Upon entering diagnostic mode, a menu of available tests appears. See Figure
4.3. The soft buttons are labeled by the bottom line of the display. The
options are "A Burn-in Test", or "B Test Forever."
NOTE: The option labeled "Burning Test" on the bottom line of the display
refers to the Burn-in test, so called because it's used at the factory to
perform a general quality test of all the major components of the unit.
These tests are done multiple times to make sure the unit will perform
properly with extended use.
Figure 4.3 - Diagnostic Test Menu
Performing the Burn-in test on newly shipped units is recommended for a
general test. If a specific problem has occurred with a particular unit,
select the appropriate test(s) from the normal diagnostics menu. If repairs
or replacement of parts are necessary, to run the Burn-in test one or more
times when you've finished the repairs.

drive.
