FCCRadioFrequencyExposurestatement

This radiodevice has been evaluated under FCC Bulletin OET65 Cand found compliant with the requirements asset forth in CFR47 Sections 2.1091, 2.1093, and 15.247(b)(4) addressing RF Exposure from radio frequency devices. The radiated output power of this radio device is far below the FCC radio frequency exposure limits. Nevertheless, this device shall be used in such a manner that the potential for human contact during normal operation is minimized. When using this device, a certain separation distance between antenna and nearby persons must be maintained to ensure RF exposure compliance. In order to comply with RF exposure limits established in the ANSI C95.1 standards, the distance between the antennas and the users should not be less than 20 cm (8 inches).

RegulatoryNotesandStatements

Radiodevice, Health and Authorization for use

Radio frequency electromagnetic energy is emitted from the radio devices. The energy levels of theseemissions, however, are far much less than the electromagnetic energy emissions from wireless devices such as mobile phones. Radiodevices are safe for use by consumers because they operate within the guidelines found in radio frequency safety standards and recommendations.

The use of the radiodevices may be restricted in some situations or environments, such as:

• onboardanairplane,or
  •inanexplosiveenvironment,or
• in situations where the interference risk to other devices or services is perceivedoridentifiedasharmful.
