2.2 Fitting the optional external
GPS antenna
The Geosat is equipped with a built-in GPS
antenna and with a port for an optional
external antenna. The external antenna can
be useful in case of shielded windscreens.
The external antenna does not need power.
The magnetic base of the external GPS
antenna can be placed on any flat metallic
surface, with the antenna facing up. The
higher the GPS antenna is placed, the better
it will receive the signal.
To guarantee a good signal place the external
antenna on the bonnet or on the roof. The
cable is made of a tear-proof material so
that it does not break if it is accidentally
closed between the door and the body of the
vehicle. The antenna should not be covered
with shielding materials (e.g. metal). Do not
put the antenna in the boot or in the glove
box.
After positioning the antenna take its cable
inside the vehicle, passing it through the
passenger door seal and connect the end
plug into the Geosat.
2.3 Power connection
Whilst the Geosat is equipped with a built-in
Li-Io rechargeable battery, it is recommended
that you power the unit via the car cigarette
lighter / 12 V power socket during your
journey.
Geosat comes with the battery uncharged,
but the navigator can be used right away with
the car charger. The battery will require 4
hours charging to be fully charged.
Geosat can be fed with voltage between 10
and 35 V. The car charger cable provided in
the box should be used to power the Geosat
via the car cigarette/12 V power socket.
1. Plug the car charger cable into the Geosat.
2. Remove the cigarette lighter from its slot
or remove the 12 V power socket cover.
3. Insert the other end of the cable into the
socket.
Some vehicles are equipped with additional
12 V plugs.
The red LED on the plug confirms the correct
functioning of the power supply. If the LED is
off, check the connections or try again with
the vehicle engine on.
The battery recharges when the navigator
is fed with the power supply cable, either
if it is on or if it has been switched off with
the PAGE button. In this case, the keyboard
