All tests are conducted according to ISO 7779 and declared according to ISO 9296 except 90% CPU. For this mode, the system
CPU was stressed at 90% utilization with no other peripheral device actively seeking. This test mode is not specified in ISO 7779,
but was measured using the same microphone distances and measurement techniques defined for the other reported operating
modes.
