Installation Display unit brings expandable display technology to your bridge or navigation station. A careful installation will assure maximum benefit from Display unit integrated features. Display Unit Location Select a location for your Display unit that provides easy viewing from all likely operator’s positions. The display unit is designed to be mounted on either a console or from an overhead surface.
Installation Drill a 1/4 in. diameter hole at each marked location. Mount the Display unit bracket using bolts through the mounting surface. Place large flat washers on the opposite side of the mounting surface from the bracket and then install lock washers and nuts. Tighten securely. Install the display unit into the mounting bracket.
An input designation means, in put to Echo sounder unit and an output designation means, output from JFC-7050. Sensors will have similar designations, but from the sensors point of view. Therefore, a sensor output will connect to an JFC-7050 input and a sensor input will connect to an Echo sounder unit output.
For boats with poor water flow under the transom or on in-boards, consider selecting a through-hull transducer. JRC offers many styles of transducers. Determine the transducer mounting place by referring to the steps mentioned above. For best result, the transducer face should be level.
Through-hull transducers are recommended for in-boards and other vessels with disturbed water flow under the transom. JRC offers several models of bronze through-hull transducers. To enjoy the full capability of your Sonar, select a dual frequency model with temperature sensor. Sturdy bronze construction assures a secure installation and provides a strong base for fairing blocks, if needed, to compensate for hull shape.
Installation Dead-rise On hulls with dead-rise of 5 or less, the transducer may be mounted directly through the hull. Where dead-rise is greater than 5, fairing blocks must be used to orient the face of the transducer parallel with the water surface. In this case, no fairing block is necessary.
Installation Through-hull Transducer Maintenance If your boat is kept in the water, performance of your JFC-7050 Sonar will be adversely affected by accumulations of sea growth on the face of the transducer. To prevent sea growth effects, the face of the transducer may be coated with antifouling paint specially formulated for transducers.
