4 Troubleshooting

4.1 Overview of troubleshooting

The LD6 uses a touch screen to access an embedded Windows XP operating system.
The system contains no user-serviceable parts.
The cover should not be removed except under the guidance of a VERIPOS engineer,
first ensuring that the unit is isolated from all AC and DC power supplies.
Problems experienced when using the LD6 system relate to antenna connectivity,
correction signal reception, configuration errors or relate to the GNSS satellite positioning
signal reception for inclusion in calculating a position solution.

Hardware

Hardware fault finding should be limited to checking the security of connectors and
checking supply voltage.
It is strongly recommended before detailed investigation is undertaken to first check
coaxial cable integrity and correct location of antennas.
