aff ected by radio interference from the product, as can air-
craft navigational equipment.  Users with implantable cardiac 
pacemakers should remain at least 30 cm from the product. 
Turn the product off  in trains and other crowded places, and 
either turn the product off  or disable all wireless transmis-
sions in the vicinity of medical devices, when in medical insti-
tutions and other locations in which wireless devices are pro-
hibited, or when so instructed by airline personnel.  Contact 
the airline for more information on using wireless devices on 
aircraft.  If use of the wireless features of this product causes 
radio interference, disable the wireless features or turn the

accidents or product malfunction.

Security
Although one of the benefi ts of this product is that it allows 
others to freely connect for the wireless exchange of data 
anywhere within its range, the following may occur if secu-

transmissions to steal user IDs, passwords, and other per-
sonal information.

• Unauthorized access: Unauthorized users may gain access to the 

network and alter data or perform other malicious actions.

Note that due the design of wireless networks, specialized 
attacks may allow unauthorized access even when security 
is enabled.
