Installation Overview
1
| Plan the Mounting Location
1. Install the gimbal knobs into each side of the control head. Tighten the knobs just enough so
you can slide the control head into the gimbal bracket arms.
2. Place the assembled control head in various locations to determine the best mounting location
with the following requirements:
∆ a stable, protected surface to protect the control head from excessive wave shock, vibration,
and water
∆ sufficient space for the control head tilt range
∆ visibility during operation, as well as easy installation and removal
∆ access above and below the mounting surface to pass the cables through to the control
head
∆ space for the 1" (25 mm) cable hole, under the bracket or 2" to 4" (50 to 100 mm) behind
the chosen mounting location
3. Test route all cables (transducer, power, accessory, Ethernet) to the control head mounting
location.
4. After you have selected the mounting location, loosen the gimbal knobs and remove the control
head from the gimbal bracket.

| Install the Gimbal Bracket
1. Place the gimbal bracket in the chosen position on the mounting surface. Mark the four
mounting screw locations using a pencil or center punch.
2. Set the gimbal bracket aside and drill the four mounting screw holes using a 9/64" (3.5 mm)
drill bit.
3. To run the cables through a hole under the bracket, mark and drill a 1" (25 mm) hole, centered
between the four mounting holes. Press the grommet into place on the hole. Proceed to
Connect the Control Head to Power. You will complete the bracket installation (steps 4 and 5)
after you route the cables to the control head.
