Plan the Mounting Location
1. Place 1 rubber washer onto each gimbal knob.
2. Install the gimbal knobs (with washers) into each side of the control head. Tighten the knobs just enough so you can slide the control
head into the gimbal bracket arms.

NOTE: If you prefer to mount the control head overhead, flip the bracket to the top of the control head. The opening in the gimbal bracket arms
must face the rear of the control head.
3. Place the assembled control head in various locations to determine the best mounting location with the following requirements:
Δ a stable, protected surface to protect the control head from excessive wave shock, vibration, and water
Δ sufficient space for the control head tilt range
Δ visibility during operation, as well as easy installation and removal
Δ access above and below the mounting surface to pass the cables through to the control head
Δ space for the 1" (25 mm) cable hole located 2" to 4" (50 to 100 mm) behind the chosen mounting location
4. Test route all cables (transducer, power, Ethernet, accessories) to the control head mounting location. Leave enough cable length for
installing the cable tray and for the control head tilt range.
5. After you have selected the mounting location, loosen the gimbal knobs and remove the control head from the gimbal bracket.
