ThinkCentre User Guide

Important safety information
CAUTION:
Before using this manual, be sure to read and understand all the related safety information for this
product. Refer to the information in this section and the safety information in the ThinkCentre Safety
and Warranty Guide that you received with this product. Reading and understanding this safety
information reduces the risk of personal injury and damage to your product.
If you no longer have a copy of the ThinkCentre Safety and Warranty Guide, you can obtain a Portable
Document Format (PDF) version from the Lenovo® Support Web site at http://www.lenovo.com/support. The
Lenovo Support Web site also provides the ThinkCentre Safety and Warranty Guide and this ThinkCentre
User Guide in additional languages.

Service and upgrades
Do not attempt to service a product yourself unless instructed to do so by the Customer Support Center or
your documentation. Only use a Service Provider who is approved to repair your particular product.
Note: Some computer parts can be upgraded or replaced by the customer. Upgrades typically are
referred to as options. Replacement parts approved for customer installation are referred to as Customer
Replaceable Units, or CRUs. Lenovo provides documentation with instructions when it is appropriate for
customers to install options or replace CRUs. You must closely follow all instructions when installing or
replacing parts. The Off state of a power indicator does not necessarily mean that voltage levels inside a
product are zero. Before you remove the covers from a product equipped with a power cord, always make
sure that the power is turned off and that the product is unplugged from any power source. For more
information on CRUs, refer to Chapter 5 “Installing or replacing hardware” on page 29. If you have any
questions or concerns, contact the Customer Support Center.
Although there are no moving parts in your computer after the power cord has been disconnected, the
following warnings are required for your safety.
CAUTION:

Hazardous moving parts. Keep fingers and other body parts away.
CAUTION:
Before replacing any CRUs, turn off the computer and wait three to five minutes to let the computer
cool before opening the cover.

Static electricity prevention
Static electricity, although harmless to you, can seriously damage computer components and options.
Improper handling of static-sensitive parts can cause damage to the part. When you unpack an option
© Copyright Lenovo 2011, 2012

or CRU, do not open the static-protective package containing the part until the instructions direct you
to install it.
When you handle options or CRUs, or perform any work inside the computer, take the following precautions
to avoid static-electricity damage:
• Limit your movement. Movement can cause static electricity to build up around you.
• Always handle components carefully. Handle adapters, memory modules, and other circuit boards by the
edges. Never touch exposed circuitry.
• Prevent others from touching components.
• When you install a static-sensitive option or CRU, touch the static-protective package containing the
part to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two
seconds. This reduces static electricity in the package and your body.
• When possible, remove the static-sensitive part from the static-protective packaging and install the part
without setting it down. When this is not possible, place the static-protective packaging on a smooth,
level surface and place the part on it.
• Do not place the part on the computer cover or other metal surface.

Power cords and power adapters
Use only the power cords and power adapters supplied by the product manufacturer.
The power cords shall be safety approved. For Germany, it shall be H05VV-F, 3G, 0.75 mm2, or better. For
other countries, the suitable types shall be used accordingly.
Never wrap a power cord around a power adapter or other object. Doing so can stress the cord in ways that
can cause the cord to fray, crack, or crimp. This can present a safety hazard.
Always route power cords so that they will not be walked on, tripped over, or pinched by objects.
Protect power cord and power adapters from liquids. For instance, do not leave your power cord or power
adapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers. Liquids can cause a
short circuit, particularly if the power cord or power adapter has been stressed by misuse. Liquids also can
cause gradual corrosion of power cord terminals and/or the connector terminals on a power adapter,
which can eventually result in overheating.
Always connect power cords and signal cables in the correct order and ensure that all power cord
connectors are securely and completely plugged into receptacles.
Do not use any power adapter that shows corrosion at the ac input pins or shows signs of overheating (such
as deformed plastic) at the ac input or anywhere on the power adapter.
Do not use any power cords where the electrical contacts on either end show signs of corrosion or
overheating or where the power cord appears to have been damaged in any way.

Extension cords and related devices
Ensure that extension cords, surge protectors, uninterruptible power supplies, and power strips that you use
are rated to handle the electrical requirements of the product. Never overload these devices. If power strips
are used, the load should not exceed the power strip input rating. Consult an electrician for more information
if you have questions about power loads, power requirements, and input ratings.

