There are several operational tests run at power up. The test
is displayed only if any of the tests fail. The results are
displayed to the right of the test as shown in Figure 12. If
you would like the test screen displayed regardless of
results, press any key while pressing the ON key at initial
power up. If any test fails, check the troubleshooting section
for possible correction. When displaying the tests as
described above, a stuck key will be indicated.
