Warnings and Safety
a
STATIC ELECTRICITY
The Instrument and if available, its sensor unit contain CMOS devices and when
serviced, care must be taken to prevent damage due to static electricity. This is very
important to ensure long term reliability of the unit.
a
INSIDE THE INSTRUMENT (MAINTENANCE)
Under normal circumstances, there is no need to remove any of the printed circuit board
covers inside the Instrument, except for battery maintenance/replacement.
In any case, only trained personnel should remove these covers since power enters
directly into the Instrument and can be dangerous. Moreover untrained access may lead
to serious damage to the Instrument, as well as may void the warranty.
Especially the Lid cover should never be removed without first contacting to GeoSIG or
your local representative.
Before removing any of the covers, always:
1. Flip the main switch to "OFF"
2. Disconnect power supply from the POWER connector
3. Disconnect the main battery
4. Make sure that the green Active Charge “AC” LED indicator is OFF

In order to prevent data loss, you should be aware of that when a memory card, memory
