1.6 Installation of transducer

1.6.1 Transducer installation

The transducer should be installed in a location free of bubbles and away from disturbed
water flow. Smooth water flow around the transducer and along its surface are very important
for consistent operation. Areas in the center of water line length at cruising speed are usually
satisfactory. Forward of the engine and in a flat area near the center line of the boat are
preferred. Do not install the transducer behind water intakes, other through-hull fittings or
irregularities in the hull.

1.6.2 Through-hull installation

Transducer installation for CVS-705D/707D is only possible with through-hull installation.
Various types of rectifying tanks (Turbulence Minimizing Enclosure) are prepared according to
the material of the ship’s hull or transducer frequency used. Mount the rectifying tank to the
ship’s bottom before mounting the transducer to in the rectifying tank. The more the tank
protrudes, the less the water turbulence.

[Output Limit] is a common setting
regardless of CM key.

A set value of [TX Power] is applicable
individually to each CM key.

[Output Limit] limits the output that becomes
the source of [TX power].

The value of [TX Power] represents the
percentage out of the value set by [Output
Limit] as 100%.

For instance, when the value of [Output
Limit] is 60, and the value of [TX Power] is
90, actual output is 90% of the output limited
to 60% from the original output power.
