Most Dell computer systems are classified by the Voluntary Control Council for Inter-
ference (VCCI) as Class B information technology equipment (ITE). However, the
inclusion of certain options can change the rating of some configurations to Class A.
ITE, including peripherals, expansion cards, printers, input/output (I/O) devices,
monitors, and so on, integrated into or connected to the system, should match the
electromagnetic environment classification (Class A or B) of the computer system.
To determine which classification applies to your computer system, examine the regu-
latory labels/markings (see Figures 1 and 2) located on the bottom or back panel of
your computer. Once you have determined your system’s VCCI classification, read the
appropriate VCCI notice.
