4. Route and secure the cable by attaching the cable clamp to the transom;
drill one 9/64" diameter x 5/8" deep hole, then fill hole with marine-grade
silicone sealant, then attach the cable clamp using a #8 x 5/8" screw.
NOTE:
If there is excess cable that needs to be
gathered at one location (as shown in the
illustration), dress the cable routed from both
directions so that a single loop is left extending from
the storage location. Doubling the cable up from this
point, form the cable into a coil. Storing excess cable
using this method can reduce electronic interference
(see the illustration
Storing Excess Cable
).
5. Connecting the Cable
If you unplugged the transducer cable at the beginning of this procedure, plug it
back into the depth sounder.
NOTE:
The connector is keyed to prevent reverse installation, so be careful not to
force the plug into the connector the wrong way.
6. Test and Finish the Installation
Once you have installed both the HDR 650 and the transom transducer, and have
routed all the cables, you must perform a final test before locking the transducer
in place. Testing should be performed with the boat in the water although you
can initially confirm basic operation with the boat out of the water.
1. Turn on the power source to power up the HDR. If the unit does not power
up, make sure that the connector holder is fully seated in the receptacle
and that power is available.
2. If all connections are correct and power is available, the Humminbird®
control head will enter Normal operation.
3. If the digital depth readout displays on the screen, the unit is working
properly. Make sure that the boat is in water greater than 2' but less than
the depth capability of the unit, and that the transducer is fully submerged,
since the sonar signal cannot pass through air.