ThinkCentre User Guide

Plugs and outlets
If a receptacle (power outlet) that you intend to use with your computer equipment appears to be damaged
or corroded, do not use the outlet until it is replaced by a qualified electrician.
Do not bend or modify the plug. If the plug is damaged, contact the manufacturer to obtain a replacement.
Do not share an electrical outlet with other home or commercial appliances that draw large amounts of
electricity; otherwise, unstable voltage might damage your computer, data, or attached devices.
Some products are equipped with a three-pronged plug. This plug fits only into a grounded electrical outlet.
This is a safety feature. Do not defeat this safety feature by trying to insert it into a non-grounded outlet. If
you cannot insert the plug into the outlet, contact an electrician for an approved outlet adapter or to replace
the outlet with one that enables this safety feature. Never overload an electrical outlet. The overall system
load should not exceed 80 percent of the branch circuit rating. Consult an electrician for more information
if you have questions about power loads and branch circuit ratings.
Be sure that the power outlet you are using is properly wired, easily accessible, and located close to the
equipment. Do not fully extend power cords in a way that will stress the cords.
Be sure that the power outlet provides the correct voltage and current for the product you are installing.
Carefully connect and disconnect the equipment from the electrical outlet.

External devices
Do not connect or disconnect any external device cables other than Universal Serial Bus (USB) and 1394
cables while the computer power is on; otherwise, you might damage your computer. To avoid possible
damage to attached devices, wait at least five seconds after the computer is shut down to disconnect
external devices.

Heat and product ventilation
Computers, power adapters, and many accessories can generate heat when turned on and when batteries
are charging. Always follow these basic precautions:
• Do not leave your computer, power adapter, or accessories in contact with your lap or any part of your
body for an extended period when the products are functioning or when the battery is charging. Your
computer, power adapter, and many accessories produce some heat during normal operation. Extended
contact with the body could cause discomfort or, potentially, a skin burn.
• Do not charge the battery or operate your computer, power adapter, or accessories near flammable
materials or in explosive environments.
• Ventilation slots, fans, and heat sinks are provided with the product for safety, comfort, and reliable
operation. These features might inadvertently become blocked by placing the product on a bed, sofa,
carpet, or other flexible surface. Never block, cover, or disable these features.
Inspect your desktop computer for dust accumulation at least once every three months. Before inspecting
your computer, turn off the power and unplug the computer's power cord from the electrical outlet; then
remove any dust from vents and perforations in the bezel. If you notice external dust accumulation, then
examine and remove dust from the inside of the computer including heat sink inlet fins, power supply vents,
and fans. Always turn off and unplug the computer before opening the cover. If possible, avoid operating
your computer within two feet of high-traffic areas. If you must operate your computer in or near a high-traffic
area, inspect and, if necessary, clean your computer more frequently.

vii

For your safety and to maintain optimum computer performance, always follow these basic precautions
with your desktop computer:
• Keep the cover closed whenever the computer is plugged in.
• Regularly inspect the outside of the computer for dust accumulation.
• Remove dust from vents and any perforations in the bezel. More frequent cleanings might be required for
computers in dusty or high-traffic areas.
• Do not restrict or block any ventilation openings.
• Do not store or operate your computer inside furniture, as this might increase the risk of overheating.
• Airflow temperatures into the computer should not exceed 35°C (95°F).
• Do not install air filtration devices. They may interfere with proper cooling.

Operating environment
The optimal environment in which to use your computer is 10°C-35°C (50°F-95°F) with humidity ranging
between 35% and 80%. If your computer is stored or transported in temperatures less than 10°C (50°F),
allow the cold computer to rise slowly to an optimal operating temperature of 10°C-35°C (50°F-95°F) before
use. This process could take two hours in extreme conditions. Failure to allow your computer to rise to an
optimal operating temperature before use could result in irreparable damage to your computer.
If possible, place your computer in a well-ventilated and dry area without direct exposure to sunshine.
Keep electrical appliances such as an electric fan, radio, high-powered speakers, air conditioner, and
microwave oven away from your computer because the strong magnetic fields generated by these
appliances can damage the monitor and data on the hard disk drive.
Do not place any beverages on top of or beside the computer or other attached devices. If liquid is spilled on
or in the computer or an attached device, a short circuit or other damage might occur.
Do not eat or smoke over your keyboard. Particles that fall into your keyboard can cause damage.

