Radio Frequency (RF) Exposure

General Statement on RF Energy

Your phone contains a transmitter and a receiver. When it is
ON, it receives and transmits RF energy. When you
communicate with your phone, the system handling your call
controls the power level at which your phone transmits.

Body Worn Operation

Important safety information regarding radio frequency
radiation (RF) exposure:

45

To ensure compliance with RF exposure guidelines the
phone must be used with a minimum of 15 mm separation
from the body.

Failure to observe these instructions could result in your RF
exposure exceeding the relevant guideline limits.

Limiting Exposure to Radio Frequency (RF)
Fields

For individuals concerned about limiting their exposure to RF
fields, the World Health Organization (WHO) provides the
following advice:

Precautionary measures: Present scientific information does
not indicate the need for any special precautions for the use
of mobile phones. If individuals are concerned, they might
choose to limit their own or their children’s RF exposure by
limiting the length of calls, or using ‘hands-free’ devices to
keep mobile phones away from the head and body.

Further information on this subject can be obtained from the
WHO home page http://www.who.int/peh-emf WHO Fact
sheet 193: June 2000.

devices or magnetic media close to your phone for a long
time.

48

Electrostatic Discharge (ESD)

• Press the buttons lightly.

• Use the special features which are designed to minimize

the times of pressing buttons, such as Message
Templates and Predictive Text.

49

service centre.

Interference

General Statement on Interference

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 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.

51

Hearing Aids

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.

Medical Devices

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

to do so by airport or airline staff.
Consult the airline staff about the use of wireless devices on
