1. MOUNTING
1.1
Display Unit
Mounting considerations
• Locate the unit out of direct sunlight.
• The operator should face the bow while viewing the display screen.
• Select a location where the display screen can be easily observed while operating the control
panel.
• Leave sufficient space around the unit for maintenance and servicing. Recommended mainte-
nance space appears in the outline drawing at the back of this manual.
• Observe the compass safe distances on page ii to prevent deviation of a magnetic compass.
The display unit can be mounted on the tabletop or on the panel (flush mounting). Mount the unit,
referring to the outline drawing at the back of this manual.
1.2
Transducer
The performance of the echo sounder depends upon the transducer position. A place least affect-
ed by air bubbles should be selected since turbulence blocks the sounding path. Further, select a
place least influenced by engine noise. It is known that air bubbles are fewest at the place where
the bow first falls and the next wave rises, at usual cruising speed.
Note:
The face of the transducer must be facing the sea bottom in normal cruising trim of the boat.
NOTICE
Do not apply paint, anti-corrosive sealant
or contact spray to coating or plastic
parts of the equipment.
Those items contain organic solvents that
can damage coating and plastic parts,
especially plastic connectors.
WARNING
Turn off the power at the switchboard
before beginning the installation.
Fire or electrical shock can result if the
power is left on.
