Optional Temperature Sensor

2.The epoxy consists of the epoxy itself and a hardener. Remove the two compounds from the package and place them on the paper plate.

Thoroughly stir the two compounds together until the mixture has a uniform color and consistency. Do not mix too fast or bubbles will form in the epoxy. After mixing, you have 20 minutes to complete the installation before the epoxy becomes unworkable.

Spread a thin layer of epoxy (about 1/16" or 1.5 mm thick) on the face of the transducer as shown in the previous figure. Make sure there are no air pockets in the epoxy layer! Then, apply the remaining ep- oxy to the sanded area on the hull.

3.Press the transducer into the epoxy, twisting and turning it to force any air bubbles out from under the transducer face. Stop pressing when you bottom out on the hull. When you're finished, the face of the transducer should be parallel with the hull, with a minimum amount of epoxy between the hull and transducer.

4.Apply a weight, such as a brick, to hold the transducer in place while the epoxy cures. Be careful not to bump the transducer while the ep- oxy is wet. Leave the weight in place for a minimum of three hours. Allow the epoxy to cure for 24 hours before moving the boat.

5.After the epoxy has cured, route the cable to the sonar unit and it's ready to use.

Speed/Temperature Sensors

All the units in this series can display water temperature from a single analog sensor. Your unit comes packed with a transducer with a temp sensor built into it. If you wish to purchase an optional additional sen- sor for your unit, refer to the accessory ordering information inside the back cover of this manual. These units use the TS-1BL temp sensor.

However, please note that the Sonar socket on your unit is designed to read only one temp sensor. Since your transducer contains a built-in temp sensor, attaching the TS-1BL to your unit's Sonar socket will over- ride the temperature information provided by the transducer's temp sen- sor. Your unit will only display the temperature provided by the TS-1BL.

Optional Speed Sensor Installation

All the units in this series can display speed and distance traveled, but only the X105C DF comes packed with a speed sensor. If you wish to purchase an optional additional sensor for your unit, refer to the acces- sory ordering information inside the back cover of this manual. The following instructions describe how to install the SP-BL speed sensor.
