FCC RF EXPOSURE INFORMATION
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
device 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.
All persons must be at least 20 cm from the antenna when the transmitter is operating
to comply with FCC RF exposure requirements.
