FOREWORD

A Word to FE-700 Owners

Thank you for purchasing this navigational echo sounder. 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 navigational echo sounder 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 FE-700 is comprised of display unit and transducer unit. Echo sounding data is displayed on the bright 6.5-inch color TFT (Thin Film Transistor) LCD display.

The main features of the FE-700 are

1. Complies with the IMO and ISO standards

MSC.74(69) Annex 4 and ISO9875.

2. Cost-effective; no paper, no consumables; high accuracy and high reliability - no rotating gears and belts as in the paper echo sounders

3. High-contrast 6.5-inch color LCD display featuring a wide viewing angle and adjustable brightness.

4. Wide variety of modes with never-get-lost default position.

5. Automatic function permits unattended adjustment of range, gain, and pulselength. The range scale and gain automatically change to display the bottom.

6. Position, course, speed, time are repeated from the external devices.

7. Alarms: shallow water, bottom lost, power drop

PRINCIPLE OF OPERATION

The FE-700 uses ultrasonic pulses to detect the seabed and other underwater objects. The display unit contains all basic electric circuits and logic processor. Electrical pulses are converted into acoustical energy in the transducer fitted on the ship’s hull. The processor measures the time of pulses travelling between the seabed and transducer and displays the water depths in the graphical form or other forms.

The transducers have a specific beam width with respect to their working frequency, 50 kHz or 200 kHz. The high frequency has a narrow beamwidth and is immune to aeration when the ship is going astern or in rough weather. The low frequency has a wide beamwidth and more powerful sounding capability.

2. Set as follows by using [▲] or [▼] to select

an item and [+] or[-] to set option.

a) If only one transducer is installed, set

XDR FORE field to 50 kHz or 200 kHz, according to actual installation. Leave the XDR AFT field as “N/A.”

b) If two transducers are installed via the

switch box EX-8, set XDR FORE field and XDR AFT field to 50 kHz or 200 kHz, according to actual installation.

3. Reset the power.

Note: The default settings in the TRANSDUCER SETTING window are N/A. At the first power-up after installation, the window appears to set transducer(s).

! To return to the normal operation, select

OFF at step 4 above. Restart the display unit after waiting 5 s.

4.3 Bottom Level

If the depth indication is unstable or the seabed cannot be displayed steadily notwithstanding the adjustment of the control panel, you may adjust the bottom echo level.

CAUTION

If the level is set too low, the FE-700 may not be able to distinguish the bottom from fish echo and the depth indication may be unstable and if set to high the depth indication does not appear.

1. Press the MUTE A LARM key three times at

the EXTENSION MODE. The start-up screen appears and shortly thereafter the BOTTOM LEVEL display appears.

default level is 80.

3. Press the POWER switch to finish the

adjustment. Wait about 5 s and then turn on the power again.

4.4 TVG Level

TVG (Time Varied Gain) compensates for propagation attenuation of the ultrasonic waves, reducing surface noise to provide a smooth display. The TVG lowers receiver sensitivity at the time of pulse emission and gradually increases it with time, thereby making objects of same reflectivity at different depths appear at the same intensity or colors on the display. The TVG working depth is down to approximately 150 m on the 200 kHz system and 350 m on the 50 kHz

6 MAINTENANCE, TROUBLESHOOTING

6.3 Transducer Maintenance

WARNING

Do not open the cover.

There are no user-serviceable parts inside. Refer any repair work to a qualified technician.

6.1 Checking

Regular maintenance is essential for good performance. Checking the items listed in the table below on a regular basis will keep the equipment in good shape for years to come.

Item Action Cable run

Power cable, transducer cable plug

If conductors are exposed, replace cable.

If loosened, tighten.

Marine life on the transducer face will resu lt in a gradual decrease in sensitivity. Check the transducer face for cleanliness each time the ship is dry-docked. Carefully remove any marine life with a piece of wood or fine-grade sandpaper.

6.4 Replacing the Fuse, Battery

If a fuse blows, find the cause before replacing it. Use only designated fuses. Using the wrong fuse will damage the unit and void the warr ant y.

Three types of fuses are used in the distribution box FE-702.

For Display Unit : 3 A x 1 pc (24 VDC) For Digital Depth Indicator: 0.5 A x 2 pcs For AC input: 1 A x 2 pcs

The Digital Depth Indicator FE-720 uses one fuse of 1 A, w hich is inserted in the positive line of interconnection cable.

Display unit ground If corroded, clean. Ship's mains voltage If out of rating, correct

problem.

6.2 Cleaning the Display Unit

Dust or dirt on the display unit should be removed with a soft cloth. If desired a water-moistened cloth may be used. Do not use chemical cleaners; they can remove paint and markings.

A batt ery installed on a circuit board inside the display unit preserves data when the pow er is turned off. The life of the battery is about t hree years. When the battery voltage is low, “battery” NG appears at the self-test. When this happens, contact your dealer to request replacement of the battery.

TYPE Code Number Lithium Battery CR2450-F2 ST2 000-133-495
