Battery pack
The battery pack of the GEONAV allows
you to use it as a portable unit. Use 4
alkaline cells or rechargeable batteries,
AA size (if possible, high-capacity batter-
ies, 2000mAh or higher).
Make sure that the unit is off and dry
when replacing the batteries.
To access the battery slot, loosen the lock-
ing screws by means of a coin or the round
side of a key, as shown in the figure.
Extract the battery pack, flip it over and
loosen the cover locking screws.
Remove the cover and insert the batter-
ies according to the polarity indicated.
Make sure that the "Battery type" selec-
tor located in the cartridge slot is posi-
tioned correctly, according to the type
of battery used ("Rechargeable" position,
for rechargeable batteries; "Alkaline" po-
sition, for alkaline batteries).
To change the selection, move the small
lever by means of a sharp object.
WARNING: All the units are supplied with the battery
selector set to "Alkaline". When using alkaline batter-
ies, the selector has to be set to "Alkaline". You are
warned NEVER to use alkaline-type batteries if the
selector is set to "Rechargeable". In this case the unit
can be seriously damaged. This kind of damage is not
covered by the warranty. When using rechargeable

batteries, the selector can be set either to
"Rechargeable" or to "Alkaline". However
the battery charge function is active on con-
dition that the selector is set to "Recharge-
able". The misplacement of the selector may
cause the batteries to break, the corrosive
liquid to leak out and, consequently, the unit
to be damaged. This kind of damage is not
covered by the warranty.
Check that the contacts in the battery
pack are clean and dry.
Before reassembling the battery pack,
make sure that the rubber gasket in the
slot and the rubber O-rings tightening
the locking screws are clean and in the
correct position.
The misplacement of the gaskets, together with any presence
of sand, saline residues or dirt, may be detrimental to the
tightness of the battery slot since it allows moisture to pen-
etrate into the unit and damage the electronic inner compo-
nents. This kind of damage is not covered by the warranty.
Reassemble the battery pack carrying out the disassembly op-
erations in reverse order.
Should the battery pack not fit, or fit with difficulty in its
seat, check that the CompactFlash™ is correctly inserted.
The partial extraction of the CompactFlash™ blocks the in-
sertion of the battery pack.
The unit can be powered by the batteries only or connected to
an external power supply. When the unit is powered by the
power supply cable, the inner batteries - if they are of re-
chargeable type - are fully recharged, after which the inner
battery charger is automatically disabled and the batteries dis-
connected in order to keep their charge.
