10. All low impedance test equipment (such as pulse generators, etc.) should be connected to CMOS
device inputs after power is applied to the CMOS circuitry. Similarly, such low impedance
equipment should be disconnected before power is turned off.
11. Replacement modules shipped separately from the factory will be packaged in a conductive material.
Any modules being transported from one area to another should be wrapped in a similar material
(aluminum foil may be used). Never use non-conductive material for packaging these modules.
