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.

Body-worn Operation
This device was tested for typical body-worn operations. To comply With RF exposure
requirements, a minimum separation distance of 1.0cm must be maintained between the
user’s body and the handset, including the antenna.
Third-party belt-clips, holsters, and similar including the antenna. Third-party belt-clips,
holsters, and similar accessories used by this device should not contain any metallic
components. Body-worn accessories that do not meet these requirements may not
comply with RF exposure requirements and should be
avoided.
Specific Absorption Rate (SAR) information:
This wireless phone meets the government's requirements for exposure to radio waves.
The guidelines 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 or health.
FCC RF Exposure Information and Statement. The SAR limit of USA (FCC) is 1.6W/kg
averaged over one gram of tissue.
Device types: T5921 has also been tested against this SAR limit. The highest SAR value
reported under this standard during product certification when properly worn on the
body is 1.218W/kg (1gSAR, test distance:5mm, limit 1.6W/kg), 1.529W/kg(10gSAR,
test distance:0mm, limit 4W/kg) and 1.359W/kg(1gSAR, test distance:19mm(power
sensor), limit 1.6W/kg). This device was tested for body-worn operations with the back
of the handset kept 10mm and 5mm from the body. To maintain compliance with FCC
RF exposure requirements, use accessories that maintain a 10mm and 5mm separation
distance between the user's body and the back of the handset. The use of belt clips,
holsters and similar accessories should not contain metallic components in its assembly.
The use of accessories that do not satisfy these requirements may not comply with FCC
RF exposure requirements, and should be avoided.
