VCCI Notice (Japan Only)
Most Dell computer systems are classified by the Voluntary Control Council for Interference (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 regulatory labels/markings (see Figure
1, VCCI Class A ITE Regulatory Mark, and Figure 2, VCCI Class B ITE Regulatory Mark) located on the bottom or
back panel of your computer. Once you have determined your system's VCCI classification, read the appropriate VCCI
notice.
