1.1 Antenna Units

1.1.1 GPS antenna unit

Install the GPS antenna unit referring to the drawing on page D-5 or D-6 at the back of this manual. When selecting a mounting location for the antenna, keep in mind the following points.

•Select a location out of the radar beam. The radar beam will obstruct or prevent reception of the GPS satellite signal.

•There should be no interfering object within the line-of-sight to the satellites. Objects within line-of-sight to a satellite, for example, a mast, may block reception or prolong acquisition time.

•Mount the antenna unit as high as possible to keep it free of interfering objects and water spray, which can interrupt reception of GPS satellite signal if the water freezes.
