Cautions on security when using wireless LAN products 
With  a  wireless  LAN,  radio  waves  are  used  instead  of  LAN  cables  for  the  exchange  of  data  between  the  wireless 
access  points  (computers,  etc.),  offering  the  advantage  that  LAN  connections  can  be  made  freely  within  the  range 
of the radio waves.
On the other hand, the radio waves reach all points within this range, regardless of walls or other obstacles, possi-
bly resulting in the problems described below if the proper security measures are not taken. 
•  Contents of transmissions may be intercepted 
Malicious third parties may purposely intercept the radio waves and steal information contained in the transmis-
sions,  including  such  personal  information  as  ID  numbers,  passwords,  credit  card  numbers,  e-mail  messages, 
etc. 
• Improper intrusions 
Malicious  third  parties  may  without  permission  access  the  personal  or  company  network  and  steal  personal  or 
confidential information, pretend to be someone else and leak incorrect information, rewrite information that has 
been intercepted, introduce computer viruses or otherwise damage data or the system, etc. 
Wireless  LAN  cards  and  wireless  access  points  generally  include  security  measures  for  dealing  with  these  prob-
lems. Making the proper security settings before using the products can reduce the risk of such problems arising. 
We recommend that you fully understand the problems that can arise when using the products without making the 
security settings, then that you make the security settings based on your own decision and at your own discretion. 
Operation  of  the  USB Wireless  LAN  Unit  is  subjected  to  the  regulations  of  the  countries  listed  below,  and  may  be 
prohibited  to  use  outside  the  country  where  you  purchased.  If  you  need  to  use  the  projector  outside  the  country 
where you purchased, you must remove the USB Wireless LAN Unit from the projector before exporting.
