Interference
GeneralStatementonInterface
Care must be taken when using the phone in close proximity to
personal medical devices, such as pacemakers and hearing aids.
Pacemakers
Pacemaker manufacturers recommend that a minimum separation of
15 cm be maintained between a mobile phone and a pacemaker to avoid
27
potential interference with the pacemaker. To achieve this, use the phone
on the opposite ear to your pacemaker and do not carry it in a breast
pocket.
HearingAids
People with hearing aids or other cochlear implants may experience
interfering noises when using wireless devices or when one is nearby.
The level of interference will depend on the type of hearing device and
the distance from the interference source, increasing the separation
between them may reduce the interference. You may also consult your
hearing aid manufacturer to discuss alternatives.
MedicalDevices
Please consult your doctor and the device manufacturer to determine if
operation of your phone may interfere with the operation of your medical
device.
Hospitals
Switch off your wireless device when requested to do so in hospitals,
clinics or health care facilities. These requests are designed to prevent
possible interference with sensitive medical equipment.
Aircraft
Switch off your wireless device whenever you are instructed to do so
by airport or airline staff.
Consult the airline staff about the use of wireless devices on board the
aircraft. If your device offers a ‘flight mode’, this must be enabled prior to
boarding an aircraft.
28

Note: This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that

Healthandsafetyinformation
RadioFrequ+ency(RF)Energy
This model phone meets the government’s requirements for exposure
to radio waves.
This phone is designed and manufactured not to exceed the emission
limits for exposure to radio frequency (RF) energy set by the Federal
Communications Commission of the U.S. Government:
as described in this user guide, is 0.699 W/kg (Body-worn measurements
30
The exposure standard for wireless mobile phones employs a unit of
measurement known as the Specific Absorption Rate, or SAR. The SAR
limit set by the FCC is 1.6W/kg. Tests for SAR are conducted using
standard operating positions accepted by the FCC with the phone
transmitting at its highest certified power level in all tested frequency bands.
Although the SAR is determined at the highest certified power level, the
actual SAR level of the phone while operating can be well below the
maximum value. This is because the phone is designed to operate at
multiple power levels so as to use only the poser required to reach the
network. In general, the closer you are to a wireless base station antenna,
the lower the power output.
The highest SAR value for the model phone as reported to the FCC
when tested for use at the ear is 0.250 W/kg and when worn on the body,
differ among phone models, depending upon available enhancements and
FCC requirements).
While there may be differences between the SAR levels of various
phones and at various positions, they all meet the government requirement.
The FCC has granted an Equipment Authorization for this model
phone with all reported SAR levels evaluated as in compliance with the
FCC RF exposure guidelines. SAR information on this model phone is on
file with the FCC and can be found under the Display Grant section of
http://www.fcc.gov/oet/fccid after searching on
FCC ID: 2AGAQDRAGON
For body worn operation, this phone has been tested and meets the
FCC RF exposure guidelines for use with an accessory that contains no
metal and the positions
