Direction of the bow
mark
• The bow mark on the transducer and flange assembly should be faced to
the ship’s bow. If not faced to the bow, target echoes may not be dis-
played correctly.
Wiring check
• All cables are correctly connected.
• All screws (ex. cable clamp screw, ground terminal) are firmly fastened.
• Cables are firmly secured.
• Cable shields are properly grounded.
Rejecting source of
noise and interference
• Noise generating machinery (motor, radiotelephone, TV set, etc.) are not
placed nearby.
Ground
• Each unit is grounded correctly.
Note:
The ground terminal should be connected to ship’s ground. If the
ground terminal is connected to the terminal other than the ship’s ground
(ex. main engine), electrolytic corrosion may occur.
Ship’s main voltage
• Ship’s main voltage is stable 12 or 24 V DC.
Watertightness
• Water should not leak from the flange assembly or cotton retainer.
Heading alignment
• A target echo is displayed on the correct bearing. For how to adjust head-
ing alignment, see section 3.3.
