If there is only one test for a device, the program begins testing immediately. If there
is more than one test for the device, you see a submenu.
If you selected to run the tests more than once, you do not see a submenu. The
program immediately begins executing all the tests that do not destroy data.
When the test is completed, you see the Execute menu or the test submenu again.
You can select another test or exit the menu.
To exit system diagnostics, press -> to select Quit and press Enter. You return to
the operating system command prompt.
Resuming From an Error
If an error prevents a test from running, you see a Runtime Error information box. Follow
the instructions on the screen to solve the problem.
If an error occurs during a test, the test stops and an error message appears. Follow the
instructions on the screen to print the message or to continue without printing it.
For a complete list of the error messages the program may display, see the table at the end of
this chapter.
