Battery Disposal
Your computer system uses a lithium battery. The lithium battery is a long-life battery, and it is very possible that you will never need to replace it.
However, should you need to replace it, refer to the section about replacing the battery in your Dell system documentation for instructions.
Do not dispose of the battery along with household waste. Contact your local waste disposal agency for the address of the nearest battery deposit
site.

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.
