1. Plan the Mounting Location
Start by locating a suitable, flat area of the dashboard for mounting. Consider the following to find the best
mounting location:
• Interference: The mounting location must provide adequate distance from electric motors or any
equipment that may cause electronic interference.
• Stability: The mounting area should be protected from waves, shock, vibration, and water.
• Depth: The mounting area should have a depth of 3 inches (7.62 cm) to allow space for the control
head and cables.
• Ventilation: The area beneath the mounting surface should be well-ventilated.
• Accessibility: The location should be easily accessible for all cables to reach the ports on the back of
the control head.
NOTE: If a cable is too short for your application, extension cables are available. For assistance, contact Humminbird
