2.1 INTRODUCTION
There is only one mechanical function required of the operator: to ensure that
power is applied. During routine computer operations, the operator should,
of course, note any malfunctions or problems and report them.
2.2 OPERATING AND PRELIMINARY DIAGNOSIS PROCEDURE
Due to the sophisticated design and special equipment required to repair the
FINCH, most repairs may only be effected at a properly equipped and staffed
depot service and repair facility. These repair facilities will be capable of
performing all warranty and routine repair activities.
Because there are no lamps for error or fault indication and no operator/drive
interaction is required, operating systems must contain sufficient error report-
ing information to allow the operator to make preliminary diagnosis of problems.
In other words, software must adequately inform the operator if any technical
difficulties arise. In multi-unit installation, logical and physical identifications
are necessary for the operator to identify a defective unit.
