8. Do not spray chemical on or near this instrument or any of its assemblies.
9. Electrostatically Sensitive (ES) Devices Some semiconductor (solid state) devices can be damaged easily
by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices.
Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor
"chip" components. The following techniques should be used to help reduce the incidence of component
damage caused by static electricity:
a) Immediately before handling any semiconductor-equipped assembly, drain off any electrostatic charge
on your body by touching a known earth ground. Wear a commercially available high impedance
discharging wrist strap device.
b) After removing an electrical assembly equipped with ES devices, place the assembly on a static
dissipative surface such as a 3M No 8210 table mat, to prevent electrostatic charge buildup or
exposure of the assembly.
c) Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES
devices.
d) Do not remove a replacement ES device from its protective package until immediately before you are
ready to install it (Most replacement ES devices are packaged with leads electrically shorted together
by conductive foam, aluminium foil or comparable conductive material).
e) Immediately before removing the protective material from the leads of a replacement ES device, touch
the protective material to the chassis or circuit assembly into which the device will be installed.
CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety
precautions.
f) Minimize bodily motions when handling unpacked replacement ES devices (Otherwise harmless
motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted
floor can generate static electricity sufficient to damage an ES device).
