Projector Features
f
Short-distance projection
The shortest recommended projection distance to the screen is a 
remarkably short 54 cm (21 in.)*. You can place the projector close to the 
screen. For example, if you project images onto the screen by a ceiling 
projection, you can stand close to the screen and explain projected images 
without casting your shadow.
Also when you stand with your back to the screen, the light from the 
projector will not come into your sight so you will not be dazzled.
* At this distance, the projected image will measure about 110 
^ 67 cm 
(43 
^ 26 in.).
 
f
WXGA-Compatible projection
The projector can handle the image from a computer with a 16:10 WXGA 
wide LCD display, keeping the aspect ratio as is. This lets you make the 
best use of a wide surface, such as a whiteboard, as a screen.
f
Network-Based control
By connecting the projector to a LAN environment, you can monitor and 
control the projector from a computer.f
Password Protect to restrict and manage users
By setting a password you can restrict who can use the projector. 
s
p.19
f
Operation Lock restricts button operation on the control panel
You can use this to prevent people from changing projector settings 
without permission at events, in schools, and so on. 
s
p.22
f
Equipped with various anti-theft devices
The projector is equipped with the following security devices. 
s
p.23
• Security slot
 Security cable installation point
f
Direct power On/Off
In places where power is managed centrally, such as in a conference 
room, the projector can be set to power on and off automatically when the 
power source to which the projector is connected is switched on or off.
f
No cool down delay
After turning the projectors power off, you can disconnect the projectors 
power cable without having to wait for the projector to cool down first.
