Battery Replacement Information
The computing unit of this system uses batteries for storing start-up information.
Replace the batteries periodically. Using batteries near the end of their life may cause
not only start-up failure, but also problems such as emitting smoke, catching fire or toxic
leakage.
Standard replacement time
The standard battery life is approximately 6 years. If the batteries are used at high
temperatures, the battery life will be shorter. We, therefore, recommend replacing the
batteries once every three to four years.
Replacement method
For the method of replacement, please contact our service staff.
Safety and Handling Instructions
Before using this system, please read this instruction manual carefully to
gain a thorough understanding and ensure safe and correct operation.
For system maintenance, please contact our repair and service staff.
Do not allow anyone except our repair and service staff to disassemble
and repair this system.
Please keep this manual on hand at all times.
Pictorial Symbols
In this instruction manual as well as on the product, pictorial symbols are provided
to indicate how to use our products correctly and to prevent injuries to users and
damage to their assets. Users are required to comply with the following instructions.
The indications of the pictorial symbols are as follows:
Indicates that “there is a high probability of causing death or
serious injury to users if not handled properly”
Indicates that “there is a risk of causing death or serious injury
to users if not handled properly”
Indicates that “there is a probability of causing moderate or
minor injury if not handled properly”
Batteries are valuable, recyclable resources. Please cooperate in recycling
used batteries.

Caution
Caution for installation sites
(1) Avoid using this system in a place that may reach high temperatures of
50°C or more, such as in direct sunlight or near heating systems for a long
period of time.
(2) Avoid using this system in a place that is humid or exposed to direct
splashes from waves.
Caution for inspections of the ship bottom and equipment
While inspecting the ship bottom, wear a helmet and safety shoes.
Inspections must be performed with two or more persons to ensure that contact
with the outside is possible, whenever necessary.
Warning
Danger
Prevention of an electric shock accident caused by the high-
pressure sections
(1) Before checking inside the system for maintenance and inspections, ensure
to turn OFF the power switch because some sections use high voltages.
(2) Before checking inside the system for maintenance and inspections, wash
your hands to remove any salt. If your working clothes and shoes are wet,
change them for dry ones.
(3) If someone around you is electrocuted, avoid direct contact because it may
lead to a risk of an electric shock. Alert everyone in a loud, calm voice, and turn
OFF the power switch or use a piece of wood to help. Then, use artificial
respiration or other general means of resuscitation.

Introduction
Echo sounders are designed to transmit sonic waves from a transducer and
receive the echo reflected from fish or the bottom of the sea. On previous echo
sounders, images were adjusted by the TVG volume and gain volume, so that
the reflected echo could easily be seen on the echo sounder picture.
This Fish Sizing Echo Sounder needs no TVG volume adjustment, and it
automatically and accurately corrects the sonic wave attenuation under the sea.
Fish schools of the same density are displayed in the same color regardless
of the depth. The features of this system are described below.
<Features>
・Detection of a single fish with high accuracy.
・Controller designed for this system.
・Data recording function installed as the standard feature (row data)
・High precision digital TVG
・Function to determine the sea bottom level
・Supports a dual monitor
In addition, for fish length measurement, which is one of the features of this
system, the split beam method is adopted. The split beam method detects the
level of a single fish (only one fish) with a main receiving beam, and detects the
direction ofthis single fish with 4receiving beams. Bydetecting thefish direction,
the effect of the directive property that is peculiar to ultrasonic waves can be
corrected. Thus, fish length measurement free from the effects of directive
property is possible with high accuracy. For accurate fish length measurement,
please use the following information for reference.
<To accurately measure the fish lengths>
(1) Outside noise reduction
The Fish Sizing Echo Sounder uses faint signals so that the measurement
accuracy can decrease when there is significant outside noise (running noise,
interference, etc.). For such cases, measures are available, such as reducing

I-8
the ship engine rotation to create an environment with less running noise, or
stopping audio systems that are not in use.
(2) Measurement accuracy enhancement
Making manymeasurements of the same fish school can enhance the accuracy
of the fish length. Examples of making such measurements include “reducing the
ship speed” and “changing the range of the Fish Sizing Echo Sounder to the
minimum value.”
