should only be serviced by qualified service personnel.
Warning: Before servicing the equipment plug your safety strap
into a proper grounding outlet. Failure to do so could damage the
equipment.

the cables from the workstation.
Caution: To protect the internal circuitry from damage, unplug the
AC power cord and then momentarily press the power switch ON to
drain the power supply capacitance.
