NPB-40
This section discusses the tests used to verify performance following repairs or

NPB-40 cover. All tests except the battery charge and battery performance tests
must be performed as the last operation before the NPB-40 is returned to the user.
If the NPB-40 fails to perform as specified in any test, repairs must be made to
correct the problem before the NPB-40 is returned to the user.
