  • Page 5 COMPLIANCE WITH R&TTE DIRECTIVE 1999/5/EC This radar complies with the R&TTE Directive 1999/5/EC. In accordance with Article 6-3 of this directive, FURUNO intends to put this radar on the market of the following countries in EU as well other markets.
  • Page 6 SART (Search and Rescue Transponder) A Search and Rescue Transponder (SART) may be triggered by any X-Band (3 cm) radar within a range of approximately 8 n.miles. Each radar pulse received causes it to transmit a response which is swept repetitively across the complete radar frequency band. When interrogated, it first sweeps rapidly (0.4 sec) through the band before beginning a rela- tively slow sweep (7.5 sec) through the band back to the starting frequency.
  • Page 7 Summary to detect SART response 1. Use range scale of 6 or 12 nm as the spacing between the SART responses is about 0.6 nm (1125 m) to distinguish the SART. 2. Turn off the A/C AUTO function. 3. Turn off the Interference Rejector. General remarks on receiving SART Radar range scale When looking for a SART it is preferable to use either the 6 or 12 nautical mile range scale.

    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 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...

    2.3 Turning the Radar On/Off Press the [POWER] key to turn the radar on. To turn the radar off, press the [POWER] key together with the [STBY/TX] key. When the radar is turned on, 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 (2:00 to 0:01 for FR-7252).

  • 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: Selecting The Presentation Mode

    2.11 Selecting the Presentation Mode This radar provides four presentation modes: head-up, course-up, north-up and true motion. Press the [MODE] key. With heading sensor connection, the display and the display mode indication at the top left-hand corner of the display change in the sequence of HU RM (Head-up), CU RM (Course-up), NU RM (North-up) and NU TM (True Motion) when the [MODE] key is pressed.

  • Page 21: Measuring The Range

    2.14 Measuring the Range You can measure the range to a target three ways: by the range rings, by the cursor, and by the VRM (Variable Range Marker). Measuring range by range rings Count the number of rings between the center of the display and the target.

    4. FALSE ECHOES Occasionally false echoes appear on the screen at positions where there is no target. In some cases the effects can be reduced or eliminated. The operator should familiarize himself or her- self with the appearance and effects of these false echoes, so as not to confuse them with echoes from legitimate contacts.

  • Page 34: Indirect Echoes

    4.3 Indirect Echoes Indirect echoes may be returned from either a passing ship or returned from a reflecting sur- face on your own ship, for example, a stack. In both cases, the echo will return from a legiti- mate contact to the antenna by the same indi- rect path.
