Installation
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.
Transducer Installation
If you have chosen a Sonar option for your Echo sounder a transducer must be installed on your
vessel unless an exiting compatible transducer is installed. The installation of sonar transducers
require some planning and skill to achieve the best result. It is strongly advised hat you read the
installation instructions completely before starting. The two basic types of transducers are transom
mount and through-hull mount. There are variations within each type to provide for options such as
temperature sensors, speed sensors and for different beam angels and sonar frequencies. Several
different transducers may be used with the JFC-7050. Refer to the optional Equipment list for the
variations available.
CAUTION
Mounting a sonar transducer for your JFC-7050 Sonar requires drilling holes into the hull of your boat
which could affect its water integrity. Therefore, installation should be attempted only by qualified
individuals. If you have any doubt about your ability to complete the process successfully, we
recommend you obtain the services of a JRC dealer or marine service center with knowledge and
experience in transducer installation.
Since your JFC-7050 Sonar performance depends upon how well the transducer is installed, please
carefully observe the following mounting procedures.
For proper performance, the transducer’s mounting location must be chosen carefully. The transducer
must be mounted in a location that is free from turbulence and air bubbles created by movement of the
boat through water. Air bubbles greatly reduce the efficiency of the transducer. It is also strongly
