Installation and Precautions

INSTALLATION AND PRECAUTIONS
To avoid electromagnetic interference, the GEONAV must be
positioned at least 0.35 meters away from magnetic compasses
or flux-gate sensors, such as those used on autopilots and
remote electronic compasses.
The GEONAV is totally waterproof (IPX7) and weatherproof. It
is essential that the battery pack on the unit's rear side is
firmly inserted and tightly screwed and that the battery pack
is removed only when the CompactFlash™ or batteries need
replacing. Always make sure that, during the replacement op-
erations, the unit is perfectly dry.
NOTE: Any damage caused by the presence of water inside the unit, due to the lack
or incorrect installation of the battery pack, is specifically excluded from the warranty.
Cleaning
It is recommended that you use a nonalcoholic product to clean
the glass, since alcoholic products may damage the glass surface
or make it opaque.
Installation
The GEONAV allows using either the built-in antenna for outdoor
installation or an external GPS antenna for indoor use.
NOTE: At start-up, the plotter will select the internal GPS by default.
• Internal GPS: For the best reception of satellites, mount your
unit in an open area to allow the built-in antenna to have
the best sky visibility. If the instrument is installed so as
to allow full horizon visibility, the best performance will
be ensured.
• External GPS: Instead of a built-in antenna, you can use an
external GPS. To connect the GEONAV to an external an-
tenna, use the optional NMEA data cable (see the C o nn e c -
t i o n s Section).
