SVGAA type of video signal with a resolution of 800 (horizontal) × 600 (vertical) dots which is used by IBM PC/AT-compatible computers.
S-VideoA video signal which has the luminance component and color component separated in order to provide better image quality. 
It refers to images which consist of two independent signals: Y (luminance signal), and C (color signal).
SXGAA type of video signal with a resolution of 1280 (horizontal) × 1024 (vertical) dots which is used by IBM PC/AT-compatible computers.
Sync (synchronization)The signals output from computers and RGB video equipment have a specific frequency. If the projector frequency does not match this 
frequency, the resulting images will not be of a good quality. The process of matching the phases of these signals (the relative position of the 
crests and troughs in the signal) is called synchronization. If the signals are not synchronized, problems such as flickering, blurriness and 
horizontal interference can occur.
Tr a c k i n gThe signals output from computers and RGB video equipment have a specific frequency. If the projector frequency does not match this 
frequency, the resulting images will not be of a good quality. The process of matching the frequency of these signals (the number of crests in 
the signal) is called tracking. If tracking is not carried out correctly, wide vertical stripes will appear in the projected images.
USBAn abbreviation for Universal Serial Bus. USB is an interface for connecting personal computers to peripheral devices which only support 
relatively low data transmission speeds.
VGAA type of video signal with a resolution of 640 (horizontal) × 480 (vertical) dots which is used by IBM PC/AT-compatible computers.
XGAA type of video signal with a resolution of 1024 (horizontal) × 768 (vertical) dots which is used by IBM PC/AT-compatible computers.

Command List
When a power on command is sent to the projector, the power will turn on and 
the projector will change to warm-up mode. When the power has turned on, a 
colon : (3Ah) will be returned.
When the projector executes a command, it returns a : and waits for the next 
command to be sent.
If command processing terminates with an error, the projector outputs an 
error message and then returns the : code.
* When issuing any of the above commands, tack a Carriage Return (CR) code (0Dh) 
on to the end.

							69Important Safety Instructions 
◗The lamp is fragile, and can easily break. If the lamp breaks, handle the 
projector with extreme care to avoid injury from broken glass, and contact 
Epson for repairs (see page 57
). Particular care should be taken when the 
projector is installed to a ceiling, as small pieces of glass may fall down 
when the lamp cover is removed. Be very careful not to allow such pieces 
of glass to get into the eyes or mouth.
◗Material or paper may get stuck against the air filter underneath the 
projector while it is in use. Remove anything from underneath the projector 
that might get stuck against the air filter in this way.
◗Never try to remove the lamp immediately after use. Doing so will result in 
serious burns. Before removing the lamp, turn off the power supply and 
wait the time specified in the User’s Guide to allow the lamp to cool 
completely.
◗A mercury lamp with high internal pressure is used as the projectors light 
source. Mercury lamps may make a loud noise when they break. Handle 
the lamp with extreme care while observing the following. If the following 
points are not observed, injury or poisoning may result.
◗Do not damage the lamp or subject it to any impacts.
◗Do not use the lamp after the lamp replacement period has elapsed. 
Once the lamp replacement period has elapsed, the possibility of the 
lamp breaking becomes greater. When the lamp replacement message 
appears, replace the lamp with a new one as soon as possible.
◗The gases inside mercury lamps contain mercury vapor. If the lamp 
breaks, immediately ventilate the room to prevent the gases that are 
released when the lamp breaks from being inhaled or coming into 
contact with the eyes or mouth.
◗Do not bring your face close to the projector while it is in use, in order to 
prevent the gases that are released when the lamp breaks from being 
inhaled or coming into contact with the eyes or mouth.
◗If the lamp breaks and needs to be replaced with a new lamp, contact 
Epson for information on replacement (see page 57
). If the lamp 
breaks, pieces of broken glass may get scattered around inside the 
projector.◗Particular care should be taken when the projector is installed to a 
ceiling, as small pieces of glass may fall down when the lamp cover is 
removed. If cleaning the projector or replacing the lamp yourself, be 
very careful not to allow such pieces of glass to get into the eyes or 
mouth. In addition, consult your local regulations regarding proper 
disposal and do not place in the trash. 
◗If the lamp breaks and gas from the lamp or fragments of broken glass are 
inhaled or get into the eyes or mouth, or if any other ill effects are noticed, 
immediately seek medical advice.
