Health and Safety Information

Exposure to Radio Frequency (RF) Signals

Certification Information (SAR)

Your wireless phone 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

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 so as to use only the power required 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 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

the ear and worn on the body) as required by the FCC. Body-worn operations are

restricted to Samsung-supplied, approved, or non-Samsung designated accessories

that have no metal and must provide at least 1.5 cm separation between the device,

including its antenna (whether extended or retracted) and the user's body. Non-

compliance with the above restrictions may result in violation of FCC RF exposure

guidelines.

The FCC has granted an Equipment Authorization for this mobile phone with all

reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines.

The maximum SAR values for this model phone as reported to the FCC are:

AMPS mode (Part 22):

Head:

1.36

W/kg; Body-worn:

0.923

W/kg

PCS mode (Part 24):

Head:

0.88

W/kg; Body-worn:

0.667

W/kg
