guaranteed in all conditions. You should not rely solely
on the device for essential communications.
Certification Information (SAR)
THIS DEVICE MEETS THE GOVERNMENT'S
REQUIREMENTS FOR EXPOSURE TO RADIO
FREQUENCY ELECTROMAGNETIC FIELD.
Your device is a low-power radio transmitter and
receiver. When it is turned on, it emits low levels of
radio frequency energy (also known as radio waves or
radio frequency fields).
Governments around the world have adopted
comprehensive international safety guidelines,
developed by scientific organizations, e.g.
International Commission on Non-Ionizing Radiation
Protection (ICNIRP) and Institute of Electrical and
Electronics Engineers Inc. (IEEE), through periodic
and thorough evaluation of scientific studies. These
guidelines establish permitted levels of radio wave
exposure for the general population. The levels
include a safety margin designed to assure the safety
of all persons, regardless of age and health, and to
account for any variations in measurements.
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 while 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.
