INSTALLATION AND PRECAUTIONS
Precautions
Wherever possible, the power supply cable shield should be
connected to the boat’s ground plate.
The GEONAV is water resistant but not waterproof, therefore
it should not be immersed totally in water.
The cartridge slot cover, located on the plotter’s right-hand
side, should always be kept closed and opened only when
replacing cartridges. Make sure that the cartridge replacement
is carried out as the unit is perfectly dry and that no water
enters the unit.
Rear connectors, when not in use, should always be protected
by the appropriate rubber covers.
Cleaning
It is recommended the use of a non-alcoholic product to clean
the glass, since alcoholic products may damage the glass sur-
face or make it opaque.
Panel mounting
Locate the area where the GEONAV is to be installed, then
use the drilling template supplied with the plotter to properly
cut holes and sockets out of the instrument’s panel.
The neoprene adhesive gasket supplied must be applied to
the GEONAV rear side 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 panel. Do not exceed
tightening the screws, in order to avoid damaging the screw
seats.
