Connecting The Cable; Test And Finish The Installation - Humminbird HDR 610 Installation And Operation Manual

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

Insert the transducer cable into the appropriate terminal slot. The cable connectors are
labeled, and there are corresponding labels on the cable holder on the rear of the
control head. The slots are keyed to prevent reversed installation, so be careful not to
force the connector into the holder. Refer to your manual and/or control head
installation guide for the correct procedure for installing the cable connectors to the
control head.
1. Plug the other end of the transducer cable back into the control head connection
holder.
Your control head is now ready for operation.

6. Test and Finish the Installation

Once you have installed both the control head 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. Press POWER once to turn the control head on. 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 bottom is visible on-screen with a digital depth readout, 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.
NOTE: The transducer must be submerged in water for reliable transducer detection.
4. If the unit is working properly, gradually increase the boat speed to test high-
speed performance. If the unit functions well at low speeds, but begins to skip or
miss the bottom at higher speeds, the transducer requires adjustment.
