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 indicated 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. When the [MENU] key is pressed in the continuous test,
the equipment goes into start up condition.
