T
o manually create a mounting location
:
1
. Locate a suitable, flat area of the dash to mount the Unit Switch. The switch requires a depth of at least 1.5 inches
(38.1 millimeters). Make sure that it will be positioned within 5 feet of one control head and within 20 feet of the
other control head, and that the transducer cable will reach to the planned location of the Unit Switch. 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 Control Heads to the Switch and the Transducer
If your control head is already installed, 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.
CAUTION! Do not cut or shorten the transducer cable, 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.com or call 1-800-633-1468 for more information.
To connect the transducer to the Unit Switch:
1. Access your Transducer cable and insert the Transducer cable connector into the Unit Switch connector until you
hear it click into place. Refer to the Connecting the Control Heads to the Switch and the Transducer
illustration on the following page for guidance.
To connect the control heads to the Unit Switch:
1. Insert the cable connectors from the Unit Switch through the T2 slots (transducer slots) on the connector holders.
Then reattach the connector holders, if necessary.
CAUTION: The slot for the connector is keyed to prevent reversed installation, so do not force the connector into the holder.
See your control head installation guide for additional information.
700 SERIES™ NOTE: If you are installing the Speed Sensor accessory (optional), insert the Sonar/Speed Y-Cable connector
into the T2 slot on the connector holder. Then, connect the transducer connector and speed sensor connector to the
corresponding connectors on the Y-Cable. The Y-Cable requires a separate purchase. Contact our Customer Resource Center
for details at 1-800-633-1468 or visit our Web site at humminbird.com.
