12.4 Specific Absorption Rate Information
12.4.1 United States Radiation Exposure Statement
This device meets the government’s requirements for exposure to radio waves. This device is
designed and manufactured not to exceed the emission limits for exposure to Radio Frequency
(RF) energy set by the Federal Communications Commission of the U.S. Government. The
exposure standard for wireless devices employs a unit of measurement known as the Specific
Absorption Rate (SAR). The SAR limit set by the FCC is 1.6 W/2.2 lbs. (1.6 W/kg). Tests for
SAR are conducted using standard operating positions accepted by the FCC with the device
transmitting at its highest certified power level in all tested frequency bands. No minimum
separation distance needs to be maintained between the user’s body and the device, including
the antenna, during body-worn operation to comply with the RF exposure requirements in the
United States and Canada. The limit recommended by FCC and IC is 1.6 W/2.2 lbs. (1.6 W/kg)
averaged over 0.04 oz. (1 g) of tissue.
The highest SAR value of the RealWear Navigator for use by ear is 0.95 W/2.2 lbs. (0.95 W/kg)
averaged over 0.04 oz. (1 g) of tissue.
12.4.2 Europe Radiation Exposure Statement
No minimum separation distance needs to be maintained between the user's body and the
device, including the antenna during body-worn operation to comply with the RF Exposure
requirements in Europe. The limit recommended by RED is 2 W/kg (2 W/2.2 lbs.) average over
10 g (0.4 oz.) of tissue.
The highest SAR value of the RealWear Navigator for use by the ear is 0.267 W/kg (0.267
W/2.2 lbs. average over 10 g (4 oz.) of tissue.
12.4.3 Canada Radiation Exposure Statement
The product complies with the Canada portable RF exposure limit set forth for an uncontrolled
environment and is safe for intended operation as described in this manual. The further RF
exposure reduction can be achieved if the product can be kept as far as possible from the user
body or set the device to lower output power if such function is available.
