Regulatory Notices: Dell OptiPlex GX150 System User's Guide
Electromagnetic Interference (EMI) is any signal or emission, radiated in
free space or conducted along power or signal leads, that endangers the
functioning of a radio navigation or other safety service or seriously degrades,
obstructs, or repeatedly interrupts a licensed radio communications service.
Radio communications services include but are not limited to AM/FM commercial
broadcast, television, cellular services, radar, air-traffic control, pager, and
Personal Communication Services (PCS). These licensed services, along with
unintentional radiators such as digital devices, including computer systems,
contribute to the electromagnetic environment.
Electromagnetic Compatibility (EMC) is the ability of items of electronic
equipment to function properly together in the electronic environment. While
this computer system has been designed and determined to be compliant with
regulatory agency limits for EMI, there is no guarantee that interference will
not occur in a particular installation. If this equipment does cause
interference with radio communications services, which can be determined by
turning the equipment off and on, you are encouraged to try to correct the
interference by one or more of the following measures:
- Reorient the receiving antenna.
- Relocate the computer with respect to the receiver.
- Move the computer away from the receiver.
- Plug the computer into a different outlet so that the computer and the
receiver are on different branch circuits.
If necessary, consult a Dell Technical Support representative or an
experienced radio/television technician for additional suggestions.
Dell computer systems are designed, tested, and classified for their intended
electromagnetic environment. These electromagnetic environment classifications
generally refer to the following harmonized definitions:
- Class A is typically for business or industrial environments.
- Class B is typically for residential environments.
Information Technology Equipment (ITE), including peripherals, expansion
cards, printers, input/output (I/O) devices, monitors, and so on, that are
integrated into or connected to the system should match the electromagnetic
environment classification of the computer system.
A Notice About Shielded Signal Cables: Use only shielded cables for
connecting peripherals to any Dell device to reduce the possibility of
interference with radio communications services. Using shielded cables ensures
that you maintain the appropriate EMC classification for the intended
environment. For parallel printers, a cable is available from Dell. If you
prefer, you can order a cable from Dell on the World Wide Web at
accessories.us.dell.com/sna/segmenter.asp.
Most Dell computer systems are classified for Class B environments. However,
the inclusion of certain options can change the rating of some configurations to
Class A. To determine the electromagnetic classification for your system or
device, refer to the following sections specific for each regulatory agency.
Each section provides country-specific EMC/EMI or product safety
information.
Most Dell computer systems are classified by the Federal
Communications Commission (FCC) as Class B digital devices. To determine which
classification applies to your computer system, examine all FCC registration
labels located on the bottom or back panel of your computer, on card-mounting
brackets, and on the cards themselves. If any one of the labels carries a Class
A rating, your entire system is considered to be a Class A digital device. If
all labels carry an FCC Class B rating as distinguished by either an FCC ID
number or the FCC logo ( ), your system is considered to be a Class B
digital device.
Once you have determined your system's FCC classification, read the
appropriate FCC notice. Note that FCC regulations provide that changes or
modifications not expressly approved by Dell could void your authority to
operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to
the following two conditions:

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.
Certain configurations of Dell™ computers comply with the
requirements set forth by the Environmental Protection Agency (EPA) for
energy-efficient computers. If the front panel of your computer bears the ENERGY
STAR® Emblem, your original configuration complies with these
requirements and all ENERGY STAR® power management features of the
computer are enabled.
|
NOTE: Any Dell computer bearing the ENERGY STAR Emblem is
certified to comply with EPA ENERGY STAR requirements as configured when
shipped by Dell. Any changes you make to this configuration (such as
installing additional expansion cards or drives) may increase the
computer’s power consumption beyond the limits set by the EPA's ENERGY
STAR Computers program. |
The EPA's ENERGY STAR Computers program is a joint effort
between the EPA and computer manufacturers to reduce air pollution by promoting
energy-efficient computer products. The EPA estimates that use of ENERGY STAR
computer products can save computer users up to two billion dollars annually in
electricity costs. In turn, this reduction in electricity usage can reduce
emissions of carbon dioxide, the gas primarily responsible for the greenhouse
effect, and sulfur dioxide and nitrogen oxides, the primary causes of acid
rain.
You can also help reduce electricity usage and its side
effects by turning off your computer when it is not in use for extended periods
of time, particularly at night and on weekends.
On Class A systems, the following warning will appear near the
