Safety

The end product integrating this module, like other radio devices, emits radio
frequency electromagnetic energy. The level of energy emitted by this device,
however, is less than the electromagnetic energy emitted by other wireless devices
such as mobile phones. The end product integrating this module operates within
the guidelines found in radio frequency safety standards and recommendations.
These standards and recommendations reflect the consensus of the scientific
community and result from deliberations of panels and committees of scientists
who continually review and interpret the extensive research literature. In some
situations or environments, the use of the end product integrating this module may
be restricted by the proprietor of the building or responsible representatives of the
applicable organization. Examples of such situations include the following:

･Using the end product integrating this module onboard airplanes, or
