Customer service
Malfunctions can sometimes have very trivial
causes, but at times can also be of quite a
complex nature and call for an in-depth analysis.
Basic hints
• The regular running of the Windows
®
programs “Defrag” and “Scandisk” can
remove sources of error and increase
system performance.
Error handling and tips
Start with a careful visual check of all cable
links. If the LCD’s are not working, make sure
that the power is reaching the computer and
all peripherals.
• Check that the USB ports are active and
correctly configured and that there are
no resource conflicts with other devices.
Please refer to your PC user manual on
this point.
