Body-Worn(Wrist) and Next-to-Mouth Operation
(U.S. and Canada)
This device was tested for typical body-worn (wrist) operations with 0 inches
(0cm) between the user' s body (wrist) and the back of the device.
This device was also tested for typical next-to-mouth (face) operations with 0.39
inches (1cm) between the user' s mouth (face) and the front of the device.
To comply with FCC/ISEDC RF exposure requirements, a minimum separation
distance of 0.39 inches (1cm) must be maintained between the user' s
mouth(face) and the front of the device.
Any accessories containing metallic components may not be used.
Specific Absorption Rate (SAR) values
Your product is a radio transmitter and receiver. It is designed and manufactured
not to exceed the emission limits for exposure to Radio Frequency (RF) energy set
by the Federal Communications Commission (FCC) of the U.S. Government. The
standards include a substantial safety margin designed to assure the safety of all
persons, regardless of age and health.
The exposure standard for wireless products employs a unit of measurement
known as the Specific Absorption Rate, or SAR. In the United States and Canada,
the SAR limit for wrist watch used by the public is 1.6 watts/kg (W/kg) averaged
over one gram of tissue or 4.0 watts/kg (W/kg) averaged over ten gram of tissue.
Tests for SAR are conducted using standard operating positions specified by the
FCC with the product transmitting at its highest certified power level in all tested
frequency bands.
Although SAR is determined at the highest certified power level, the actual SAR
level of the product during operation can be well below the maximum value.
Because the product is designed to operate at multiple power levels and 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.
The highest SAR values for United States are:
* Next-to-Mouth(Face): 0.32 W/kg
* Body-worn(Wrist) : 0.29 W/kg
The highest SAR values for Canada are:
* Next-to-Mouth(Face): 0.27 W/kg
* Body-worn(Wrist) : 0.29 W/kg
