| Install the Cable Tray
The cable tray secures the cables and protects them from potential damage.
1. Route the cables to the control head.
CAUTION! Do NOT mount the cables where the connectors could be submerged in water or
flooded. If cables are installed in a splash-prone area, it may be helpful to apply dielectric
grease to the inside of the connectors to prevent corrosion. Dielectric grease can be
purchased separately from a general hardware or automotive store.
2. Use a Phillips head screwdriver to remove the screws from the bottom of the cable tray.
3. Hold the cable tray together and turn it over, so the Humminbird logo is facing up. Lift the cover and
set it aside.
4. 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.
5. 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.
6. Install the screws in the holes on the bottom of the tray. Hand-tighten only! See the illustration
Removing the Screws from the Cable Tray to replace the screws.
7. Turn over the cable tray so the Humminbird logo is facing up. Confirm the cables hang straight, and
untwist them if necessary.
8. 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.
9. Pull carefully on the cable tray to confirm the installation is secure. Make sure both clasps clicked
into place in step 8.
10. Your control head is ready for operation. See the Operations Summary Guide to get started.
