| Assemble the Cable Tray
The cable tray is an important part of the control head installation. It secures the cables and protects
them from potential damage.
1. Use a Phillips head screwdriver to remove the screws from the bottom of the cable tray.
2. Hold the cable tray together and turn it over, so the Humminbird logo is facing up. Lift the
cover and set it aside.
3. See the illustration Locating the Cable Tray Slots. Insert each cable connector into the correct
slots in the tray.
Each slot is shaped specifically for each connector, and insertion should be easy. Route the
cables using the grooves in the tray.
Inserting the Cable Connectors into the Cable Tray
CAUTION! It is important to place the connectors into the correct slots and right side up. See
the illustration Locating the Cable Tray Slots for details.
4. Place the cover onto the tray. Hold the tray together and turn it over.
If the cable tray arms fall out, see the illustration Assembling the Cable Tray to put them back
in place.
5. Install the screws in the holes on the bottom of the tray. Hand tighten only. See the illustration
Removing the Screws to replace the screws. Hand tighten only.
6. Turn over the cable tray so the Humminbird logo is facing up.
Confirm the cables hang straight, and untwist them if necessary.
7. Line up the slots on the cable tray with the matching ports on the back of the control head.
Line up the cable tray pins with the holes on the control head (see the illustration Locating the
Cable Tray Slots).
With the Humminbird logo facing up, plug the cable tray into the back of the control head. The
cable tray clasps should click into place. See the illustration Connecting the Cable Tray to the
Control Head.
