Installation and Precautions
INSTALLATION AND PRECAUTIONS
When installed on a boat, in order to avoid electromagnetic
interference, the GEONAV unit must be positioned at least
0.35 m away from a magnetic compass or a flux-gate sensor,
such as those used on autopilots and remote electronic
compasses.
The GEONAV is water resistant, but not waterproof. It is
essential that the rubber cover on the lower side of the unit is
firmly inserted in the cartridge slot; the rubber cover should
be removed only when the Nav-Chart™ has to be inserted or
replaced and, in this case, the unit must be perfectly dry. To
avoid continuous exposure to water, a protective cover is
supplied with the GEONAV: the cover should always be used
when the unit is turned off, in order to protect the unit from
direct sunlight and water.
For best satellites reception, mount your unit outside in an
open area to allow the best sky visibility to the built-in
antenna located on the upper side of the instrument. If the
instrument is installed so as to permit full horizon visibility,
the best performance will be ensured.
Panel mounting
A drilling template is supplied with the plotter to properly
locate holes and areas that have to be cut out of the
instrument panel.
A neoprene adhesive gasket is supplied with the unit and
must be applied to the rear of the plotter to avoid moisture
penetration and to reduce vibrations.
Mounting screws must be 4 mm in diameter and maximum 5
mm in length, plus the thickness of the instrument panel.
