2.4.12 PRODUCTION TESTS
Normally, cleaning is not required; but for situations where dust
has accumulated on the faceplate display, a dry cloth can be used.
Units that are stored in a de-energized state should be
powered up once per year, for one hour continuously, to
avoid deterioration of electrolytic capacitors.
