8.8.2 Description of diagnostic tests
Single test, Conti(nuous) test
The single and conti(nuous) tests check the ROMs and RAMs for proper operation,
one time or continuous, respectively. After the test is completed, the results are indi-
cated as OK (normal operation) or NG (malfunction), to the right of the device
checked. For the single test, normal operation is restored after completion of the test.

up condition.
