Installing the Fishfinder 400C

Installing the Fishfinder 400C on the Mounting Bracket To install the unit on the mounting bracket:

1.Align the slot on the back of the fishfinder with the long mounting knob, and slide the fishfinder into place. If necessary, adjust the long knob to spread the bracket arms apart. (Turn counter-clockwise to widen the bracket arms and clockwise to tighten.)

2.Adjust the fishfinder angle, and tighten the long mounting knob until snug.

3.Rotate the swivel mount bracket by twisting it left or right. The bracket clicks as you turn it. Select a good viewing angle, and then tighten all knobs.

4.Connect the power/data and transducer cables to the back of the fishfinder, making sure the locking rings are fully tightened on both connectors.
