Projector Overview
This section describes the features of the projector, and explains the functions of the projector and 
remote controller keys.
XJ-A141/XJ-A146/XJ-A241/XJ-A246/XJ-A251/XJ-A256
zMercury-free Hybrid Light Source:
A CASIO-original laser and LED hybrid light source delivers high luminance from 2,500 to 
3,000 lumens. This projector does not use a mercury lamp, making it environmentally friendly.
zSlim and compact:
A4 file size and approximately 43 mm slim. Compact enough to install or use just about anywhere.
zHDMI video/audio input:
HDMI (High Definition Multimedia Interface) input support enables direct connectivity with today’s 
HDMI enabled notebook PCs, high-definition video devices (BD, HD DVD, DVD players, etc.), and 
games. The projector supports image projection and audio output from these devices.
zWide projection range:
A wide angle 2X zoom allows projection even when projector-to-screen distance is severely limited. 
When using a projection size of 60 inches, projection can be performed from a distance of 
1.4 meters (XJ-A241/XJ-A246/XJ-A251/XJ-A256) or 1.7 meters (XJ-A141/XJ-A146).
zA wide selection of input sources:
Analog RGB, composite video, component video (Y·Cb·Cr, Y·Pb·Pr), and HDMI input sources are 
supported.
zIntelligent Brightness Control function (Eco Mode):
The projector senses surrounding light levels and adjusts projection brightness automatically as 
required for efficient low-power operation. (Requires “Eco Mode” setting to be set to “On (Auto)”.)
zPointer:
The remote controller can be used to select one of a variety of different pointers for use during 
projection.
zDirect Power On:
The projector can be configured to turn on automatically and start projecting as soon as it is 
plugged into a power outlet.

zWXGA Resolution:
The XJ-A241/XJ-A246/XJ-A251/XJ-A256 models support WXGA (1280 × 800) resolution for optimal 
viewing of content formatted for today’s widescreen displays. This makes it perfect for projecting 
images from widescreen notebook PCs and HD video input sources.
XJ-A146/XJ-A246/XJ-A256
zProjection of Data from USB Memory or a Memory Card without a Computer:
USB memory or a memory card (using a commercially available USB card reader) can be connected 
directly to the projector’s USB port. The projector comes with special software for converting 
PowerPoint presentation data to a format that can be stored to USB memory or a memory card and 
projected without using a computer. Images and movies also can be projected directly from USB 
memory or a memory card.
zMulti Projection Camera (YC-400, YC-430) Connection:
A CASIO Multi Projection Camera can be connected directly to the projector’s USB port for fine 
resolution projection of documents and other images. Document camera capabilities allow 
projection of data without going through a computer.
zGraphic Scientific Function Calculator Connection:
Certain CASIO graphic scientific calculator models can be connected directly to the projector’s 
USB port for projection of the calculator screen contents.
zProjection of Computer Screen Contents via Wireless LAN:
The projector comes with a wireless LAN adapter. After a wireless LAN connection is established, 
the contents of the computer screen can be sent to the projector for projection.
zSupport for Wireless projection from MobiShow:
You can install AWIND’s MobiShow (client software for wireless connection to a projector) on a 
smartphone or mobile terminal, and then use the projector to project photographs and presentation 
files stored in the smartphone or terminal memory.
*Note that the type of terminal and the MobiShow version can limit certain functions or can even 
make projection impossible.

Operations in this manual are presented based on the remote controller that comes with the projector. 
Major operation keys are also provided on the projector unit, so the most of the same procedures can 
also be performed directly on the projector.
Remote Controller Keys
The remote controller does not come with batteries loaded. You need to load the two supplied 
batteries before use.
Important!To avoid running down the batteries, store the remote control unit so its keys are not pressed 
inadvertently.

Locate the projector on a desk, table, or stand that is firm and level. Make sure that you allow 
sufficient space around the sides and back of the projector for proper ventilation. The following 
illustrations show how the projector should be oriented for optimum projection relative to the screen.
zThe projector can be configured for projection from the back of a screen. For details, see 
“Projection Mode” (page 37) under “Screen Settings Main Menu”.
zUse a conveniently located power outlet that you can reach easily when you need to unplug the 
projector.
zDo not allow any objects to be within the area indicated by the dashed line below, which is an area 
within 30cm (11.8 inches) of the projector. Keep all obstacles and other objects at least 30cm away 
from the projector’s vents.
zAirflow from air conditioning equipment can blow the heat being exhausted from the area around 
the projector’s lens in a way that causes heat ripples to appear in the projected image. If this 
happens, adjust the airflow of the air conditioning equipment or move the projector.
Setting Up the Projector
XJ-A141/XJ-A146XJ-A241/XJ-A246/XJ-A251/XJ-A256
Make sure the projector is at a right angle to the screen. Position the projector so the lens side is at the edge of the table, 
etc.
