Taking care of your device
Your device is a product of superior design and craftsmanship and should be treated with
care. The following suggestions will help you protect your warranty coverage.
Do not use or store the device in dusty, dirty areas. Its moving parts and electronic
•
components can be damaged.
Do not store the device in high or cold temperature. High temperatures can shorten
•
the life of electronic devices, damage batteries, and warp or melt certain plastics.
When the device warms to its normal temperature from a cold temperature,
moisture can form inside the device and damage electronic circuit boards.
Do not attempt to open the device other than as instructed in this guide.
•
Do not drop, knock, or shake the device. Rough handling can break internal circuit
•
boards and fine mechanics.
Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the
•
device. Only use a soft, clean, dry cloth to clean the surface of the device.
Do not paint the device. Paint can clog the moving parts and prevent proper
•
operation.
Use only the supplied or an approved replacement antenna. Unauthorised
•
antennas, modifications, or attachments could damage the device and may violate
regulations governing radio devices.
Use chargers indoors.
•
Backup all data you want to keep, such as contacts and calendar notes.
•
To reset the device from time to time for optimum performance, power off the
•
device and remove the battery.
These suggestions apply equally to your device, battery, charger, or any accessory.
Recycle

dedicated collection points. This way you help prevent uncontrolled waste disposal and
promote the recycling of materials. Check product environmental information and how
to recycle your Nokia products at www.nokia.com/werecycle, or nokia.mobi/werecycle.

Your device and its accessories are not toys. They may contain small parts. Keep them
out of the reach of small children.
Operating environment
This device meets RF exposure guidelines in the normal use position at the ear or at least
2.2 centimetres (7/8 inch) away from the body. Any carry case, belt clip, or holder for
body-worn operation should not contain metal and should position the device the above-
stated distance from your body.
To send data files or messages requires a quality connection to the network. Data files
or messages may be delayed until such a connection is available. Follow the separation
distance instructions until the transmission is completed.
Parts of the device are magnetic. Metallic materials may be attracted to the device. Do
not place credit cards or other magnetic storage media near the device, because
information stored on them may be erased. Your device contains sensors that use
magnets. External magnets may affect the operation of the device.
Medical devices
Operation of radio transmitting equipment, including wireless phones, may interfere
with the function of inadequately protected medical devices. Consult a physician or the
manufacturer of the medical device to determine whether they are adequately shielded
from external RF energy. Switch off your device when regulations posted instruct you to
do so. Hospitals or health care facilities may use equipment sensitive to external RF
energy.
Implanted medical devices
Manufacturers of medical devices recommend a minimum separation of 15.3 centimetres
(6 inches) between a wireless device and an implanted medical device, such as a
pacemaker or implanted cardioverter defibrillator, to avoid potential interference with
the medical device. Persons who have such devices should:
Always keep the wireless device more than 15.3 centimetres (6 inches) from the
•
