INSTALLATION OVERVIEW

Before you start installation, we encourage you to read these instructions carefully in order to get

the full benefit from your HDR 610 Digital Depth Gauge. You will install your HDR 610

depthsounder first, then your transducer. When you are done with both of these installation tasks,

you should perform a final installation test before operating your HDR 610.

Please make sure that the following parts are included for your depthsounder:

• HDR 610 depthsounder

• "U" bracket and mounting hardware

• 2 cable ties.

Also, please make sure the following parts are included for your transducer:

• Transom mount or Puck transducer with 20' of cable

• Transducer mounting hardware kit.

In addition to the hardware supplied, you will need the following for installation and operation:

• Powered hand drill and various drill bits, including a 2 1/8" hole saw, if your boat does not

have an existing gauge hole

• Phillips-head and flat-head screwdrivers

• Ruler or measuring tape

• Pen or pencil

• 12 Volt power source (your boat's battery)

• Marine-grade silicone sealant (for sealing drilled holes)

• Two-part, slow-cure epoxy (for inside-the-hull transducer installation only).

NOTE: If you are wiring directly to the boat's battery, you will also need a 1 Amp fuse and a

fuse holder.
