The Transducer Switch comes with all the necessary hardware to allow you to connect your control head to two transducers. The transducers may be the same type of transducer with different mounting locations, or you can maximize your unit’s performance by using two different transducers. The switch is intended for installation on the console, and will work well on almost any boat.

Supplies: In addition to the hardware supplied with your Transducer Switch, you will need a hand drill with various

size bits, a Phillips screwdriver, an adjustable wrench, and a 3 amp fuse.

Installation

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

1. Locating the Transducer 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 Transducer Switch into the designated 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.

o manually create a mounting location

. Locate a suitable, flat area of the dash to mount the Transducer Switch. The switch requires a depth of at least

1.5 inches (38.1 millimeters). Make sure that it will be positioned near your control head on the console of the boat, within reach of the cables for both transducers. Also, make sure you have access behind the panel in order to attach the cables.

2. Tape the template (included) over the desired in-dash mounting location.

3. At a location inside the dotted line on the template, drill a hole large enough to insert the blade of the reciprocating saw. Carefully begin cutting toward the dotted line, then follow the dotted line around the template. Remove the template when finished.

4. Insert the end of the switch through the hole until it snaps securely in place.

2. Connecting the Transducers and the Control Head to the Switch

To connect your Transducer Switch to your control head, you may have to remove the control head from the Quick Disconnect Mounting Bracket and temporarily disassemble the connector holder.

NOTE: Your connector holder hardware may be different than the illustration, depending on your Humminbird® model. See your control head installation guide for details.

Inserting the Cable Connector

CAUTION! Do not cut or shorten the transducer cables, and try not to damage the cable insulation. Route the cable as far as possible from any VHF radio antenna cables or tachometer cables to reduce the possibility of interference. If the cable is too short, extension cables are available to extend the transducer cable up to a total of 50 feet. For assistance, contact the Customer Resource Center at humminbird.comor call 1-800-633-1468 for more information.

To connect the transducers to the Transducer Switch:

1. Access your transducer cables and insert each transducer cable connector into a Transducer Switch connector until you hear it click into place. Refer to the illustration for guidance.
