Step #1 Attach module as shown with the lens facing towards the mounting arm. The module should swing freely from heel to toe to adjust for various lie angles. Step #2 Open bracket so it can fit around putter shaft then tighten mounting nut only enough to hold the unit in place so that it can adjusted for final position in next steps. Step #3 Slide the mounting bracket on the putter shaft until the module is hanging directly over center of the putter from your address position. Tighten slightly to hold in place. Step #4 VERY IMPORTANT! The module MUST BE square to the face in order to achieve proper telemetry readings. Look down from address and adjust the mounting arm that holds the module so that it is exactly parallel to the face top-line. Tighten the mounting nut to keep firmly in place. DO NOT OVER TIGHTEN. You're now ready to go. Step #5 Turn target upside down. With the base of the legs pointing up and away from the target, squeeze the legs so that they can fit into guide holes on one side of the two bottom brackets. Release so they lock into place. Repeat for the other side. Step #6 When set-up properly for use, this is how the equipment will look.
