    1.1 What is Radar? The term “RADAR” is an acronym meaning RAdio Detection And Ranging. Although the basic principles of radar were developed dur- ing World War II, echoes as an aid to naviga- tion is not a new development. 1.2 How Ships Determined Position Before Radar Before the invention of radar, when running in...

  • Page 18: Selecting The Range

    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.

  • Page 19: Adjusting The A/C Rain Control (Reducing Rain Clutter)

    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. If the control is set too low, targets will be hid- den in the clutter, while if it is set too high, both sea clutter and targets will disappear from the display.

  • Page 20: Erasing The Heading Line, North Mark

    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 tem- porarily erase the heading line and north mark by pressing and holding down the [GAIN (HM OFF)] control.

  • Page 21: Measuring The Bearing
