1. PRINCIPLE OF OPERATION 1.1 What is Radar? The term “RADAR” is an acronym meaning RAdio Detection And Ranging. Although the basic principles of radar were developed during World War II, echoes as an aid to navigation is not a new development. 1.2 How Ships Determined Position Before Radar Before the invention of radar, when running in fog near a rugged shoreline, ships would sound a short blast on their whistles, fire a shot, or strike a bell.
Heading line Targets A D A B D B C C Own ship in center Own ship (radar) (A) Bird's eye view of situation (B) Radar picture of (A) Figure 1-1 How radar works 2 Range and bearing of a target, relative to own ship, are readable on the PPI.
2. BASIC OPERATION 2.1 Control Description Omnipad Shifts cursor, VRM and EBL; select items and options on menu. Brief press: Displays the data of target selected with the cursor. Long press: Terminates plotting of the target selected with the cursor. Opens/closes menus. CANCEL ACQ ENTER Selects EBL1/EBL2/VRM1/VRM2. MENU GUARD SELECT Control: Adjusts sensitivity. Switch: Temporarily erases heading line (and north mark if displayed). EBL/VRM CONTROL GAIN TLL Control: Reduces sea clutter.

2.3 Turning the Radar On/Off 2.5 Stand-by Press the [POWER] key to turn the radar on or off. The control panel lights and a timer displays the time remaining for warm up of the magnetron (the device which produces radar pulses), counting down from 1:30 to 0:01. When you won’t be using the radar for an extended period, but you want to keep it in a state of readiness, place it in stand-by by pressing the [STBY TX] key.
Note 1: Availability of a particular display item depends on incoming data. Note 2: When Range to Waypoint reaches 0.1 nm, the WPT mark jumps to dead ahead even though a difference may exist between heading and BRG to WPT. Note 3: When cross track error exceeds 1 nm on either side, the XTE mark starts blinking. 2.
Adjusting the A/C SEA control The proper setting of the A/C SEA should be such that the clutter is broken up into small dots, and small targets become distinguishable. 2.10 Adjusting the A/C RAIN Control (reducing rain clutter) If the control is set too low, targets will be hidden in the clutter, while if it is set too high, both sea clutter and targets will disappear from the display. In most cases adjust the control until clutter has disappeared to leeward, but a little is still visible windward.
2.11 Erasing the Heading Line, North Mark The heading line or north mark (available with gyrocompass connection) may occasionally mask a target. To view the target, you can temporarily erase the heading line and north mark by pressing and holding down the [GAIN (HM OFF)] control. Release the control to re-display the marks.

2.13 Measuring the Bearing There are two ways to measure the bearing to a target: by the cursor, and by the EBL (Electronic Bearing Line). Note: The bearing readout for the EBL and the cursor can be displayed in relative or true bearing (true bearing requires heading sensor input). For north up and course up display modes the bearing reference is always true. For details see the next chapter. By cursor Operate the omnipad to bisect the target with the cursor intersection.
