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. •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.
BASIC OPERATION 4 ■ Basic operation q Turn the power ON. w Push [TX] after the countdown disappears from the screen. w • See “Turning power ON/OFF” on page at left. e Push [+] or [–] key one or more times to select the display range. r • The screen range readout shows the maximum range of the screen. r Push [ADJ] then adjust the [GAIN]* to be on the threshold of max. screen range. • Increases the gain. • Increased gain may increase screen noise. t Select [SEA]*, then set the [SEA]* to minimum.
4 BASIC OPERATION The followings 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. • Adjust the lowest level to deactivate the control function. • 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 [ADJ] to call up “ADJUST” menu. w Push [ ]/[ ] until the “IR” section becomes highlighted. e Push [ ]/[ ] to select IR function ON or OFF. With IR function on Radar interference ■ ECHO STRETCH function The blips can be magnified electronically for easier viewing of small targets. (p.
4 BASIC OPERATION ■ TRAILS function •Setting the trail interval time q Push [MENU] to call up the FUNCTION menu. The trails function memorizes echoes continuously or at constant intervals. This is useful for watching other ships’ tracks, approx. relative speed, etc. • Push [ ] several times until the “TRAIL TIME” section becomes highlighted. w Push [ ]/[ ] to select trail interval time. • 15 sec., 30 sec., 1 min., 3 min., 6 min., 15 min., 30 min. and ∞ (continuous) are available.
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 kilometres/hour (KM/h) are automatically selected in the normal screen (p. 00) by selecting nautical miles (NM) or kilometres (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. The distance unit, nautical miles (NM) or kilometres (KM) is selected in the “INIT.SETTING” menu (p. 9). 3 2530˚T NM DESCRIPTION RING Displays fixed rings. Suitable for rough estimations from your own ship to any target. VRM1 Displays a variable range marker.Suitable for accurate measurements from your own ship to a target.
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. • Using the EBL and VRM–1 3 • Using the variable range marker q Push [ ]/[ ]/[ ]/[ ] several times to move the cross line cursor on the target. w Push [EBL1 (VRM1)] to display the EBL1 and VRM1. 2530˚T NM (1) • The EBL1 and VRM1 readouts indicate the target bearing and distance.
5 DISTANCE AND DIRECTION MEASUREMENTS ■ Advanced measurements Using both Electronic Bearing Lines (EBL) and both Variable Range Markers (VRM), the following advanced measurements can be made: • Measuring the distance and direction between 2 targets 3 2530˚T NM (1) EBL1 VRM2 VRM1 EBL2 • The intersection of the EBL1 and VRM1 becomes the center of the EBL2 and VRM2. y The VRM2 readout shows the distance between the two targets. The EBL2 readout shows the direction from one target to the other.
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 LCD OFF until an alarm is given, to conserve power. ■ Alarm zone setting q Push [+]/[–] to select the desired range.
7 EPA (Electronic Plotting Aid) ■ EPA (Electronic Plotting Aid) The EPA (Electronic Plotting Aid) for manual plotting is interfaced for small ships fitted with a gyrocompass, speed and distance measuring equipment. EPA (Electronic Plotting Aid), will in order to improve the standard of collision avoidance at sea, reduce the workload of the crew by enabling them to obtain information about plotted targets, as well as they could by manually plotting a single target themselves. • Max.

BASIC RADAR THEORY 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. 8 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. When tall and massive targets such as a large island are located at close range is also shadowed without producing any echoes.This phenomenon is called blind sector.
