4.4.3 Precautions for handling PC assemblies
Printed circuit assemblies contain CMOS integrated circuits, which can be damaged if the
assemblies are not properly handled. The following precautions must be observed when
working with the assemblies:
Do not install or remove the printed circuit assemblies while power is applied to the
units.
Keep electrical components and assemblies in their protective (conductive) carriers
or wrapping until ready for use.
Use the protective carrier as a glove when installing or removing printed circuit
assemblies.
Maintain contact with a grounded surface to prevent static discharge when
installing or removing printed circuit assemblies.
Note
CPU boards are switched off before shipping to preserve the board's battery. Before installing into
the GC, be sure to switch the CPU board on.
