Wireless Antennae (Select Models Only)

Component Description

Antennae (2)* Send and receive wireless device signals.

ÅExposure to Radio Frequency Radiation.

The radiated output power of this device is below the FCC radio frequency exposure limits. Nevertheless, the device should be used in such a manner that the potential for human contact during normal operation is minimized. To avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antennae should be not less than 20 cm

(8 inches) during normal operation, including when the notebook display is closed.

To establish a wireless connection, a wireless network must already be set up. For more information, refer to Chapter 11, “Wireless (Select Models Only).”

*The antennae are not visible from the outside of the notebook. For optimal transmission, keep the areas immediately around the antennae free from obstructions
