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.

selection is shown in the range display window.

RANGE 5 m

In the AUTO mode, the range scale is

automatically adjusted. See section 1.9 for

details.

1.8 Gain Control

The GAIN Control adjusts the sensitivity of the

receiver. The AUTO mode provides automatic

adjustment and you are normally not required to

adjust it. Current setting is shown at the upper

left-hand corner. Adjust the GAIN Control and the

following window appears.

GAIN 5.5

Adjust the GAIN Control so that a slight amount

of noise remains on the screen. Generally, use a

higher gain setting for greater depths and a lower

setting for shallower waters. Adjusting range is

between 0.0 and 10.0 in 0.5 steps.

1.9 Automatic Operation

The automatic function automatically selects the

proper gain, range scale and clutter level

according to depth. It works as follows:

• The range changes automatically to locate the

bottom on the lower half of the screen. It jumps

to one step shallower range when bottom

echoes reach a halfway point of the full scale

from top and to one step deeper range when

they come to the lower edge of the scale.

• The gain is automatically adjusted to display

the seabed in specified color.

• Clutter level (on the menu), which works as a

threshold control to suppress overall noise, is

automatically adjusted.

Note: The AUTO MODE is cancelled whenever

the range or the gain is changed.

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

system. Outside this range the echoes from the

seabed and fish schools are received in full level.

There is no perceivable deterioration in

performance.

6 MAINTENANCE, TROUBLESHOOTING

Do not open the cover.

There are no user-serviceable parts inside.

Refer any repair work to a qualified

technician.

WARNING

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

If conductors are

exposed, replace

cable.

Power cable,

transducer cable plug If loosened, tighten.

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.

6.3 Transducer Maintenance

Marine life on the transducer face will result 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 warranty.

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, which is inserted in the positive line of

interconnection cable.

A battery installed on a circuit board inside the

display unit preserves data when the power is

turned off. The life of the battery is about three

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
