Acoustical noise-emission values
8
Ÿ
Average sound-pressure levels:
– 49 dBA idle
– 50 dBA operating
Ÿ
Declared (upper limit) sound power levels:
– 6.4 bels idle
– 6.5 bels operating
6 Under typical maximum configurations, the heat output will be substantially below the theoretical maximum.
7 Power consumption and heat output vary depending on the number and type of optional features installed and the
power-management optional features in use.
8 These levels were measured in controlled acoustical environments according to ISO 7779, and are reported in accordance with
ISO 9296. The declared sound power levels indicate an upper limit, below which a large portion of machines operate. Sound
pressure levels in your location might exceed the average 1-meter values stated because of room reflections and other nearby
noise.
