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. 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 SARs 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 of 1.6 W/kg are
considered safe for use by the public.
SAR values are measured in positions that simulate uses against the head and held to
the ear. SAR values for body-worn operations refer to accessories (i.e., device case and
device holster) that contains no metal at a minimum distance of 1.5 cm from the body.
If your device supports the wireless power sharing function, this equipment should be
operated with a minimum distance of 10cm between the device and your body.
If Wireless charger is supported, 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 10 cm between the radiator and your body.
