection point.
	Suitable for accurate measurements from
	target to target.

Two measurement procedures are available with this radar. Operating them separately or jointly is possible.

The distance unit, nautical miles (NM) or kilometers (KM) is selected in the FUNCTION menu (p. 6).

DUsing the variable range marker

q Push [EBL1 (VRM1)]/[ ] to display the VRM1 and EBL1; then, push [Ù Ú] to set the marker.

• The range between the ship and the target is indicated in the VRM readouts.

w Push [EBL2 (VRM2)]/[] to display the VRM2 and EBL2; then, push [Ù Ú] to set the marker.

• The range between the ship and the target is indicated in the VRM readouts.

• When the VRM1 and EBL1 are displayed, the center of VRM2 appears at the intersection point of the VRM1 and EBL1.

• The VRM2 disappears when [EBL1 (VRM1)] is pushed.

e Push [EBL1 (VRM1)]/[ ] to exit the menu display.
