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 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.
EN 55022 Compliance (Czech Republic Only)
This device belongs to Class B devices as described in EN 55022, unless it is specifically
stated that it is a Class A device on the specification label. The following applies to devices
in Class A of EN 55022 (radius of protection up to 30 meters). The user of the device is
obliged to take all steps necessary to remove sources of interference to telecommunication
or other devices.
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 Figures 1-1 and 1-2) located on the bottom or back panel of your
computer. Once you have determined your system’s VCCI classification, read the
appropriate VCCI notice.
Class A ITE
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.
