    SAFETY INSTRUCTIONS Before turning on the radar, make sure that there is no one near the scanner unit. Serious injury or even death may result if a rotating antenna strikes someone standing nearby. Radio Frequency Radiation Hazard The radar antenna emits electromagnetic radio frequency (RF) energy which can be harmful, particularly to your eyes.
  • Page 4 WARNING ELECTRICAL SHOCK HAZARD Do not open the equipment. Only qualified personnel should work inside the equipment. Turn off the radar power switch before servicing the scanner unit. Post a warn- ing sign near the switch indicating it should not be turned on while the scanner unit is being serviced.

    INTRODUCTION A Word to the Owner of FURUNO Radar Thank you for purchasing this FURUNO radar and/or ARPA. We are confident you will dis- cover why FURUNO has become synonymous with quality and reliability. Dedicated in the design and manufacture of marine electronics equipment for 50 years, FURUNO Electric Company has gained an unrivaled reputation as a world leader in the in- dustry.

  • Page 8: About This Manual

    "This device was designed and manufactured to comply with the International Mari- time Organization (IMO) Performance Standards for Automatic Radar Plotting Aids (ARPA)." WARNING If your ship is 10,000 or more gross tons and scheduled to operate in the navigable waters of the United States, make sure the above label is attached on the ARPA.

  • Page 9: Features

    Features The new FR-2805 series of radar and the FAR-2805 series of ARPAs are the results of com- bination of the FURUNO's many years of experience in the marine field and the advanced computer technology. The FR-2805 series and FAR-2805 series are designed to fully meet the exacting rules of the International Maritime Organization (IMO) for installations on all classes of vessels.

    1.7 Degaussing the CRT Screen Each time the radar is turned on, the de- gaussing circuit automatically demagne- tizes the CRT screen to eliminate color contamination caused by earth's magne- tism or magnetized ship structure. The screen is also degaussed automati- cally when own ship has made a signifi- cant course change.

    Performance of auto-acquisition is en- hanced by controlling the limit lines (sup- pression line) in the former series of FURUNO ARPAs. In this new series of ARPAs, the automatic acquisition rings are used instead of the limit lines. Auto acquisition rings work as suppres- sion lines when viewed from the opposite direction.

    When the range to the SART is reduced to about 1 nm, the radar display may show also the 12 responses generated during the fast sweeps. These additional dot re- sponses, which also are equally spaced by 0.64 nm, will be interspersed with the original line of 12 dots.

    A.1 Performance Monitor For X-band radars, the FURUNO PM-30 satisfies the reguirement covering 9410 50 MHz. For S-band radars, the PM-50 is available covering 3050 30 MHz. The performance monitor is an indepen- dent unit, namely, it is not interconnected with any unit of the radar system except for the 100 VAC power cable.
