Your phone is designed and manufactured notto exceed the emission limits for exposure to radiofrequency (RF) energy set by the FederalCommunications Commission of the U.S. Government.These limits are part of comprehensive guidelines andestablish permitted levels of RF energy for the generalpopulation. The guidelines are based on standards thatwere developed by independent scientific organizationsthrough periodic and thorough evaluation of scientificstudies.The exposure standard for wireless mobile phonesemploys a unit of measurement known as the SpecificAbsorption Rate (SAR).The SAR limit set by the FCC is 1.6 W/kg.*Tests for SAR are conducted using standard operatingpositions accepted by the FCC with the phonetransmitting at its highest certified power level in alltested frequency bands. Although the SAR is determinedat the highest certified power level, the actual SAR levelof the phone while operating can be well below themaximum value. This is because the phone is designedto operate at multiple power levels so as to use only thepower required to reach the network. In general, thecloser you are to a wireless base station antenna, thelower the output. Before a phone model is available forsale to the public, it must be tested and certified to theFCC that it does not exceed the limit established by theU.S. government-adopted requirement for safe exposure.The tests are performed on position and locations (forexample, at the ear and worn on the body) as required byFCC for each model. The highest SAR value for thismodel phone as reported to the FCC when tested for useat the ear is 1.14 W/kg, and when worn on the body, is1.21 W/kg. (Body-worn measurements differ amongphone models, depending upon available accessoriesand FCC requirements). While there may be differencesbetween the SAR levels of various phones and at variouspositions, they all meet the U.S. governmentrequirement.The FCC has granted an Equipment Authorization forthis model phone with all reported SAR levels evaluatedas in compliance with the FCC RF exposure guidelines.SAR information on this phone is on file with the FCCProduct name Battery pack N1101WBBattery type Lithium ion batteryNominal voltage 3.7 V DCNominal capacity 1230 mAh
