a self-check may cause the projector to restart automatically. This normally does not 
indicate malfunction, so you can continue using the projector.
However, malfunction may be indicated if successive restarts keep occurring. If this 
happens contact your original dealer or authorized CASIO service center.

This section explains how to establish a component video connection between the projector and a 
video device.
zComponent video output terminals come in 3-terminal sets: Y·Cb·Cr or Y·Pb·Pr. Be sure to match 
the colors of the plugs on a component video cable with the colors of the terminals (Green: Y; 
Blue: Cb/Pb; Red: Cr/Pr).
zNote that connection only to an analog component video output terminal is supported.
Connection to a digital output terminal is not supported.

The projector’s firmware (software in the projector flash ROM) can be updated and user logo images 
can be transferred to the projector from a computer connected to the projector’s LOGO port (USB 
port for ROM updating) with a USB cable.
To connect the projector’s LOGO port with a computer’s USB 
port
Use a commercially available USB cable to connect the projector’s LOGO port to the computer’s USB 
port.
Use a USB cable with a micro USB plug on one end for connection to the projector’s LOGO port, and 
a plug on the other end with a shape that is compatible with the computer USB port.
NotezFor details about how to update the firmware and how to transfer a user logo to the projector, 
see the “User Logo Transfer Guide” and the “Projector Firmware Update Guide”, which are 
available at the CASIO website.

The projector can be hung from a ceiling. When doing so, the projector should be turned upside down, 
and secured to the ceiling.
For full details, contact the retailer where you purchased the projector.
Important!zWhen hanging the projector from a ceiling, make sure that it is at least one meter away from 
fire detectors, fire alarms, and other fire protection devices. Locating the projector too close to 
a fire protection device creates the risk of mis-operation of the device due to warm air 
exhausted from the projector. Also, avoid locating the projector close to fluorescent lights or 
other strong light sources. Bright light can shorten the operating range of the remote controller 
or even make remote control impossible. When selecting a location for the projector, be sure 
to test for proper operation of the remote controller.
zThe vertical and horizontal orientation of the projected image is reversed from the normal 
configuration when projecting from a projector hung from the ceiling. You need to change the 
setup of the projector in order to correct for this. For details, see “Screen Settings 3 Ceiling 
Mount” (page 59) under “Setup Menu Settings”.
