operation
Descent 15 knots or
less
ship speed
resistance
16 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 can not 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

2. Transducer storage operation
- Press the “ascend” key of the hoisting device on the operating portion and store the
transducer.
- During ascending, an arrowhead “” is indicated in upper right of the screen and the
display bar of the hoisting amount is gradually reduced.
- 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.
Fan Motor Replacement
This system is designed to prevent internal temperature increase in the processor, receiver
and transmitter by installing fan motors in them. If those fan motors are not working, an
increase in the internal temperature of those devices may cause their malfunction. The
outlets of the fans, therefore, should be inspected regularly to check that the fan motors are
working properly.
Although the service life of the fan motors in general is 50,000 hours, it varies depending on
the use environment. For this reason, fan motors must be replaced periodically.
<How to Replace>
For replacement of the motor fans, please contact our service engineers.
