Safety notes
V CAUTION!
● Do not install unsupported CPUs. For further information on
supported CPUs, see section "Basic information" on page 206.
● Circuit boards and soldered parts of internal options are exposed and
can be damaged by static electricity. Always discharge static build-up
(e.g. by touching a grounded object) before handling electrostatic-
sensitive devices (ESDs).
● Do not touch the circuitry on boards or soldered parts. Hold circuit
boards by their metallic areas or edges.
● When removing or installing the CPU, be careful not to touch or bend
the spring contacts on the CPU socket.
● Never touch the underside of the CPU. Even minor soiling such as
grease from the skin can impair the CPU’s operation or destroy the
CPU.
● Follow the safety instructions in chapter "Important information" on
page 33.