Modem safety information
CAUTION:
To reduce the risk of fire, use only No. 26 AWG or larger (for example, No. 24 AWG) telecommunication
line cord listed by Underwriters Laboratories (UL) or certified by the Canadian Standards Association
(CSA).
To reduce the risk of fire, electrical shock, or injury when using telephone equipment, always follow basic
safety precautions, such as:
• Never install telephone wiring during a lightning storm.
• Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
• Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at
the network interface.
• Use caution when installing or modifying telephone lines.
• Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote
risk of electric shock from lightning.
• Do not use the telephone to report a gas leak in the vicinity of the leak.

Chapter 3. You and your computer
This chapter provides information about accessibility, comfort, and relocating your computer to other
countries or regions.

Accessibility and comfort
Good ergonomic practice is important to get the most from your personal computer and to avoid discomfort.
Arrange your workplace and the equipment you use to suit your individual needs and the kind of work
that you perform. In addition, use healthy work habits to maximize your performance and comfort while
using your computer.
The following topics provide information about arranging your work area, setting up your computer
equipment, and establishing healthy work habits:
Lenovo is committed to providing people with disabilities greater access to information and technology.
As a result, the following information provides ways to help users that have hearing, vision, and mobility
limitations get the most out of their computer experience.
Assistive technologies enable users to access information in the most appropriate way. Some of these
technologies are already provided in your operating system, others can be purchased through vendors, or
accessed through the World Wide Web:
http://www.lenovo.com/healthycomputing

Arranging your workspace
To get the most from your computer, arrange both the equipment you use and your work area to suit your
needs and the kind of work you do. Your comfort is of foremost importance, but light sources, air circulation,
and the location of electrical outlets can also affect the way you arrange your workspace.

Comfort
Although no single working position is ideal for everyone, here are a few guidelines to help you find a
position that suits you best.
Sitting in the same position for a long time can cause fatigue. The backrest and seat of your chair should
adjust independently and provide good support. The seat should have a curved front to relieve pressure on
the thighs. Adjust the seat so that your thighs are parallel to the floor and your feet are either flat on the
floor or on a footrest.
When using the keyboard, keep your forearms parallel to the floor and your wrists in a comfortable position.
Use a light touch on the keyboard and your hands and fingers relaxed. Change the angle of the keyboard
for maximum comfort by adjusting the position of the keyboard feet.

Adjust the monitor so the top of the screen is at, or slightly below, eye level. Place the monitor at a
comfortable viewing distance, usually 51 to 61 cm (20 to 24 inches), and position it so you can view it
without having to twist your body. Also, position other equipment you use regularly, such as the telephone or
a mouse, within easy reach.

Glare and lighting
Position the monitor to minimize glare and reflections from overhead lights, windows, and other light sources.
Reflected light from shiny surfaces can cause annoying reflections on your monitor screen. Place the
monitor at right angles to windows and other light sources, when possible. Reduce overhead lighting, if
necessary, by turning off lights or using lower wattage bulbs. If you install the monitor near a window, use
curtains or blinds to block the sunlight. You can adjust the brightness and contrast controls on the monitor
as the room lighting changes throughout the day.
Where it is impossible to avoid reflections or to adjust the lighting, an antiglare filter placed over the screen
might be helpful. However, these filters might affect the clarity of the image on the screen; try them only after
you have exhausted other methods of reducing glare.
Dust buildup compounds problems associated with glare. Remember to clean your monitor screen
periodically using a soft cloth as directed in your monitor documentation.

Air circulation
Your computer and monitor produce heat. The computer has a fan that pulls in fresh air and forces out hot
air. The monitor lets hot air escape through vents. Blocking the air vents can cause overheating, which might
result in a malfunction or damage. Place the computer and monitor so that nothing blocks the air vents;
usually, 51 mm (2 inches) of air space is sufficient. Also, make sure the vented air is not blowing on people.

Electrical outlets and cable lengths
The location of electrical outlets, the length of power cords and cables that connect to the monitor, printer,
and other devices might determine the final placement of your computer.
When arranging your workspace:
• Avoid the use of extension cords. When possible, plug the computer power cord directly into an electrical
outlet.
• Keep power cords and cables neatly routed away from walkways and other areas where they might
get kicked accidentally.
For more information about power cords, see “Power cords and power adapters” on page vi.

