Handling your board safely
Anti-static handling
The SBC and other circuit boards fitted inside the PEGASUS ICE contain CMOS
devices. These could be damaged in the event of static electricity being discharged
through them. Please observe anti-static precautions at all times when handling circuit
boards. This includes storing boards in appropriate anti-static packaging and wearing a
wrist strap when handling them.
Packaging
Should a board need to be returned to Arcom, please ensure that it is adequately
packed, preferably in the original packing material.
