Before You Begin ii

Usage Hints
Do not remove the cover of this set. Otherwise, you
may touch a high-voltage part and suffer from an
electrical shock.
Do not dismantle or modify this equipment. Failure to
observe this warning may result in fire, electric shock, or
damage.
Do not place any vessels containing water or other
liquids, or metal objects, on top of this equipment. If
water is spilled on or metal objects fall into the equipment
there is a risk of fire, electric shock, or damage.
Do not insert or remove the power cord or operate
switches with a wet hand.
Otherwise, you may suffer from an electrical shock.
Usage Hints iii

Do not damage, break or modify the power cord.
When a heavy object is placed on the cord or the cord is
heated, pulled, or forcibly bent, the cord will be broken
resulting in a fire or an electrical shock.
Do not use this set at a voltage other than the supply
voltage stated on the set.
Otherwise, a fire, an electrical shock, or a failure may
occur.
In the event of water of metal objects falling inside the
equipment, immediately turn off the power switch, then
contact JRC or its agent.
There is a risk of file or electric shock if you continue to
use the equipment.
If you notice smoke, unusual smells, or abnormal heat
coming from the equipment, immediately turn off the
power switch, then contact JRC or its agent.
There is a risk of fire, electric shock, or damage if you
continue to use the equipment.
There are no customer-serviceable parts inside. Unauthorized inspections and
repairs could cause fires and electrical shock hazards.
Please call our field representative or your nearest JRC office for inspection and
repair services.
Use only the specified fuses.
The use of other fuse may cause fire and/or damage.
The Main switch on the CQD-2082 I/F unit must be turned off during replacing a
fuse.
Usage Hints iv

Please contact JRC or its agent for the electrical
installation of this equipment. Electrical installations
carried out by other than the qualified staff may result in
faulty operation.
Do not install or operate the equipment where subject to
temperatures more than 55or less than -15. High
temperature may cause failures.
Do not install the equipment on unstable or unleveled
surfaces. Failure to observe this condition may result in
the equipment falling or toppling over, resulting in injury.
If it is cold, do not move the equipment suddenly into a
warm environment and switch it on. High-voltage leaks
due to condensation may result in damage to the
equipment. In such situations, leave the equipment in
the warm environment for about 30 minutes before
switching it on.
When installing the equipment, securely connect the
earth lead to the earth terminal. Failure to connect the
earth may result in electric shock in the event of a fault or
power leak developing.
㪞㪥㪛
Do not turn on the equipment's power when the ship is in
dry docks.
Failure to observe this caution may result in damage to
the transducer, etc.
Usage Hints v

When removing the power cord, be sure to remove the
power cord terminal correctly.
If the power cord is pulled, the cord may be damaged
resulting in a fire or an electrical shock.
Do not install the units on the place being poor
ventilation.
Otherwise, the set that is heated may cause a fire or
failure.
For safety when the equipment is to be left unused for an
extended period, turn off the power switch.
When turning on the power, be sure not to press any operator panel key at the
same time. Alternates to the hardware configuration of the until could cause
the unit to malfunction.
Take care when laying the transducer cable, power cable, and earth lead as
positioning has an affect on electromagnetic interference. There is a risk of
interfering with other equipment or the echo-sounder being interfered with by
the other equipment.
After installing the echo-sounder, turn on the power to all other equipment to
check for interference with or from all the equipment. Interference may cause
malfunctions.

Explanation of Terms
Beam angle: The angle that sound waves spread out from the transducer. Sound waves
spread out in a conical manner taking the center of the bottom surface of the transducer at
the apex of the cone.
Bubbling: The phenomenon where the image of the seabed is interrupted due to air bubbles
caused by the ship's hull or the propeller during a voyage.
IMO: abbreviation for the International Maritime Organization.
MED: abbreviation for the Marine Equipment Directive. This is the directive for marine
equipment in Europe. This directive unifies format approval standards implemented
separately by each European.
NMEA0183: formats for the National Marine Electronics Association. NMEA0183 is the
format used when sending or receiving depth, position, water temperature, ship speed and
other information between marine equipment.
STC: Sensitivity Time Control is used for reduce shallow water clutter. Shallow seabed
echo is strong and deep seabed echo is weak. So, the STC controls the sensitivity to
normalize seabed echo for precision seabed tracking.
Transducer: Device that emits ultrasonic waves in water and receives the signals reflected
off the seabed. This is equivalent to an antenna on a radio.
UTC: abbreviation for the Universal Time Coordinated.
