FCC RF Exposure Information
The guidelines established by the FCC are based on standards that were
developed by independent scientific organizations through periodic and
thorough evaluation of scientific studies. The standards include a substantial
safety margin designed to assure the safety of all persons, regardless of age
and health.
The exposure standard for wireless handsets employs a unit of measurement
known as the Specific Absorption Rate (SAR). The SAR limit set by the FCC is
1.6 W/kg.
The tests are performed according to FCC standards for each model and the
maximum SAR value for this model handset, when tested next to the body as
described in this user guide, is 0.856 W/kg.
Placement on the body: Measurements for the 921T were taken with the
normal position as the rear of the phone facing the body at a distance of
1.5 cm. In order to maintain compliance with FCC RF exposure requirements,
use accessories that maintain a 1.5 cm separation distance between the body
and the back of the handset. Choose accessories, such as belt clips and
holsters, that do not contain metallic components.
The use of accessories that do not satisfy these requirements may not comply
with FCC RF exposure requirements, and should be avoided. Additional
information on Specific Absorption Rates (SAR) can be found on the
homepage listed below:

European RF Exposure Information
Your mobile device is a radio transmitter and receiver. It is designed not to
exceed limits recommended by international guidelines for exposure to radio
waves. These guidelines were developed by the independent scientific
organization International Commission on Non-Ionizing Radiation Protection
(ICNIRP) and include safety margins designed to assure the protection of all
persons, regardless of age and health.
The exposure standard for wireless handsets employs a unit of measurement
known as the Specific Absorption Rate (SAR). The SAR limit for mobile devices
is 2 W/kg and the highest SAR value for this device when positioned near the
body is 0.531 W/kg*.
As SAR is measured utilizing the device's highest transmitting power the
actual SAR of this device during operation is typically below that indicated
above. This is because the handset was designed to use the minimum level of
transmission power necessary to communicate with the mobile network. The
World Health Organization (WHO) has stated that present scientific
information does not indicate the need for any special precautions for the use
of mobile devices. They note that if you want to reduce your exposure then
you can do so by limiting the length of calls or using a "hands-free" device to
keep the mobile phone away from the head and body. Additional information
about SAR can be found at the WHO homepage listed below.

* These tests for wearing the mobile device on the body are carried out in
accordance with FCC standards and the values are based on European
requirements.
