C. Temporary Revision Service
(1) Temporary revision service to this manual will be issued as
necessary to alert the customer of configuration differences and to
provide temporary instructions prior to the next scheduled revision.
Temporary revisions may also be issued as a result of a customer
request for incorporation of a service bulletin.
(2) A temporary revision will apply to one page block only and will be
keyed within the manual so that it will be filed adjacent to the
affected pages. Temporary revisions will not be revised. If
changes are required, the temporary revision will be superseded by
another one.
