cables connected to it.
Use a clean, soft, and dry cloth to clean the device shell. Do not use any cleaning
agent or spray to clean the device shell.
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/kilogram (W/kg) averaged over
one gram of tissue. The highest SAR value reported to the FCC and IC for this device type
when tested for use in portable exposure conditions is 1.38 W/kg.
The SAR limit also adopted by Europe is 2.0 W/kg averaged over 10 grams of tissue. The
highest SAR value for this device type when tested in portable exposure conditions is
0.098 W/kg.
