V CAUTION!
– CPUs are modules which are extremely sensitive to electro-static
discharges and therefore must always be handled with care. After a
CPU has been removed from its protective sleeve or from its socket,
place it with its smooth side down on a non-conducting, antistatic
surface. Never push a CPU over a surface.
