Wireless antennas (select models only)
On select computer models, at least two antennas (1, 2) send and receive signals from one or more
wireless devices. These antennas are not visible from the outside of the computer.
NOTE: For optimal transmission, keep the areas immediately around the antennas free from
obstructions.
To review wireless regulatory notices, see the country-specific section of the Regulatory, Safety and
