Exposure to radio waves (SAR)
When your device, the Wi-Fi hotspot functionality or the Bluetooth hands
free functionality is turned on, it emits low levels of radio frequency energy
(radio waves). The radio wave exposure guidelines employ a unit of
measurement known as the Specific Absorption Rate, or SAR. This device
meets the international SAR limit guidelines and your deviceยดs SAR values
are below these limits. The Specific Absorption Rate for your device
is 0.86 W/kg averaged over 10g when worn on your wrist.
SAR data information is provided for residents in countries that have
adopted the SAR limit recommended by the International Commission of
Non-Ionizing Radiation Protection (ICNIRP), which is 2 W/kg averaged over
ten (10) gram of body tissue or recommended by the Institute of Electrical
and Electronics Engineers (IEEE), which is 1.6 W/kg averaged over
one (1) gram of body tissue. Products used on limbs has a international
limit based on ICNIRP recommendations at 4 W/kg averaged over
ten (10) gram of body tissue. These requirements are based on scientific
guidelines that include safety margins designed to assure the safety of all
persons, regardless of age and health.
Tests for SAR are conducted using standardized methods with the
device tra
nsmitting at its highest certified power level in all used frequency
bands, but because the device is designed to use the minimum power
necessary to access the chosen network, the actual SAR level can be well
below this value. While there may be differences between the SAR levels of
various device models, they are all designed to meet the relevant
guidelines for exposure to radio waves.
Your device is used worn on your wrist and has been tested when
positioned at 0 mm from the body without any metal parts in the vicinity of
clock or when properly used with an appropriate accessory and worn on
the wrist.
The WHO (World Health Organization) has stated that current scientific
information does not indicate the need for special precautions for the use
of clocks. For more information about this topic, please refer to the WHO
document (Memo No. 193, Electromagnetic Fields and Public Health,
Mobile phones and their base stations), available at:
