Warning

FCC and FAA regulations may prohibit airborne operation of radio-frequency wireless devices (wireless adapters) because their signals could interfere with critical aircraft instruments. Ask the cabin crew before turning on your device's wireless adapter whilst on board.

The wireless adapter and your health

The wireless adapter, like other radio devices, emits radio frequency electromagnetic energy. The level of energy emitted by the wireless adapter, however, is less than the electromagnetic energy emitted by other wireless devices such as mobile phones. The wireless adapter 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 wireless adapter may be restricted by the proprietor of the building or responsible representatives of the applicable organization. Examples of such situations may include:

• Using the wireless adapter on board airplanes, or
• Using the wireless adapter in any other environment where the risk of interference with other devices or services is perceived or identified as being harmful.

If you are uncertain of the policy that applies to the use of wireless adapters in a specific organization or environment (an airport, for example), you are encouraged to ask for authorization to use the adapter before you turn it on.

USA — FCC and FAA

The FCC, through its action in ET Docket 96-8, has adopted a safety standard for human exposure to radio frequency (RF) electromagnetic energy emitted by FCC-certified equipment. The wireless adapter meets the Human Exposure limits found in OET Bulletin 65, Supplement C, 2001, and ANSI/IEEE C95.1, 1992. Proper operation of this radio according to the instructions in this manual will result in exposure substantially below the FCC's recommended limits.

• The following safety precautions should be observed: Do not touch or move the antenna while the unit is transmitting or receiving.
• Do not hold any component containing the radio such that the antenna is very close to or touching any exposed parts of the body, especially the face or eyes, while transmitting.
• Do not operate the radio or attempt to transmit data unless the antenna is connected; this behavior may cause damage to the radio.
• The use of wireless adapters in hazardous locations is limited by the constraints posed by the safety directors of such environments.
• The use of wireless adapters on airplanes is governed by the Federal Aviation Administration (FAA).

- The use of wireless adapters in hospitals is restricted to the limits set forth by each hospital.
