Health And Safety Information

Exposure To Radio Frequency (RF) Signals

Certication 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scienticandengineering

experts drawn from industry, government and academia after extensive reviews of the

scienticliteraturerelatedtothebiologicaleffectsofRFenergy.

The exposure limit set by the FCC for wireless mobile phones employs a unit of

measurementknownastheSpecic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certiedpowerlevelinalltestedfrequencybands.

AlthoughtheSARisdeterminedatthehighestcertied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

certied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