Moving your computer to another country or region
When you move your computer to another country or region, you must take local electrical standards into
consideration. This section provides information on the following:
•

“Voltage-selection switch” on page 23

•

“Replacement power cords” on page 23

Voltage-selection switch
Some computers are equipped with a voltage-selection switch located near the power-cord connection
point on the computer and some computers do not have a voltage-selection switch. Before you install
your computer or relocate your computer to another country or region, you must be certain that you have
matched your computer to the voltage available at your electrical outlet.
CAUTION:
You must know the voltage of the electrical connection (outlet) where your computer will be
connected. If you do not know the voltage, contact your local electric company or refer to official
Web sites or other literature for travelers to the country or region where you are located.
If your computer has a voltage-selection switch, you must set the switch to match the voltage available at
your electrical outlet. Setting the voltage-selection switch incorrectly will cause the computer to malfunction
and might cause permanent damage to the computer. Do not connect the computer to an electrical
outlet until you have verified that the voltage-selection switch setting matches the voltage available at the
electrical outlets.
If your computer does not have a voltage-selection switch, inspect the voltage-rating label on the bottom of
the computer and note the following:
• If the voltage-rating label shows a range of either “100-127 V” or “200-240 V,” you must ensure that the
voltage provided at the electrical outlet matches the voltage rating on the computer label. If it does
not match, do not attempt to connect the computer to the electrical outlet, unless an external device
such as a voltage-converting transformer is used.
• If the voltage-rating label shows a dual range of “100-127 V” and “200-240 V,” this signifies that the
computer is suitable for worldwide operation and the computer will automatically adjust to the voltage at
the electrical outlet regardless of the country or region where the computer is being connected.

Replacement power cords
If you relocate your computer to a country or region that uses an electrical outlet style different from the
type you are currently using, you will have to purchase either electrical plug adapters or new power cords.
You can order power cords directly from Lenovo.

Creating and using recovery media
You can use recovery media to restore the hard disk drive to the factory default state. Recovery media are
useful if you transfer the computer to another area, sell the computer, recycle the computer, or put the
computer in an operational state after all other methods of recovery have failed. As a precautionary measure,
it is important to create recovery media as early as possible.
Note: The recovery operations you can perform using recovery media vary depending on the operating
system from which the recovery media were created. The recovery media might contain a boot medium
and a data medium. Your Microsoft Windows license permits you to create only one data medium, so it is
important that you store the recovery media in a safe place after you have made them.

Creating recovery media
This section provides instructions on how to create recovery media on different operating systems.

Note: On the Windows 7 operating system, you can create recovery media using discs or external USB
storage devices. On the Windows Vista operating systems, you can create recovery media using only discs,
so this operation is also called “creating Product Recovery discs.”

to restore the contents of the hard disk drive to the factory default state. Also, you can use recovery media to
put the computer in an operational state after all other methods of hard disk drive recovery have failed.
Attention: When you use recovery media to restore the contents of the hard disk to the factory default state,
all the files currently on the hard disk drive will be deleted and replaced by the factory default files.
To use recovery media on the Windows 7 operating system or the Windows Vista operating system,
do the following:
1. Depending on the type of your recovery media, connect the boot medium (memory key or other USB
storage device) to the computer, or insert the boot disc into the optical drive.
2. Repeatedly press and release the F12 key when turning on the computer. When the Please select
boot device window opens, release the F12 key.
3. Select the desired startup device and press Enter. The restore process begins.
4. Follow the instructions on the screen to complete the operation.
Note: After restoring your computer hard disk drive to the factory default state, you might have to reinstall
device drivers for some devices. See “Reinstalling device drivers” on page 75.

Performing backup and recovery operations
The Rescue and Recovery program enables you to back up all your hard disk drive contents including the
operating system, data files, software programs, and personal settings. You can designate where the
Rescue and Recovery program stores the backup:
• In a protected area of your hard disk drive
• On the secondary hard disk drive if a secondary hard disk drive is installed in your computer
• On an attached external USB hard disk drive
• On a network drive
• On recordable discs (a recordable optical drive is required for this option)
After you have backed up the contents of the hard disk drive, you can restore the complete contents of the
hard disk drive, restore selected files only, or restore the Windows operating system and applications only
while keeping the other data on your hard disk drive.

