resistance of the hoisting device. When used in excess of the ship speed
resistance, the hoisting device may be damaged and cause an accident.
Ship speed
resistance
18 knots
・Change electrolytic corrosion-preventing zinc plates annually.
Be sure to perform electrolytic corrosion prevention. If electrolytic corrosion
prevention is not performed, the transducer may fall accidentally or there may
be an influx of seawater into a dome, in the worst case.
For the transducer
The transducer of this sonar system is filled with castor oil inside. This castor
oil may steep from the transducer cable due to outside temperature change,
but it does not affect the performance.
For preventing damage at sea
When the transducer or the hoisting device is damaged at sea, the sonar
system cannot be used, accordingly, the operation or safe navigation is
sometimes hindered. Furthermore, it takes a large amount of time and cost to
exchange and repair the transducer or the hoisting device.
In order to prevent these accidents from occurring, store the transducer by
performing the following operations when conditions are as described below.
1. Condition
1) Sea condition with many float and drift
2) The case of getting out of an encircling net by a lightship of round haul
netter fleet
3) A shallow place where ropes or wires are set up under seas
4) During an anchorage of a ship

vii
2. Transducer storage operation
1) Press the “ascend” key of the hoisting device on the controller and store
the transducer.
2) During ascending, an arrowhead “” is indicated in upper right of the
screen and the display bar of the hoisting amount is gradually reduced.
3) When the transducer is stored and the hoisting device goes up to the upper
limit, the upper limit message is displayed and the hoisting device stops.
On the battery·electric cell exchange
In this instrument, a battery is used to have clock function. Perform exchange
of a battery periodically.
Be sure to change any expired batteries. If you leave a battery unchanged,
there is a risk of smoking and ignition.
＜Target of exchange＞
As to a battery, the target life is set to about two years as a standard. When the
battery is used under a high temperature, the life becomes shorter.
＜Exchange method＞
As to the exchange of a battery, make contact with our service personnel.
Batteries are valuable and recyclable resources. In changing batteries and
used product disposal, cooperate in recycling.

Chapter 1 Outline of Basic Operation
1.1 Emergency stop
In case of the occurrence of an abnormal situation, such as "power supply not cut off"
even though you cut off the power ON key ( ), “keys of the controller do not function,”
or “sonar action stopped,” press the power ON key ( ) and power OFF key ( ) of
the controller at the same time so as to cut the power supply of the entire system.
When the power supply is cut off by the emergency stop switch, the hoisting device goes
up automatically to store the transducer. Apply the power again, and then check if the
transducer is safely stored, for the prevention of danger.
When the power supply cannot be applied again, store the transducer using the manual
operation of the hoisting device. For the method of manual operation, refer to Chapter 7
Operation and Maintenance of the Hoisting System.

the transmission is automatically stopped by the operation of "AUTO TX"
(effective when "TX" in "MENU" is set to "AUTO").
(b) Press the power OFF key ( ) to cut the power supply.

1-2
(Note)
If you cut the power switch without storing the transducer, the storage
operation of the transducer is automatically performed by the "Automatic
ascending operation." After storing the transducer up to the upper limit,
the power supply is automatically shut off. In addition, when cutting the
power supply for safety, cut the power supply after storing the transducer.
1.2.2 Descent and ascent of the transducer
(1) Projecting the transducer
Press the descending key ( ) of the controller to lower the transducer.
During the descent operation of the transducer, the upper lamp of the descending
key ( ) flashes on and off. Also, during the descent operation, "↓" is displayed
at the left of the hoisting amount indication.
When the operation is performed up to the lower limit, the hoisting amount
indication is displayed as being completely filled and the upper lamp of the
descending key ( ) is turned on. Further, the lower limit message is displayed
on the screen.
When the hoisting amount has reached the lower limit, the transmission is
automatically stopped by the operation of "AUTO TX" (effective when "TX" in
"MENU" is set to "AUTO").
(2) Storing the transducer
Press the ascending key ( ) of the controller to store the transducer.
During the ascent operation of the transducer, the upper lamp of the ascending
key ( ) flashes on and off. Also, during the ascent operation of the transducer,

1.2.4 Gain adjustment
The receiving gain is adjusted by the GAIN keys ( and ) of the controller.
The gain can be set in the range of 0.0 to 10.0 The gain is raised by the key
and lowered by the key. The gain is adjusted such that the fish school echo
clearly appears on the screen and the noise is minimized. In addition, this instrument
executes the gain control for the TVG; if the distance is increased, the gain is
automatically increased. By virtue of this, fish schools at both long distance and short
distance are displayed similarly on the screen.
1.2.5 Tilt adjustment
The tilt is adjusted by the tilt keys ( and ) of the controller. The tilt can be set
by 1° (degree) in the range from +5° (to the upward direction from the horizontal
direction) to -60° (to the downward direction from the horizontal direction).
The tilt is adjusted to the upward direction by the key and adjusted to the
downward direction by the key. The angle is adjusted to the direction where you
want to search for fish schools.
For the tilt adjustment operation, there are four modes: Manual, Auto, One shot, and
Track.
1.2.6 Range adjustment
The range can be adjusted with the range keys ( and ) of the controller.
The range can be set to a long distance with the range key and to a short
