ACCESS UNDER MOUNTING LOCATION

Follow these steps to deck mount the GPS receiver when routing the cable down through the mounting location:

1.Determine the best location, then test route the 20' (6 m) cable from the mounting location to the control head.

NOTE: Installation details may vary with unit configuration.

2.Mark the mounting location and drill a 3/4" (19 mm) hole for the cable and cable plug. Route the cable.

3.Cover the cable hole with the receiver. Make sure the receiver is flush on the surface and mark the two mounting holes with a pencil or punch.

4.Move the receiver to the side and drill two pilot holes using a 9/64" (3.5 mm) bit.

NOTE: Remember to caulk or seal screw holes and drilled holes as needed to protect your boat from water damage.

5.Align the GPS receiver screw holes over the pilot screw holes and attach with the #8 - 1 1/4" (32 mm) Phillips head screws. Hand tighten only!

NOTE: If the mounting surface is thin and made of a lighter material, a backing material may be needed below the mounting surface.

NO ACCESS UNDER MOUNTING LOCATION

Follow these steps to deck mount the GPS receiver in a situation where you must route the cable to the side because there is no space for a cable underneath the mounting location.

1.Determine the best location, then test route the cable from the mounting location to the control head.

NOTE: AS-EC10 10' extension cables are available from Humminbird® if your planned routing exceeds 20', (6 m). Maximum cable length, including extensions, should not exceed 50' (15 m).

2.Confirm the cable length is good and route the cable from the receiver to the control head. If holes are required to route the cable, they must be 3/4" (19 mm) to allow for the cable connector. Secure the NMEA pigtail with electrical tape.

NOTE: Remember to caulk or seal screw holes and drilled holes as needed to protect your boat from water damage.

3.The GPS receiver has two wire routing notches. Use the cable notch closest to the intended cable route.

4.With the cable routed, position the GPS receiver in the planned mounting location and mark the mounting holes with a pencil or punch.

5.Move the GPS receiver to the side and drill the two 9/64" (3.5 mm) pilot holes.

6.Align the GPS receiver's screw holes over the pilot screw holes and attach with the #8 - 1 1/4" (32 mm) Phillips head screws. Hand tighten only!
