FCC RF EXPOSURE INFORMATION:
WARNING!! Read this information before using your phone
In August 1986 the Federal Communications Commission (FCC) of the United States with its
action in Report and Outer 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 these
international standards. Use only the supplied or an approved antenna. Unauthorized antennas
modifications, or attachments could impair call quality, damage the phone, or result in violation
of FCC regulations. Do not use the phone with a damaged antenna. If a damaged antenna comes
into contact with the skin, a minor burn may result. Please contact your local dealer for
replacement antenna.
BODY-WORN OPERATION:
This device was tested for typical body-worn operations with the back of the phone kept 10mm
from the body. To comply with FCC RF exposure requirements, a minimum separation distance
of 10mm 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
shall not be used. Body-worn accessories that cannot maintain 10mm separation distance between
the user’s body and the back of the phone, and have not been tested for typical body-worn
operations may not comply with FCC RF exposure limits and should be avoided.
For more information about RF exposure, please visit the FCC website at www.fcc.gov
Your wireless handheld portable telephone is a low power radio transmitter and receiver. When
it is ON, it receives and also sends out radio frequency (RF) signals. In August, 1996, the Federal
Communications Commissions (FCC) adopted RF exposure guidelines with safety levels for
hand-held wireless phones. Those guidelines are consistent with the safety standards previously
set by both U.S. and international standards bodies:
 (1992) /  (1986) /  (1996)
Those standards were based on comprehensive and periodic evaluations of the relevant
scientific literature. For example, over 120 scientists, engineers, and physicians from universities,
government health agencies, and industry reviewed the available body of research to develop
the ANSI Standard (C95.1). Nevertheless, we recommend that you use a hands-free kit with
your phone (such as an earpiece or headset) to avoid potential exposure to RF energy. The
design of your phone complies with the FCC guidelines (and those standards).
Use only the supplied or an approved replacement antenna. Unauthorized antennas,
modifications, or attachments could damage the phone and may violate FCC regulations.
NORMAL POSITION:
Hold the phone as you would any other telephone with the antenna pointed up and over your
shoulder.

conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may

unauthorized modifications to this equipment. Such modifications could void the user’s
authority to operate the equipment.
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
