Transducer Installation
Prior to installing the transducer review the
Selecting the
Transducer Configuration guidelines on Page 9.
The iScan V90 comes standard with either a thru-hull or
transom mounted forward scanning transducer. It is
important to position the transducer so that it has as clear a
view as possible of the water directly below and ahead of
your boat, as indicated at left.
The scanning transducer must be positioned properly so that
it scans in the proper direction (i.e. from in front of the boat
to the bottom below). The sketch at left shows the proper
orientation for both the transom mount and thru-hull
transducer.
NOTE THAT ON THE TRANSOM MOUNT
TRANSDUCERS, THE ROUNDED SIDE MUST POINT
FORWARD, AND ON THE THRU-HULL
TRANSDUCER, THE MORE BLUNT AREA MUST
POINT FORWARD.
General Considerations
DO NOT CUT OR SPLICE YOUR PHASED ARRAY
TRANSDUCER CABLE OR REMOVE THE 9-PIN
CONNECTOR BECAUSE THE SYSTEM
PERFORMANCE MAY BE SERIOUSLY DEGRADED.
THIS ACTION WILL VOID YOUR WARRANTY.
If you need a longer length cable than comes with the
transducer (30’), then purchase the optional 30’ extension
cables,
Interphase Part # 04-0014-008. It is recommended
that only one extension cable length (total of 60’) be used as
additional extensions will decrease the effective power and
depth range.
1) Choose a location where there is the least amount of
acoustic noise, air bubbles or turbulence caused by the boat’s
movement. The transducer should not be located nearby or
especially directly behind the propeller.
2) Choose a location where the transducer can be mounted
so that it will be level to the water’s surface and will not be
tilted to either side. Otherwise the transducer will not scan
from the surface ahead to directly beneath the boat.
3) The transducer must always remain submerged,
regardless of the speed of the boat and should not be
mounted where it could be damaged by underwater obstacles
