•
  Avoid excessive heat and humidity.
•
  Do not heat, take apart, or throw batteries into fire.
•
  If you will not be using the remote control for a long time, remove the \
batteries.
•
  Ensure that you have the batteries’ polarity (+/–) aligned corre\
ctly.
•
  Do not use new and old batteries together, or use different types of bat\
teries together.
•
  Dispose of used batteries according to your local regulations.
CAUTION
• 
When carrying the projector by the carrying handle, make sure the two screws that attach the carrying handle to 
the projector cabinet are tight. (→ page 5)
 
Insufficient tightening of the two screws could result in the projecto\
r falling and causing injury.
•   Do  not  use  the  tilt-foot  for  purposes  other  than  originally  intended.  Misuses  such  as  using  the  tilt  foot  to  carry 
or hang (from the wall or ceiling) the projector can cause damage to t\
he projector.
•
 
Do not send the projector in a soft case by parcel delivery service or cargo shipment. The projector inside the 
soft case could be damaged.
•

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 sec
u
rity measures are not taken. 
• 
 
Contents of transmissions may be intercepted 
Malicious third parties may purposely intercept the radio waves and steal inform
a
tion contained in the transmis
-
sions,  including  such  personal  information  as  ID  nu
m
bers,  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, intr o duce 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 pro
d
ucts 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 you\
r 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.
