FOREWORD

Foreword

Thank you for purchasing the FURUNO DS-80 Doppler Speed Log. We are confident you will discover why FURUNO has become synonymous with quality and reliability.

Dedicated in the design and manufacture of marine electronics equipment for half a century, FURUNO Electric Company has gained an unrivaled reputation as a world leader in the industry. This is the result of our technical excellence as well as our worldwide distribution and service network.

Please carefully read and follow the safety information and operating and maintenance instructions set forth in this manual before attempting to operate the equipment and conduct any maintenance. Your Doppler speed log will perform to the utmost of its ability only if it is operated and maintained in accordance with the correct procedures.

This equipment is designed, produced and documented by FURUNO Electric Co., Ltd., complying with ISO 9001 standards as certified by the Lloyd’s Register of Quality Assurance System.

Features

The FURUNO DS-80 displays ship’s speed relative to water, using the Doppler principle; ship’s speed is measured by detecting the Doppler shift frequency from the signal returned from the watermass.

The output is interfaced with ARPA, AIS, and other shipborne equipment in IEC 61162-1 format.

The main features of the DS-80 are

•Simple operation. In most cases all that is required to display ship’s speed is to turn on the equipment.

•Pair-beam system effectively reduces error caused by pitching. The transducer assembly symmetrically emits two sonic beams, one fore and the other aft. By averaging the Doppler shift in both directions accurate speed data is available under rough sea conditions.

•Speed and distance information on the adjustable-contrast LCD display.

•Analog display, digital Indicator and digital distance indicator display optionally available.

•Conforms to the following standards: IMO A.824(19), as amended by MSC.97(72),

IMO A.694(17), IEC 61023, IEC 60945 (3rd edition), IEC 61162-1 (2nd edition)..
