Installation

Before installing the Unit Switch, gather all the parts you will need, and make sure that the planned location of the Unit Switch will allow you to connect the two control heads to your transducer. Perform the procedures in the following sections to install the Unit Switch on your boat.

1. Locating the Unit Switch Mounting Position

There are two ways to find the mounting location, as follows:

Switch Panel: If your console already contains a switch panel with an available slot, slide the Unit Switch into the slot until it snaps into place. Then skip ahead to procedure two.

In-Dash:If your console does not have a switch panel or a pre-made mounting location, you will need to create one yourself.
