Digital+Projector


 * Find the numbers below to describe each function on the projector's control panel

1.** To power on the projector press the power button on top of the projector. The small LED light next to the power button will glow Amber when the projector is receiving power but is not powered on. Press the button and the light will blink green. The blinking will stop and the light will turn a solid green as soon as the lamp is warmed up and an image is visible. The two other LED lights on the top will warn you when the projector is having problems.


 * 2.** The Temp light will warn you when the lamp temperature is too high. This is caused by a constriction in the cooling air flow that moves over the lamp. An internal fan pulls air from the bottom of the projector and over the lamp to keep it cool. A filter resides underneath the lens to keep dust from entering inside the machine. If this filter becomes covered in dust it may need to be cleaned. You can remove the filter and wipe the dust from with your hand. Reinsert the filter and you will notice the fan running smoother and the projector getting cooler. The Temp light will then go out. When shutting down the projector please allow the fan to wind all the way down before unplugging the cart. This will ensure the proper cooling of the lamp and avoid a premature end of life of the product.


 * 3.** Lamp blinks when the lamp is nearing its end of life cycle. The light will start blinking once the internal calendar reaches a certain number of lamp hours used. A message will also appear on the projected image. Seeing the message and the blinking light does not mean the lamp will immediately stop working. The lamp my still run for several more hours before it burns out. Alert the techco when you see the light. He/she will determine whether it is in need of replacement.


 * 4.** Once the projector comes on it will start cycling through all the different sources connected looking for the one sending a signal. The projector has four different inputs. Only two devices connected to the projector, the VCR/DVD and Document Camera. The VCR/DVD is connected through Video and Document Camera is connected through Computer 1. If this has been chanted please contact the techco. There is no reason for you or any students to disconnect or change these connections. They are in place for your convenience. The projector starts with the Computer inputs as default then cycles down through the to the Video inputs, but the system will automatically look for the first broadcasting signal. If the image projected is not the one you are looking for then press the Source Search button to change the other images.

If the image on the screen does not fill the entire screen or looks askew or blurry, here are the steps to solve those issues.

Askew
If your image looks crooked on the screen you can fix this by lining up the cart directly in front of the screen by running the cart perpendicular to it. Then adjust the projector by raising the front foot so that the image is raised up on the screen. To accomplish this you need to either press down the button to let the foot fall to the cart or twist the foot for a more exact set up. If the image still looks like it is leaning to the left or right you can adjust the rear foot by twisting it up or down. Once you find peace with these settings you should not have to reset them, unless they get moved.


 * 5.** If the image is leaning forward or backward on the screen you will need to adjust the keystone. See below:

The projector has an automatic keystone that adjusts when the image is first projected. If this needs to be tweaked use the keystone buttons on the top of the projector to set straighten the image.

Filling The Screen
If the image only takes up a portion of the screen you can do one of two things. One, roll the cart back from the screen to expand the size of the image, or two, using the zoom knob **(6)** located behind the lens you can zoom the image out or in to expand it on the screen. If you wan to zoom it all the way out you can move the cart closer to the screen without having it in the way of any desks.

Blur
To remove any blur adjust the focus knob **(7)** located in the front of the zoom knob. This will make the image clear and easy to see.

Once the projector is set you may not need to make any more major adjustments again. Just wheel the cart into place when you want to use it and you will be good to go. << A/V Cart Set Up Document Camera >>
