Installing

CAUTION: The alignment tab on the sensor must be facing forward and parallel to
the centerline of the boat/vehicle for accurate compass readings.

CAUTION: Be sure to use the correct parts for your installation. Do not use the
flush mount parts (gasket, part B) to mount the receiver on a pole. Using the
wrong parts may allow water to leak into the unit.

CAUTION: If you use a thread locker, use teflon pipe thread tape. Do not use a
liquid thread locker as it may weaken the plastic, causing it to swell and crack.

IMPORTANT: Plan the cable route between the sensor and the display and/or
network before beginning the installation.

Pole or Rail Mount

The nut assembly supplied has standard marine 1"-14 threads that can be
screwed to a standard marine antenna mount, extension pole, or rail-mount
bracket. Before beginning the installation, plan for securing the pole/rail bracket to
the selected mounting surface and purchase all the necessary hardware. It may
be helpful to fasten the pole/rail bracket in place before proceeding.
1. Remove the label from the sensor unit’s socket (see Figure 2). Fasten the mount

base (part C) to the sensor unit (part A) with the two machine screws and lock
washers supplied. The torque for the screws is 1.35Nm.
