1 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.
2 Declared Sound Power rounded to nearest tenth of a bel per ISO 9296 section 4.4.2
3 Declared Sound Pressure rounded to nearest dB per ISO 9296 section 4.4.3.
