Using electrical power
• This product should be operated from the type of power indicated on
the marking label. If you are not sure of the type of power available,
consult your dealer or local power company.
• Do not allow anything to rest on the power cord. Do not locate this
product where people will walk on the cord.
• If an extension cord is used with this product, make sure that the total
ampere rating of the equipment plugged into the extension cord does
not exceed the extension cord ampere rating. Also, make sure that the
total rating of all products plugged into the wall outlet does not exceed
the fuse rating.
• Do not overload a power outlet, strip or receptacle by plugging in too
many devices. The overall system load must not exceed 80% of the
branch circuit rating. If power strips are used, the load should not
exceed 80% of the power strip's input rating.
• This product's AC adapter is equipped with a three-wire grounded
plug. The plug only fits in a grounded power outlet. Make sure the
power outlet is properly grounded before inserting the AC adapter plug.
Do not insert the plug into a non-grounded power outlet. Contact your
electrician for details.

Information for your safety and comfort - 5
Warning! The grounding pin is a safety feature. Using a power
outlet that is not properly grounded may result in electric shock
and/or injury.
Note: The grounding pin also provides good protection from
unexpected noise produced by other nearby electrical devices that
may interfere with the performance of this product.
• The system can be powered using a wide range of voltages; 100 to 120
or 220 to 240 V AC. The power cord included with the system meets
the requirements for use in the country/region where the system was
purchased. Power cords for use in other countries/regions must meet
the requirements for that country/region. For more information on
power cord requirements, contact an authorized reseller or service
provider.
Protecting your hearing
Warning: Permanent hearing loss may occur if earphones
or headphones are used at high volume for prolonged
periods of time.
To protect your hearing, follow these instructions.
• Increase the volume gradually until you can hear clearly and
comfortably.
• Do not increase the volume level after your ears have adjusted.
• Do not listen to music at high volumes for extended periods.

may get hot. To avoid injury, ensure they do not come in contact with
your skin or body.
• Your device and its enhancements may contain small parts. Keep them
out of the reach of small children.

Guidelines for safe battery usage
This notebook uses a Lithium-ion battery. Do not use it in a humid, wet or
corrosive environment. Do not put, store or leave your product in or near
a heat source, in a high temperature location, in strong direct sunlight, in
a microwave oven or in a pressurized container, and do not expose it to
temperatures over 60° C (140° F). Failure to follow these guidelines may
cause the battery to leak acid, become hot, explode or ignite and cause
injury and/or damage. Do not pierce, open or disassemble the battery. If
the battery leaks and you come into contact with the leaked fluids, rinse
thoroughly with water and seek medical attention immediately. For safety
reasons, and to prolong the lifetime of the battery, charging will not occur
at temperatures below 0° C (32° F) or above 40° C (104° F).
The full performance of a new battery is achieved only after two or three
complete charge and discharge cycles. The battery can be charged and
discharged hundreds of times, but it will eventually wear out. When the
operation time becomes noticeably shorter than normal, buy a new
battery. Use only the approved batteries, and recharge your battery only
with the approved chargers designated for this device.

Information for your safety and comfort - 9
Use the battery only for its intended purpose. Never use any charger or
battery that is damaged. Do not short-circuit the battery. Accidental
short-circuiting can occur when a metallic object such as a coin, clip or
pen causes direct connection of the positive (+) and negative (-) terminals
of the battery. (These look like metal strips on the battery.) This might
happen, for example, when you carry a spare battery in your pocket or
purse. Short-circuiting the terminals may damage the battery or the
connecting object.
The capacity and lifetime of the battery will be reduced if the battery is left
in hot or cold places, such as in a closed car in summer or winter. Always
try to keep the battery between 15°C and 25°C (59°F and 77°F). A device
with a hot or cold battery may not work temporarily, even when the
battery is fully charged. Battery performance is especially limited in
temperatures well below freezing.
Do not dispose of batteries in a fire as they may explode. Batteries may
also explode if damaged. Dispose of batteries according to local
regulations. Please recycle when possible. Do not dispose as household
waste.
Wireless devices may be susceptible to interference from the battery,
which could affect performance.
Note: Please refer to www.acer.com for battery shipping
documents.

Replacing the battery pack
The notebook uses lithium batteries. Replace the battery with the same
type as that which came bundled with your product. Use of another
battery may present a risk of fire or explosion.
Warning! Batteries may explode if not handled properly. Do not
disassemble or dispose of them in fire. Keep them away from
children. Follow local regulations when disposing of used
batteries.
