ACOUSTIC NOISE EMISSION INFORMATION
OPTIPLEX XE DT
The Declared Noise Emission in accordance with ISO 9296 for the Dell OptiPlex XE DT is as follows:
The Declared A-weighted Sound Pressure Level in decibels (re 2x10
-5
Pa), at Operator, Bystander, and Desk Side Positions are
measured in accordance with ISO 7779 7.6.1, 7.6.2, and C.15.2 and declared in accordance with ISO 9296 for this product is as

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.
