6. Connecting the Transducer Cable
Connect the transducer cable to the transducer connector on the HDR 610.
NOTE: The connector is keyed to prevent reverse installation, so be careful not to force the plug
into the connector the wrong way.
7. Connecting to the Power Supply
Use the following information to connect your HDR 610 to an appropriate power supply:
• If your boat has an electrical system, there is probably a fuse panel in the console area
that can be used to attach the HDR 610 power cable.
• If a fuse terminal is available, use crimp-on type electrical connectors (not included) that
match the terminal on the fuse panel, and attach the black wire to ground, and the red
wire to 12 VDC power. You must use a 1-Amp fuse in the connection.
• 36" of power cable is included; you may shorten or lengthen this cable using
18-gauge, multi-strand copper wire.
CAUTION: Some boats have 24 or 36 Volt electrical systems. Make sure that your HDR 610 is
connected to a 12 VDC power supply. Use a voltage conditioner for variable inputs.
• If you must wire the HDR 610 directly to a battery, make sure that you install an in-line
fuse holder and a 1-Amp fuse (not included) for the protection of the unit. Humminbird®
is not responsible for over-voltage or over-current failures.

4. Installing the HDR 610
Once you have your mounting hole cut, perform the following steps:
1. Insert the HDR 610 from the front of the panel.
2. Install the "U" bracket and wingnut from the rear of the panel, and make sure that the face
of the HDR 610 is oriented correctly, so that the top of the unit is at the top of the hole.
NOTE: If the panel into which you are mounting the unit is greater than 1/4" thick, the "U"
bracket may appear too long. You may modify the "U" bracket by using pliers to break the legs
of the bracket at the score lines. Shorten the bracket in gradual stages to avoid making it too
short.
3. Tighten the wingnut to secure the installation.
5. Installing the Buzzer
Once the unit is mounted in the dash, secure the buzzer either to the metal bracket or to a nearby
wire bundle using the cable ties included.
