Health And Safety Information
Exposure To Radio Frequency (RF) Signals
Certification Information (SAR)
Your Jitterbug is a radio transmitter and receiver. It is designed and manufactured
not to exceed the exposure limits for radio frequency (RF) energy set by the Federal
Communications Commission (FCC) of the U.S. government.
These FCC exposure limits are derived from the recommendations of two expert
organizations, the National Counsel on Radiation Protection and Measurement (NCRP)
and the Institute of Electrical and Electronics Engineers (IEEE).
In both cases, the recommendations were developed by scientific and engineering
experts drawn from industry, government and academia after extensive reviews of the
scientific literature related to the biological effects of RF energy.
The exposure limit set by the FCC for wireless mobile phones employs a unit of
128 Health and Safety Information
measurement known as the Specific Absorption Rate (SAR). The SAR is a measure of
the rate of absorption of RF energy by the human body expressed in units of watts per
kilogram (W/kg). The FCC requires wireless phones to comply with a safety limit of 1.6
watts per kilogram (1.6 W/kg).
The FCC exposure limit incorporates a substantial margin of safety to give additional
protection to the public and to account for any variations in measurements.
SAR tests are conducted using standard operating positions accepted by the FCC with
the phone transmitting at its highest certified power level in all tested frequency bands.
Although the SAR is determined at the highest certified power level, the actual SAR level
of the phone while operating can be well below the maximum value. This is because the
phone is designed to operate at multiple power levels to use as little power as possible
to reach the network. In general, the closer you are to a wireless base station antenna,
the lower the power output.
Before a new model phone is available for sale to the public, it must be tested and
certified to the FCC to ensure that it does not exceed the exposure limit established by
the FCC. Tests for each model phone are performed in positions and locations (e.g. at
