There is a risk of electrical shock if you touch the high voltage
conductors.
Only qualified personnel should work inside the unit.
Care for sufficient reinforcement and being watertight should be
taken when installing the Hull unit.
Otherwise, it will cause wrecks.
Use the proper fuse when changed.
Otherwise, it could result in serious trouble or fire.
Use the specified power supply cables.
Otherwise, it could result in serious trouble or fire.
The Hoist Gears and Flange unit need a regular lubrication with
grease.
TFT LCD
The high quality TFT (Thin Film Transistor) LCD displays 99.99% of its picture elements.
The remaining 0.01% may drop out or light, however this is an inherent property of the
LCD; it is not a sign of malfunction.

SONAR SYSTEM SUMMARY
SONAR MODE
A sonar system uses the transmitter-receiver as well as an echo sounder.
An echo sounder is only able to search in one direction, down.
However, a sonar has a movable transducer and therefore can freely search the entire
around a ship, not just the area directly beneath the ship.
When the sonar is not operated, the transducer is retracted.
While operating, the transducer is protruded from the hull bottom.
An ultrasonic pulse is emitted from the transducer protruded from the hull bottom.
The sonar principle detected by the transducer is the same with the echo sounder.
However, like a searchlight, the sonar transducer sends and detects ultra-sound
beams one after another while giving relative bearing at some speed in proper ranges.
The transducer scans or trains with the step angle set at MENU.
The seabed and fish school will send a reflected echo of sound back to the ship.
In a PPI sonar, this reflection with relative bearing and range information is presented
like a radar screen.

1-3
SONAR SYSTEM SUMMARY
An echo sounder is only able to search in one direction within some beam angle, beneath
the ship. A sonar, however, can freely search the broad range, since the transducer’s
angle can be varied not only the horizontal direction but also the vertical direction.
By changing the horizontal angle (Sector), the various ranges from the narrow to the full
circle are available
By changing the transducer’s directional angle (Tilt), the ultra-sound beam angle can
be varied from right beneath the ship to the horizontal direction.

1-4
SONAR SYSTEM SUMMARY
TILT ANGLE
The tilt angle shows the direction to which the sound
wave is emitted. The tilt angle can be set in step of 1°
from 0° to +5° (upward) to 0° to 90° (downward).
Find out the suitable tilt angle for a given depth and
detection range.
The tilt angle is of importance when working with sonar.
Refer to the illustration below. Find out the suitable tilt angle and beam coverage.
When the ship approaches B with the same tilt angle, the reflection is getting smaller
and weaker gradually and nothing appears at B position.
Without changing the tilt angle, the fish school is out of beam coverage at B position
so that no reflection appears on the screen. Set an appropriate tilt angle so that the
reflection of fish school always appears on the screen.
The narrow tilt angle is selected for surface detection, however, if 0° is selected,
sometimes the reflection of the sea surface appears on the screen as the noise and
interferes with observation of wanted echoes.
Adjust an appropriate tilt angle to lessen the effect of sea surface reflection.
The Tilt angle is also set in the Bottom Scan mode and the Echo Sounder mode.
