SAR Data
This model wireless phone meets the government’s 
requirements for exposure to radio waves.
Your wireless phone is a radio transmitter and receiver. It is designed and 
manufactured not to exceed limits for exposure to radio frequency (RF) 
energy set by the Federal Communications Commission (FCC) of the U.S. 
Government and by the Canadian regulatory authorities. These limits are 
part of comprehensive guidelines and establish permitted levels of RF 
energy for the general population. The guidelines are based on standards 
that were developed by independent scientific organizations through 
periodic and thorough evaluation of scientific studies. The standards 
include a substantial safety margin designed to assure the safety of all 
persons, regardless of age or health.
The exposure standard for wireless mobile phones employs a unit of 
measurement known as the Specific Absorption Rate, or SAR. The SAR 
limit set by the FCC and by the Canadian regulatory authorities is 
1.6 W/kg.

 Tests for SAR are conducted using standard operating positions 
accepted by the FCC and by Industry Canada 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, the lower the power output.
Before a phone model is available for sale to the public in the U.S. and 
Canada, it must be tested and certified to the FCC and Industry Canada 
that it does not exceed the limit established by each government for safe 
exposure. The tests are performed in positions and locations (e.g., at the 
ear and worn on the body) reported to the FCC and available for review by 
Industry Canada. The highest SAR value for this model phone when tested 
for use at the ear is 1.13 W/kg, and when worn on the body, as described 
in this user guide, is 0.86 W/kg. The SAR value for this product in its data 
transmission mode (body-worn use) is 0.81 W/kg. (Body-worn 
measurements differ among phone models, depending upon available 
accessories and regulatory requirements).

While there may be differences between the SAR levels of various phones 
and at various positions, they all meet the governmental requirements for 
safe exposure. Please note that improvements to this product model could 
cause differences in the SAR value for later products; in all cases, products 
are designed to be within the guidelines.

1. In the United States and Canada, the SAR limit for mobile phones 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.
2. The SAR information includes the Motorola testing protocol, assessment 
procedure, and measurement uncertainty range for this product.
