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 en vironments, 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

･Using the end product integrating this module in any other environment where
the risk of interference with other devices or services is perceived or identified as
being harmful.

If uncertain of the policy that applies to the use of wireless devices in a specific
organization or environment (an airplane, for example), ask for authorization to use the
end product integrated into this module before turning it on.
