* In the United States and Canada, the SAR limit for mobile
USB devices used by the public is 1.6 watts/kg (W/kg)
averaged over one gram of tissue. The standard incorporates
a substantial margin of safety to give additional protection
for the public and to account for any variations in
measurements.
TIA Safety Information
The following is the complete TIA Safety Information for
wireless handheld USB devices.
Exposure to Radio Frequency Signal
Your wireless handheld portable USB device is a low power
radio transmitter and receiver. When ON, it receives and sends
out Radio Frequency (RF) signals.
In August, 1996, the Federal Communications Commissions
(FCC) adopted RF exposure guidelines with safety levels for
handheld USB Devices. Those guidelines are consistent with
the safety standards previously set by both U.S. and
international standards bodies:
ANSI C95.1 (1992) *
NCRP Report 86 (1986)
ICNIRP (1996)
* American National Standards Institute; National Council on
Radiation Protection and Measurements; International
Commission on Non-Ionizing Radiation Protection
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).
The design of your USB device complies with the FCC
guidelines (and those standards).
Antenna Care
Use only the supplied or an approved replacement antenna.
Unauthorized antennas, modifications, or attachments could
damage the USB Device and may violate FCC regulations.
Tips on Efficient Operation
For your USB device to operate most efficiently:
Don't touch the antenna unnecessarily when the USB Device
is in use. Contact with the antenna affects call quality and
may cause the USB Device to operate at a higher power level
than otherwise needed.
