requirements prior to the operation of the system. Activities or conditions within compartments
or areas outside the system shall be described as necessary. When it is impractical or illogical to

described to acquaint the operator with all equipment combinations that can be employed to effect
a given mode of operation.
3.6.5.1 Preoperational conditions and setup. Specific preoperational conditions presumed to be
in effect prior to system operation shall be established. A system readiness checkoff list of
