Power Off
Press the TRANSDUCER “ ” switch on the control box. Wait until
the lamp above the switch lights, and then press the POWER “ OFF ”
switch. Note that the transducer automatically retracts into the tank
even if the
POWER “ OFF ” switch is pressed without raising the
transducer (by pressing the TRANSDUCER “ ” switch). However,
for safety purposes, it is recommended that you make a habit of press-
ing the
TRANSDUCER “ ” switch first to ensure that the trans-
ducer is retracted.
Lowering the Transducer
Press the TRANSDUCER “ ” switch. The lamp above the switch
flickers, and then lights when the transducer is fully lowered.
CAUTION CAUTION
Observe maximum allowable ship’s
speed of 18 knots during operation and
16 knots while raising/lowering
transducer.
Selecting a Display Range
The RANGE switch on the control box is used to select a display
range. The range selected is displayed at the top center of the screen.
Setting the Tilt Angle
The tilt angle shows the direction to which the sound wave is emit-
ted. When the sound wave is emitted horizontally, it is said to be zero
(0) degrees and when emitted vertically, 90 degrees. To set a tilt angle,
operate the
TILT lever for the desired angle while watching the tilt
angle indication at the top right-hand side of the screen. The tilt angle
can be set in one-degree steps within the range of 0 to 55 degrees.
Finding the proper tilt angle is of utmost importance when searching
for fish. This unit, because of its compact size, is highly suited to
coastal water fishing where the depth of the main fishing ground is
from 50-l00 m. In this type of fishing ground it is imperative that the
seabed echo be always displayed to properly distinguish between fish
and the seabed. When selecting a tilt angle, keep the following points
in mind.