Basics
Here are some basic points about keeping your computer functioning properly:
• Keep your computer in a clean, dry environment. Make sure it rests on a flat, steady surface.

ThinkCentre User Guide

• Do not place items on top of the monitor or cover any of the vents in the monitor or computer. These
vents provide airflow to keep your computer from overheating.
• Keep food and drinks away from all parts of your computer. Food particles and spills might make the
keyboard and mouse stick and unusable.
• Do not get the power switches or other controls wet. Moisture can damage these parts and cause an
electrical hazard.
• Always disconnect a power cord by grasping the plug, but not the cord.

Cleaning your computer
It is a good practice to clean your computer periodically to protect the surfaces and ensure trouble-free
operation.
CAUTION:
Be sure to turn off the computer and monitor power switches before cleaning the computer and
monitor screen.

Computer
Use only mild cleaning solutions and a damp cloth to clean the painted surfaces of the computer.

Keyboard
To clean your computer keyboard, do the following:
1. Apply some isopropyl rubbing alcohol to a soft, dust-free cloth.
2. Wipe each keytop surface with the cloth. Wipe the keys one by one; if you wipe several keys at a time,
the cloth may hook onto an adjacent key and possibly damage it. Make sure that no liquid drips onto
or between the keys.
3. To remove any crumbs or dust from beneath the keys, you can use a camera blower with a brush
or cool air from a hair dryer.
Note: Avoid spraying cleaner directly onto the display or the keyboard.

Optical mouse
This section provides instructions on how to clean an optical mouse.
An optical mouse uses a light-emitting diode (LED) and an optical sensor to navigate the pointer. If the
pointer on the screen does not move smoothly with the optical mouse, you might need to clean the mouse.
To clean an optical mouse, do the following:
1. Turn off your computer.
2. Disconnect the mouse cable from the computer.
3. Turn the mouse upside down to check the lens.
a. If there is a smudge on the lens, gently clean the area with a plain cotton-tipped swab.
b. If there is debris in the lens, gently blow the debris away from the area.
4. Check the surface on which you are using the mouse. If you have a very intricate picture or pattern
beneath the mouse, it may be difficult for the digital signal processor (DSP) to determine changes
in the mouse position.
5. Reconnect the mouse cable to the computer.
6. Turn your computer back on.

Chapter 9. Preventing problems

Display screen
Dust buildup compounds problems associated with glare. Remember to clean your monitor screen
periodically. See “Cleaning a flat-panel monitor surface” on page 88 or “Cleaning a glass-screen surface”
on page 88.
Cleaning a flat-panel monitor surface
If you have a flat-panel computer display that has a flexible film surface, do the following to clean the special
surface. Wipe it gently with a soft, dry cloth, or blow on the screen to remove grit and other loose particles.
Then moisten a cloth with LCD cleaner and wipe the screen surface.
Many computer supply stores carry the special cleaning fluids for displays. Use cleaning fluids developed for
LCD displays only. First apply the fluid to a lint-free, soft cloth, then clean the LCD display. Some computer
supply stores carry pre-moistened towelettes for LCD maintenance.
Cleaning a glass-screen surface
To clean a glass-screen surface, wipe it gently with a soft, dry cloth, or blow on the screen to remove grit and
other loose particles. Then use a soft cloth moistened with a nonabrasive liquid glass cleaner.

Good maintenance practices
By performing a few good maintenance practices, you can maintain good computer performance, protect
your data, and be prepared in case of a computer failure.
• Empty your recycle bin on a regular basis.
• Run the Windows Disk Defragmenter program occasionally to prevent performance problems caused by
an excessive number of fragmented files.
• Clean out your Inbox, Sent Items, and Deleted Items folders in your e-mail application on a regular basis.
• Make backup copies of critical data on removable media memory at regular intervals and store the
removable media in a safe location. The frequency of making backup copies depends on how critical the
data is to you or your business. Lenovo makes a number of removable-media storage devices available
as options, such as CD-RW drives and recordable DVD drives.
• Back up your entire hard disk drive on a regular basis.
• If you are using the Windows Vista operating system, use or schedule System Restore to take a system
snapshot periodically.
Note: Always take a snapshot before installing new device drivers, updating software, or installing
new software.
• Keep your computer software up-to-date. See “Keeping your computer current ” on page 85 for more
information.
• Keep a log book. Entries might include major software or hardware changes, device-driver updates,
intermittent problems and what you did to resolve them, and any minor issues you might have
experienced. A log book can help you or a Lenovo technician determine if a problem is related to change
in hardware, change in software, or some other action that might have taken place.
• Create Product Recovery discs. See “Creating and using recovery media” on page 69 for more information
about using Product Recovery discs to restore the hard disk drive to the factory default settings.
• Create rescue media. See “Creating and using a rescue medium” on page 72 for more information about
using a Rescue medium such as a CD or DVD to recover from failures that prevent you from gaining
access to the Windows environment or the Rescue and Recovery workspace on your hard disk drive.

