Specific Absorption Rates (SAR) for Wireless Devices
The SAR is a value that corresponds to the relative amount of RF energy absorbed by the user
of a wireless device.
The SAR value of a device is the result of an extensive testing, measuring and calculation
process. It does not represent how much RF the device emits. All devices are tested at their
highest value in strict laboratory settings. But when in operation, the SAR of a device can
be substantially less than the level reported to ISED (Innovation, Science and Economic
Development Canada). This is because of a variety of factors including its proximity to a base
station antenna, design and other factors. What is important to remember is that each device
meets strict federal guidelines. Variations in SAR values do not represent a variation in safety.
All devices must meet the federal standard, which incorporates a substantial margin of safety.
As stated above, variations in SAR values between different model devices do not mean
variations in safety.
SAR values at or below the federal standard limit are considered safe for use by the public. The
federal standard limits are 4.0 W/ kg (10g) of extremity SAR and 1.6W/kg (1g) of Head/Wrist
SAR. The extremity SAR (wrist SAR) has been used for non-speaker modes at a 0 cm device
distance from the body when worn in contact with the wrist. Additionally, for voice activated
transmission, the front of this device has been tested when worn on the wrist and positioned
a minimum of 1.0 cm from the head.
The wireless charger complies with ISED Radiation exposure limits set forth for an
uncontrolled environment. This device and its antenna must not be co-located or operating
in conjunction with any other antenna or transmitter. This equipment should be installed and
operated with a minimum distance of 20 cm between the radiator and your body.
