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 and Figure 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.

This is a Class A product based on the standard of the Voluntary Control Council for Interference (VCCI) for information technology equipment. If
this equipment is used in a domestic environment, radio disturbance may arise. When such trouble occurs, the user may be required to take
corrective actions.

according to the instruction manual.
