Features of the ProjectorThe following six preset colour modes are provided so that you can easily 
obtain the optimum images simply by selecting the image quality.
In addition, if projecting onto blackboards rather than projection screens in 
places such as schools, you can select the Blackboard setting to allow 
images to be projected in their natural tints.
Troublesome colour adjustments can thus be avoided. p.44 , p.52 , p.55
• Dynamic   Presentation  Theatre
 Living Room    sRGB
 Blackboard The brightness of the lamp can be set to one of two settings. If projecting 
images in a dark room or onto a small 
screen and the images are too bright, 
change the setting to Low.
In addition, when the setting is changed to Low, the amount of power 
consumed and noise produced are reduced and the operating life of the lamp 
can be extended.
 Reduction in power consum ption of approximately 20%
 Reduction in operating noi se of approximately 10%
 Approximately 1.5 time s longer lamp life
 p.61
The vertical angle of the projector is de tected, so that any vertical keystone 
distortion in the projected images  can be automatically corrected.    p.38

Features of the ProjectorThe projector has a compact body with a footprint the size of an A4 page (24 
(D)  × 31.5 (W)  × 8.7 (H) cm (9.45 (D)  × 12.4 (W)  × 3.43 (H) in.) and is light 
in weight (approximately 2.9 kg. (6.4 lbs)), making it easy to carry.
Clear and attractive images can be obtained even in bright locations.
The accessory remote control can be used for operations such as pausing 
projection (see Freeze on    p.47) and zooming in on important areas of 
an image (see E-Zoom on    p.49). In addition, the remote control can be 
used to move the pointer around on th e computer screen during projection 
(see Wireless Mouse Function on    p.19). If using the wireless mouse 
function, you can use the remote control to scroll back and forth through 
pages when projecting a PowerPoint presentation. If the password Protect function is em
ployed, a password can be used to 
limit operation of the projector and changing of settings. This means that the 
projector cannot be used if it is taken without authorisation, and thus serves 
as a theft-prevention feature.
