4 BASIC OPERATION ■ Checking the installation Before turning the power ON, be sure all the connections are complete. The checklist at right may be helpful for necessary confirmation. CAUTION: Connect the scanner unit before turning the power ON. Otherwise the magnetron inside the scanner unit might be damaged. D Checklist q The 4 bolts securing the scanner unit must be firmly tightened. w Cabling must be securely attached to a mast or mounting material, and must not interfere with the rigging.

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.
BASIC OPERATION 4 ■ IR function Radar interference may appear when another ship’s radar is operating on the same frequency band in close proximity. The IR function can eliminate this type of interference. (p. 6) q Push [MENU]/[ ] to call up VIDEO menu. w Push [Ú] until the “IR” section becomes highlighted. e Push [Ω ≈] to select IR function 1, 2 or OFF. • “IR” appears in the upper right of the screen, when the function is activated.

BASIC OPERATION 4 ■ Ship speed indication ■ Long pulse function When the ship speed data with NMEA 0183 format is applied, the radar can display the ship speed. Knots (KT) or kilometers/hour (KM/h) are automatically selected in the normal screen (p. 4) by selecting nautical miles (NM) or kilometers (KM) respectively. To magnify the blips for easier viewing of small targets, the long pulse and echo stretch (p. 11) functions are available.
5 DISTANCE AND DIRECTION MEASUREMENTS ■ Distance measurement Two measurement procedures are available with this radar. Operating them separately or jointly is possible. TYPE DESCRIPTION RING Displays fixed rings. Suitable for rough estimations from your own ship to any target. VRM1 Displays a variable range marker and activated by the [Ù Ú] for the range marker selector. Suitable for accurate measurements from your own ship to a target. VRM2 Normally functions the same as VRM1.
DISTANCE AND DIRECTION MEASUREMENTS 5 ■ Bearing and Distance measurement This radar has 2 Electronic Bearing Lines (EBL) to indicate the target direction from your ship or a target. D Using the EBL and VRM 3/4 NM CURS SOG 00km/h 3240R H UP q Push [Ù Ú Ω ≈] to move the cursor on the desired target. w Push [EBL1 (VRM1)]/[ ] to display the EBL1 and VRM1.

IR ES VRM2 • Push [Ω ≈] to rotate the electronic bearing line.
ALARM FUNCTION 6 The unit has an alarm function to protect your ship from collisions. If other ships or islands, etc. come into the preprogrammed alarm zone, the function alerts you with an alarm. You can set the desired range and bearing for an alarm zone. While the alarm function is activated, the power save function turns the CRT OFF until an alarm is given, to conserve power. ■ Alarm zone setting D Setting and using the alarm function (0.
7 ATA (Automatic Tracking Aid) ■ ATA (Automatic Tracking Aid) By tracking automatically the target chosen by the cursor key, the closest point of approach (CPA) and the time to closest point of approach (TCPA) limit of a own ship and a target are calculated. ATA is the function to tell about to alarm sound, when both CPA and TCPA becomes below a setting value (the approach watch area). The range of the target which can be registered is taken as a target with a highest luminosity level of 0.2–16 miles.
ATA (Automatic Tracking Aid) 7 ■ ATA operation Select the target which you want to track on the display. NEW q Push [Ù Ú Ω ≈] to move the “+” cursor on the desired target. w Push [TARGET]/[ ] for 1 sec. to select the target for tracking.

BASIC RADAR THEORY 8 Radar uses a form of electromagnetic radiation, which like light, can be reflected. Because of this property, some objects may cause false echoes on the screen where in fact no targets actually exist. These echoes may appear if a large vessel, bridge, or tank is in proximity. Operators should be familiar with the effects of these phenomena. In some cases, echoes can be reduced. ■ Side-lobe echoes Radiation can escape on each side of the beam inside the lobes.
8 BASIC RADAR THEORY ■ Multiple echoes Multiple echoes may appear when a short-range and strong echo is received from a ship, bridge, or breakwater. Multiple echoes will appear beyond the target’s true echo point on the same bearing of a large target. They can be reduced with proper adjustment of the [SEA]/[ ] control. See p. 10 for the [SEA]/[ ] control. False echoes True echo Own ship Another ship ■ Minimum range Detection at short range is very important.
BASIC RADAR THEORY 8 ■ Blind and Shadow sectors Blind or Shadow sectors may exist because of obstructions such as masts, derricks or stacks. An obstruction may throw either a complete or partial shadow as shown in the diagram below. If a target is in a shadow sector, target echoes may not appear on the screen. Shadow sector When tall and massive targets such as a large island are located at close range also shadowed without producing any echoes. This phenomenon is called blind sector.
