How to discard this product

Discard this product according to local regulations for the disposal of industrial waste. For

disposal in the USA, see the homepage of the Electronics Industries Alliance

(http://www.eiae.org/) for the correct method of disposal.

How to discard a used battery

Some FURUNO products have a battery(ies). To see if your product has a battery(ies), see

the chapter on Maintenance. Follow the instructions below if a battery(ies) is used.

In the European Union

The crossed-out trash can symbol indicates that all types of

batteries must not be discarded in standard trash, or at a trash

site. Take the used batteries to a battery collection site

according to your national legislation and the Batteries Directive

2006/66/EU.

In the USA

The Mobius loop symbol (three chasing arrows) indicates that

Ni-Cd and lead-acid rechargeable batteries must be recycled.

Take the used batteries to a battery collection site according to

local laws.

In the other countries

There are no international standards for the battery recycle symbol. The number of symbols

can increase when the other countries make their own recycling symbols in the future.

SAFETY INSTRUCTIONS

WARNING

ELECTRICAL SHOCK HAZARD

Do not open the equipment.

Only qualified personnel

should work inside the

equipment.

Immediately turn off the power at the

switchboard if water leaks into the

equipment or an object is dropped into

the equipment.

Continued use of the equipment can cause

fire or electrical shock. Contact a FURUNO

agent for service.

Do not place liquid-filled containers on

the top of the equipment.

Fire or electrical shock can result if the

liquid spills into the equipment.

Do not disassemble or modify the

equipment.

Fire, electrical shock or serious injury can

result.

Keep the equipment away from rain

and water splash.

Fire or electrical shock can result if the

rain or water gets into the equipment.

Do not operate the equipment with wet

hands.

Electrical shock can result.

Keep heater away from equipment.

A heater can melt the equipment's power

cord, which can cause fire or electrical

shock.

Use the proper fuse.

Fuse rating is shown on the equipment.

Use of a wrong fuse can result in damage

to the equipment.

Do not use the equipment for other than

its intended purpose.

Improper use of the equipment can result

in personal injury or equipment damage.

Turn off the equipment immediately if

you feel it is abnormal.

Turn off the power from the switchboard if

the equipment is emitting strange noises

or becomes excessively hot. Contact your

dealer for advice.

The useable ambient temperature range

is 15°C

55°C.

Do not use the equipment out of the

above temperature range.

Do not place objects around the

equipment.

Overheating may result.

Do not power the equipment when the

transducer is in air.

The transducer may become damaged.

Handle all units carefully.

Damage can lead to corrosion.

Do not use chemical cleaners such as

alcohol, acetone and benzine to clean

the equipment.

Chemical cleaners can remove paint and

markings. Use only a soft, dry cloth. For

stubborn dirt, use a soft cloth moistened

with water-diluted mild detergent.

When dry docked remove marine life

from the transducer.

Remove marine life to maintain good

sensitivity.

Do not paint the transducer face.

Further, handle the transducer with

care.

Paint will affect equipment performance.

WARNING LABEL

A warning label is attached to the

units shown right. Do not remove the

labels. If a label is missing or is illegible,

contacta FURUNO dealer or agent about

replacement.

WARNING

To avoid electrical shock, do not

remove cover. No user-serviceable

parts inside.

INTRODUCTION

The FURUNO DS-50 is a highly advanced, precision Doppler Speed Log incorporating FURUNO's

advanced computer technology. The DS-50 provides accurate display of speed over a wide range

from dead slow to 40 kn Speeds are detected relative to ground or water both fore/aft and athwart ship.

This feature ensures the safety and efficiency of navigation for ships operated under SOLAS 1974

and other ships.

Features

• Ground speed and water speed measurements. Three beam arrangement for highly accurate and

stable measurement.

• •Highly accurate speed measurement in shallow waters with under keel clearance as little as1

meter, enabling close control of speed for safe berthing and anchoring operations.

• •Ground tracking speed measured between 1 and 200 meters for accurate speed measurement in

coastal waters.

• •Wide variety of both analog and digital displays optionally available for remote monitoring.

• •Analog speed data and distance run signal, fed to various onboard equipment for improving

bridge automation.

• Conforms to the following standards: IMO A.824(19), as amended by MSC.96(72),

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