Features of the Projector
Automatic keystone correction function
The vertical angle of the projector is 
detected, so that any vertical keystone 
distortion in the projected images can 
be automatically corrected. (p.34)
Compact and lightweight
The projector has a compact body with a footprint the size of a B5 page 
(19 (D) x 27.6 (W) x 7 (H) cm) and is light in weight (approximately 1.9 kg. (4.2 lbs)), 
making it easy to carry.
Color mode function
The optimum images can be projected simply by selecting the image quality from the 
following six preset settings according to the projection environment being used. 
No other troublesome color adjustments are necessary. (p.41, 49, 50)
  sRGB                   Normal              Meeting
  Presentation         Theatre              Game 
Automatic setup function
When projecting computer images, the signals from the connected computer are 
detected automatically and adjusted so that the optimum images are projected. Even if 
several people are giving presentations using the same projector, the optimum picture 
quality can be obtained simply by disconnecting and reconnecting the computers.
Each individual setting can also be adjusted manually. (p.38)
Brilliant, attractive images
Despite its compact size, the projector can display images at high resolutions with a high 
degree of luminance, providing beautifully clear images even in bright environments.
Easy to Operate
The accessory remote control can be used for operations such as pausing projection 
(see Freeze     on p.45) and zooming in on important areas of an image 
(see E-Zoom on p.47). In addition, the remote control can be used to move the 
pointer around on the computer screen during projection 
(See Wireless Mouse Function on p.21.)
If using the wireless mouse function, you can use the remote control to scroll 
back and forth through pages when projecting a PowerPoint presentation.
