Installation Notes – Transducer for Speed and Temperature Only

This type of transducer may be used with a thru-hull transducer which reads depth only. The speed/temperature transducer is attached to the transom of the boat. Detailed instructions for this installation will be included with the transducer. The cable for this transducer uses a “Y” connector. See the notes on “Installing the Transducer Cable.”

EMC Installation Guidelines

When different types of marine electronic equipment are mounted closely together in a tight space, they may interfere with each other. The design and manufacture of this unit follow industry standards for “Electromagnetic Compatibility” (EMC). However, it is important to install the unit correctly to ensure the best possible performance. Below is a list of some of the factors which could affect the operation of the product. Some of these factors may affect the way you install the FishFinder and the wiring cables.

Place the display unit and the power and signal cables at least 3 ft. (1m) from any equipment transmitting radio signals, or any cables carrying radio signals. This includes VHF radios, cables and anten- nas. In the case of SSB radios, the distance should be increased to 7 ft. (2m).

Allow a space of at least 7 ft. (2m) from the path of a radar beam. Normally, a radar beam will spread about 20° above and below the radiating element.

The power for the display unit should be supplied from a different battery than the one used to start the engine. If the voltage to the FishFinder unit drops below +10.8 V DC, this could cause the unit to reset. This will not damage the equipment, but it may cause the loss of some information, and it can change the operating mode.

Avoid running the FishFinder power wires near the power wiring for any radar, radio, or Loran-C units. If possible, wire the FishFinder power wires to a separate circuit breaker.

If the transducer cable runs near another electrical wire, it may pick up electrical interference or “noise.” To reduce this, try to keep the