Moving your computer
Take the following precautions before moving your computer.
88

ThinkCentre User Guide

1. Back up all files and data from the hard disk drive. There are a variety of backup programs available
commercially. Your operating system also might have a backup program that you can use. Lenovo

Important WEEE Information

The WEEE marking on Lenovo products applies to countries with WEEE and e-waste regulations (for example,
European Directive 2002/96/EC, India E-Waste Management & Handling Rules, 2011). Appliances are
labeled in accordance with local regulations concerning waste electrical and electronic equipment (WEEE).
These regulations determine the framework for the return and recycling of used appliances as applicable
within each geography. This label is applied to various products to indicate that the product is not to be
thrown away, but rather put in the established collective systems for reclaiming these end of life products.
Users of electrical and electronic equipment (EEE) with the WEEE marking must not dispose of end of
life EEE as unsorted municipal waste, but use the collection framework available to them for the return,
recycle, and recovery of WEEE and to minimize any potential effects of EEE on the environment and
human health due to the presence of hazardous substances. For additional WEEE information go to:

Resources. Computers and monitors are categorized as industrial waste and should be properly disposed
of by an industrial waste disposal contractor certified by a local government. In accordance with the Law
for Promotion of Effective Utilization of Resources, Lenovo Japan provides, through its PC Collecting
and Recycling Services, for the collecting, reuse, and recycling of disused computers and monitors. For
details, visit the Lenovo Web site at http://www.lenovo.com/recycling/japan. Pursuant to the Law for
Promotion of Effective Utilization of Resources, the collecting and recycling of home-used computers
and monitors by the manufacturer was begun on October 1, 2003. This service is provided free of
charge for home-used computers sold after October 1, 2003. For details, visit the Lenovo Web site at
http://www.lenovo.com/recycling/japan.
Disposing of Lenovo computer components
Some Lenovo computer products sold in Japan may have components that contain heavy metals or other
environmental sensitive substances. To properly dispose of disused components, such as a printed circuit
board or drive, use the methods described above for collecting and recycling a disused computer or monitor.
Disposing of disused lithium batteries from Lenovo computers
A button-shaped lithium battery is installed on the system board of your Lenovo computer to provide power
to the computer clock while the computer is off or disconnected from the main power source. If you want to
replace it with a new one, contact your place of purchase or ask for a repair service provided by Lenovo. If
you have replaced it by yourself and want to dispose of the disused lithium battery, insulate it with vinyl tape,
contact your place of purchase, and follow their instructions. If you use a Lenovo computer at home and
need to dispose of a lithium battery, you must comply with local ordinances and regulations.

Battery recycling information for the European Union

Notice: This mark applies only to countries within the European Union (EU).
Batteries or packaging for batteries are labeled in accordance with European Directive 2006/66/EC
concerning batteries and accumulators and waste batteries and accumulators. The Directive determines the
framework for the return and recycling of used batteries and accumulators as applicable throughout the
European Union. This label is applied to various batteries to indicate that the battery is not to be thrown
away, but rather reclaimed upon end of life per this Directive.
In accordance with the European Directive 2006/66/EC, batteries and accumulators are labeled to indicate
that they are to be collected separately and recycled at end of life. The label on the battery may also
include a chemical symbol for the metal concerned in the battery (Pb for lead, Hg for mercury, and Cd for
cadmium). Users of batteries and accumulators must not dispose of batteries and accumulators as unsorted
municipal waste, but use the collection framework available to customers for the return, recycling, and
treatment of batteries and accumulators. Customer participation is important to minimize any potential
effects of batteries and accumulators on the environment and human health due to the potential presence of
hazardous substances. For proper collection and treatment, go to:
