Installation Overview; Control Head Installation; Gimbal Mounting The Control Head - Humminbird 1158c Combo Installation And Operation Manual

Installation Overview

Inside the boat there is often a channel or conduit used for other wiring, this can be used to
route cables. Be sure to route the cable as far as practical from the antenna cable of VHF radios
or tachometer cables to reduce the possibility of interference. The transducer and GPS receiver
cables should not be cut, and care should be used not to damage the cable insulation.
Basic installation tasks that you must perform include the following:
• Installing the control head (choose gimbal or in-dash mounting)
• Installing the transducer (choose the installation method that matches your transducer)
• Installing the GPS Receiver
• Testing the complete installation and locking the transducer position
