FCC RF Exposure Information
WARNING! Read this information before operating the phone.
In August 1996, the Federal Communications Commission (FCC) of the
United States, with its action in Report and Order FCC 96-326, adopted
an updated safety standard for human exposure to Radio Frequency (RF)
electromagnetic energy emitted by FCC regulated transmitters. Those
guidelines are consistent with the safety standard previously set by both U.S.
and international standards bodies. The design of this phone complies with
the FCC guidelines and those international standards.
Bodily Contact During Operation
This device was tested for typical use with the back of the phone kept
0.39 inches (1.0 cm) from the body. To comply with FCC RF exposure
requirements, a minimum separation distance of 0.39 inches (1.0 cm)
must be maintained between the user's body and the back of the
phone, including the antenna. Third-party belt-clips, holsters, and similar
accessories containing metallic components should not be used. Avoid
the use of accessories that cannot maintain 0.39 inches (1.0 cm) distance
between the user's body and the back of the phone and have not been
tested for compliance with FCC RF exposure limits.
Vehicle-Mounted External Antenna
(Optional, if available.)
To satisfy FCC RF exposure requirements, keep 8 inches (20 cm) between
the user / bystander and vehicle-mounted external antenna. For more
information about RF exposure, visit the FCC website at www.fcc.gov.
