VCCI Notice (Japan Only)
Most Dell devices 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 devices, expansion cards, printers, input/output (I/O)
devices, monitors, and so on, integrated into or connected to the device should match the electromagnetic environment classification (Class A or B) of the
device.
To determine which classification applies to your device, examine the regulatory labels/markings located on the bottom, side, or back panel of your device.
Once you have determined your device's VCCI classification, read the appropriate VCCI notice (see "VCCI Class A ITE Regulatory Mark" or "VCCI Class B ITE
Regulatory Mark").

This is a Class A product based on the standard of the Voluntary Control Council for Interference (VCCI) for information technology equipment. If this
