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.
Specific Absorption Rate (SAR)
Your mobile device is a radio transmitter and receiver. It
is designed not to exceed the limits for exposure to radio
waves recommended by international guidelines. These
guidelines were developed by the independent scientific
organization ICNIRP and include safety margins designed
to assure the protection of all persons, regardless of age
and health.
The guidelines use a unit of measurement known as
Specific Absorption Rate, or SAR. The SAR limit for
mobile devices is 2 W/kg and the highest SAR value for
this device when tested at the head was 0.722 W/kg*,
and when tested at the body was 0.973 W/kg*. As mobile
devices offer a range of functions, they can be used in
other positions, such as on the body as described in this
user guide**.
As SAR is measured utilizing the device's highest
transmitting power, the actual SAR of this device while
operating is typically below that indicated above. This is
due to automatic changes to the power level of the device
to ensure it only uses the minimum power required to
communicate with the network.
* The tests are carried out in accordance with
50360, EN 5066, EN62479, EN 62209-1, EN 62209-2.
** Please see body worn operation.
Body Worn Operation
Important safety information regarding radio frequency
radiation (RF) exposure:
To ensure compliance with RF exposure guidelines the
phone must be used with a minimum of 15 cm separation
from the body.
Only use approved accessories.
Don't rely on your phone as a primary
device for emergency communications.
