1. 4mm bit drill the two holes to a depth of approximately 1 3cm On fiberglass hulls it is best to start with a smaller bit and use progressively larger drill bits to reduce the chance of chipping or flaking the outer coating Step Three Assemble the Transducer 1 Attach the Pivot to the transducer body as shown in Figure 5 using the 8 3 8 9mm long allen headed pivot screw the headed pin the two flat washers and the two toothed lock washers Note The toothed lock washers must be positioned between the transducer and the pivot ears The flat washers must be positioned to the outside at the pivot ears 2 Using the Allen wrenches provided loosely tighten the pivot screw Figure 6 Do not completely tighten the assembly at this time so the pivot angle can be adjusted later Insert the pivot transducer assembly into the mounting bracket as shown in Figure 7 Do not snap the assembly closed Template alignment Transducer Assembly INSTALLATION TRANSOM INSTALLATION Step Four Mount the Transducer to the Transom 1 Apply silicone sealant to the mounting holes drilled into the transom 2 Align the transducer assembly with the drilled holes in the transom Figure 8 3 Use either a flat head screwdriver a 5 16 8mm hex driver or a 5 16 8mm socket to mount the assembly Using the two 10 1 25mm long slotted hex head screws mount the transdt fe assembly to the transom as s2. Your Humminbird is now ready for operation INSTALLATION TEST THE INSTALLATION TEST THE INSTALLATION Testing should be performed with the boat in the water however you can initially confirm basic operation with the boat trailered Press POWER once to turn the unit on There will be an audible chirp when any button is pressed to confirm the button press If the unit does not power up ensure the unit is fully seated on the mount and that power is available The first screen provides four options Start up Options Simulator and Diagnostic A message at the bottom of the screen indicates the transducer connection If no transducer is detected or one is not connected the message will indicate this and the unit will go into simulator after the initial screen times out Note the transducer must be submerged in water for reliable transducer detection If a transducer is detected the unit will enter Start Up or normal operation unless you choose another option If you do not press any button before the timer reaches 0 the normal operation screen is displayed If the boat is in water sonar data appears If the bottom is visible on screen with a digital depth readout the unit is working properly Ensure the boat is in water greater than 2 but less than the depth capability of the unit and the transducer is fully submerged Remember the sonar signal cannot pass through air If the unit is working properly grad
