Take extra precautions
• Keep the battery or device dry and away from water or any liquid as it may cause
a short circuit.
• Keep metal objects away so they don’t come in contact with the battery or its
connectors as it may lead to short circuit during operation.
• The phone should be only connected to products that bear the USB-IF logo or have
completed the USB-IF compliance program.

Important Customer Information
PREVENTION OF HEARING LOSS
CAUTION: Permanent hearing loss may occur if earphones or headphones
are used at high volume for prolonged periods of time.
SAFETY IN AIRCRAFT
Due to the possible interference caused by this product to an aircraft’s navigation
system and its communications network, using this device’s phone function on board
an airplane is against the law in most countries. If you want to use this device when its
use is restricted on board an aircraft, remember to switch to Airplane Mode which turns
off RF functions that could cause interference.
ENVIRONMENT RESTRICTIONS
Do not use this product in gas stations, fuel depots, chemical plants or where blasting
operations are in progress, or in potentially explosive atmospheres such as fueling
areas, fuel storehouses, below deck on boats, chemical plants, fuel or chemical transfer
or storage facilities, and areas where the air contains chemicals or particles, such as
grain, dust, or metal powders. Please be aware that sparks in such areas could cause
an explosion or fire resulting in bodily injury or even death.
EXPLOSIVE ATMOSPHERES
When in any area with a potentially explosive atmosphere or where flammable
materials exist, the product should be turned off and the user should obey all signs and
instructions. Sparks in such areas could cause an explosion or fire resulting in bodily
injury or even death. Users are advised not to use the equipment at refueling points
such as service or gas stations, and are reminded of the need to observe restrictions on
the use of radio equipment in fuel depots, chemical plants, or where blasting operations
are in progress. Areas with a potentially explosive atmosphere are often, but not always,
clearly marked. These include fueling areas, below deck on boats, fuel or chemical
transfer or storage facilities, and areas where the air contains chemicals or particles,

6Important Customer Information
such as grain, dust, or metal powders.
ROAD SAFETY
Vehicle drivers in motion are not permitted to use communication services with
handheld devices, except in the case of emergency. In some countries, using hands-
free devices as an alternative is allowed.
SAFETY PRECAUTIONS FOR RF EXPOSURE
• Avoid using your phone near metal structures (for example, the steel frame of a
building).
• Avoid using your phone near strong electromagnetic sources, such as microwave
ovens, sound speakers, TV and radio.
• Use only original manufacturer-approved accessories, or accessories that do not
contain any metal.
• Use of non-original manufacturer-approved accessories may violate your local RF
exposure guidelines and should be avoided.
INTERFERENCE WITH MEDICAL EQUIPMENT FUNCTIONS
This product may cause medical equipment to malfunction. The use of this device is
prohibited in most hospitals and medical clinics.
If you use any personal medical device(s), consult the manufacturer of your device(s)
to determine if the device(s) are adequately shielded from external RF energy. Your
physician may be able to assist you in obtaining this information. Turn your phone OFF
in health care facilities when any regulations posted in these areas instruct you to do
so. Hospitals or health care facilities may be using equipment that could be sensitive to
external RF energy.
HEARING AIDS
Some digital wireless phones may interfere with some hearing aids. In the event of such
interference, you may want to consult your service provider, or call the customer service
line to discuss alternatives.

Important Customer Information
NON-IONIZING RADIATION
Your device has an internal antenna. This product should be operated in its normal-use
position to ensure the radiative performance and safety from interference. As with other
mobile radio transmitting equipment, users are advised that for satisfactory operation
of the equipment and for personal safety, it is recommended that no part of the human
body be allowed to come too close to the antenna during operation of the equipment.
Use only the supplied integral antenna. Use of unauthorized or modified antennas may
impair call quality and damage the phone, causing loss of performance and SAR levels
exceeding the recommended limits as well as result in non-compliance with local
regulatory requirements in your country. To assure optimal phone performance and
ensure human exposure to RF energy is within the guidelines set forth in the relevant
standards, always use your device only in its normal-use position. Contact with the
antenna area may impair call quality and cause your device to operate at a higher
power level than needed. Avoiding contact with the antenna area when the phone is IN
USE optimizes the antenna performance and the battery life.
