APEX™ SERIES CONTROL HEAD Installation Guide
6. 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
7. 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.
8. 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 outer
mounting screw locations using a pencil or center punch.
Make sure the bracket faces forward. The opening in the gimbal bracket arms must face the
rear of the control head. See the illustration Assembling the Control Head and Bracket for
more information.
2. Mark the four mounting screw locations using a pencil or center punch.
3. Set the gimbal bracket aside. Drill the four mounting screw holes using a 5/32" (4 mm) drill bit.
4. Cable Hole: Mark and drill a 1 1/4" (31.75 mm) hole 2" to 4" (50 to 100 mm) behind the bracket.
You will use this hole for routing the cables to the control head in another section.
5. Proceed to Traditional Mount or Overhead Mount.
Traditional Mount
1. Place the bracket on the mounting surface aligned with the drilled holes.
2. Fill the mounting holes with marine-grade silicone sealant.
3. Place one flat washer onto each #10 x 1" wood screw. Insert the four screws with washers into
the mounting holes and tighten them until they are secure (see the illustration Installing the
Gimbal Bracket). Hand tighten only!
4. Place the control head back onto the gimbal bracket (see Plan the Mounting Location for
details). Adjust the control head viewing angle as needed and tighten the gimbal knobs until
the assembly is secured. Hand-tighten only!
