Certification Information (SAR)
This device meets guidelines for exposure to radio waves.
Your device is a low-power radio transmitter and receiver. As
recommended by international guidelines, the device is
designed not to exceed the limits for exposure to radio waves.
These guidelines were developed by the independent scientific
organization International Commission on Non-Ionizing
Radiation Protection (ICNIRP) and include safety measures
designed to ensure safety for all users, regardless of age and
health.
The Specific Absorption Rate (SAR) is the unit of measurement
for the amount of radio frequency energy absorbed by the body
when using a device. The SAR value is determined at the
highest certified power level in laboratory conditions, but the
actual SAR level of the device when being operated can be well
below the value. This is because the device is designed to use
the minimum power required to reach the network.
The SAR limit adopted by USA and Canada is 1.6 watts/
