Before turning on your projector or computer, all cables should be connected as described below.
- From the cables provided, locate the desired connection cables (VGA or DVI) and the power cord.
- Connect one end of your VGA or DVI cable to the corresponding input located on the back or side of the projector.
- Connect the other end of the cable to the corresponding port on the back of your computer or laptop. If you're using a Macintosh computer, a Mac signal adapter (often included) may be required.
- Verify that you have a good power source and connect the power cord from the projector to the outlet. Try to avoid extension cords if possible.
- For best results when using a laptop, use the computer's included AC power adapter rather than the laptop battery.
VCR or DVD player
- From the cables provided,locate the RCA audio and video cables or the S-video cable.
- Connect one end of the cables to the audio and video or S-video outputs on the back of the VCR/DVD player.
- Connect the other end of the cables to the projector's audio and video or S-video inputs. The RCA audio and video inputs and outputs are color-coded.
2. Image Adjustments
- Remove the lens cap and put it in the case for safekeeping
- Ensure that all connections are correct and snug.
- Turn the projector on. Some projectors have two power switches: one located near the power cord, and one on top of the projector. Press and release the power/stand-by button.
- Once the start-up image is projected on the screen, turn on your computer or VCR/DVD player.
- If using a laptop computer you may be required to activate the monitor output port. First, locate the function key marked with either a picture of two monitors or the letters "LCD/CRT." On the lower left corner of your keyboard is a key marked "FN." Press and hold this key while you press and release the function key you just located. This should turn on your monitor output port.
- With the image projected on your screen, adjust the focus and the image size. These adjustments are accomplished with the focus/zoom adjustment rings or power focus/zoom buttons if so equipped.
- Neither the front nor rear of the projection screen should be exposed to direct light or sunlight.
- The projector is equipped with ventilation holes. Don't block or place anything near these vents. Internal heat build up may occur, causing image degradation, reduced lamp life or damage to the projector. Air from these vents may be very hot, so keep hands and other objects clear.
- Do ot look into the lens when the lamp is on.
- Shut down the projector by first pressing the stand by/power button and allowing the fan to cool the unit before removing the main power. The fan speed will slow considerably when the unit is cool.
Projector and Lamp Care
Projector Care Tips
- Read the user's manual that came with your projector. It will include operational information exclusive to your projector.
- Become familiar with the unit before your first presentation or event.
- To prolong your lamp's life, always allow your projector to cool completely before turning off or unplugging. Remember that excessive heat can greatly shorten your lamp life. Do not operate your projector in direct sunlight or near a heat source.
- Change filter as specified by your user's manual.
- Never operate the unit without the air filter. Doing so can draw dust in to the optics of the projector, which can be projected on to your image.
- Avoid using your projector in a dusty environment. This can cause damage to the optics of the unit and can void your warranty.
- Store your projector in a cool, dry area. Save the shipping box for safe, secure storage when not in use. If the need arises for you to ship your projector in the future, the original box and packing material is the safest way to pack your unit.
- If projector is mounted to ceiling, be sure the area near the intake fan is kept clean and not in direct line of air or heat vents.
- For optimal image quality, always keep your lens clean. The safest way to clean your lens is with a lens cloth, which can be purchased at a camera store.
Tips to Extend Lamp Life
Lamp life for a projector will vary based on many factors including application, installation, intake of cool air and exhaust of hot air, usage, and proper maintenance. Heat buildup can reduce lamp life and even damage your projector. Here are some tips to help your projector lamps last longer.
- Once you turn on your projector, wait at least five minutes before turning it off to allow the fan to properly cool the unit. After the fan has cooled your projector, you may unplug it and store it as desired.
- Do not obstruct the air intake or exhaust vent. Paper should not be placed on top of a projector, or where vents are located.
- Keep the exhaust vent at least 30cm from any object.
- If the projector is built into a compartment, wall, ceiling or shelf mount, the minimum distance requirement (usually at least 30cm) stated in your owners manual must be maintained.
- Clean the projector's air intake filter every three to six months - or more frequently - based on your operating environment.
- Do not move your projector until the lamp has cooled (about five minutes).
