CAUTION Do no use the tilt-foot for purposes other than originally intended. Misuses such as gripping the tilt-foot or hanging on the wall can cause damage to the projector. Do not send the projector in the soft case by parcel delivery service or cargo shipment. The projector inside the soft case could be damaged. When carrying the projector by the carrying handle, make sure the two screws that attach the carrying handle to the projector cabinet are tight. Insufficient tightening of the two screws could result in the projector falling and causing injury. Select [High] in Fan mode if you continue to use the projector for consecutive days. (From the menu, select [Setup] [Options] [Fan Mode] [High].) Do not turn off the AC power by pressing the main power switch or by unplugging the power cable when the projector is powered on. Do not turn off the AC power for 60 seconds after the lamp is turned on and while the POWER indicator is blinking green.Doing so could cause premature lamp failure.
Remote Control Precautions
Handle the remote control carefully. If the remote control gets wet, wipe it dry immediately. Avoid excessive heat and humidity. Do not heat, take apart, or throw batteries into fire. If you will not be using the remote control for a long time,remove the batteries. Ensure that you have the batteries polarity (+/-) aligned correctly. Do not use new and old batteries together, or use different types of batteries together. Dispose of used batteries according to your local regulations.

Lamp Replacement

To replace the lamp, follow all instructions provided on page 51. Be sure to replace the lamp when the message [The lamp has reached the end of its usable life. Please replace the lamp.] appears. If you continue to use the lamp after the lamp has reached the end of its usable life, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp case. Do not touch them as the pieces of glass may cause injury. If this happens, contact your dealer for lamp replacement.

A Lamp Characteristic

The projector has a high-pressure mercury lamp as a light source. A lamp has a characteristic that its brightness gradually decreases with age. Also repeatedly turning the lamp on and off will increase the possibility of its lower brightness.
CAUTION: When removing the lamp from a ceiling-mounted projector, make sure that no one is under the projector. Glass fragments could fall if the lamp has been burned out.

To wall outlet

Make sure that the prongs are fully inserted into both the AC IN and the wall outlet.
CAUTION: Do not try to touch the ventilation outlet on the left front (when seen from the front) as it can become heated while the projector is turned on and immediately after the projector is turned off.
CAUTION: Do not turn off the AC power by pressing the main power switch or by unplugging the power cable when the projector is powered on. Doing so can cause damage to the projector.
TIP: The projector can be turned off (by either the main power switch or by unplugging the power cable) during its cool down period after it is turned off using the remote control or via the power button on the control panel.
3. Projecting an Image (Basic Operation)
This section describes how to turn on the projector and to project a picture onto the screen.

Turning on the Projector

NOTE: The projector has two power switches: a main power switch and a POWER (ON/STAND BY) button (POWER ON and OFF on the remote control). When plugging in or unplugging the supplied power cable, make sure that the main power switch is pushed to the off () position. Failure to do so may cause damage to the projector.

NOTE: Immediately after turning on the projector, screen flicker may occur. This is normal. Wait 3 to 5 minutes until the lamp lighting is stabilized.
When the Lamp mode is set to Eco, the LAMP indicator will light green. If one of the following things happens, the projector will not turn on. If the internal temperature of the projector is too high, the projector detects abnormal high temperature. In this condition the projector will not turn on to protect the internal system. If this happens, wait for the projector's internal components to cool down. When the lamp reaches its end of usable life, the projector will not turn on. If this happens, replace the lamp. If the lamp fails to light, and if the STATUS indicator flashes on and off in a cycle of six times, wait a full minute and then turn on the power.

Selecting a Source

Selecting the computer or video source
NOTE: Turn on the computer or VCR connected to the projector.

Adjustable Tilt Foot Button
2. Push and hold the Adjustable Tilt Foot Button on the front of the projector to extend the adjustable tilt foot. 3. Lower the front of the projector to the desired height. 4. Release the Adjustable Tilt Foot Button to lock the Adjustable tilt foot. There is approximately 10 degrees (up) of adjustment for the front of the projector. Adjusting the height of a projected image or changing projection angle will run the Auto Keystone correction function to quickly correct the vertical distortion. The "Keystone" screen will be displayed. For operating the "Keystone" screen, see " Correcting Keystone Distortion" on page 24. The rear foot height can be adjusted up to 0.4 inch/10 mm. Rotate the rear foot to the desired height in order to square the image on the projection surface, but the vertical distance from the bottom to the desk or floor should be 0.4 inch /10mm to make the projector horizontal on the flat surface. NOTE: If you rotate the rear foot too much, it will come off from the bottom.

CAUTION: Do not use the tilt-foot for purposes other than originally intended. Misuses such as using the tilt foot to carry or hang (from the wall or ceiling) the projector can cause damage to the projector.

Common Problems & Solutions ( "Power/Status/Lamp Indicator" on page 54.) Problem Does not turn on Check These Items Check that the power cable is plugged in and that the power button on the projector cabinet or the remote control is on. ( pages 18 and 19) Ensure that the lamp cover is installed correctly. ( page 52) Check to see if the projector has overheated. If there is insufficient ventilation around the projector or if the room where you are presenting is particularly warm, move the projector to a cooler location. Check to see if the lamp usage exceeds 2100* hours (up to 3100* hours : Eco mode). If so, replace the lamp. After replacing the lamp, reset the lamp hours used. ( page 48) * VT58 and VT48: 3100 hours (up to 4100 hours in Eco mode) The lamp may fail to light. Wait a full minute and then turn on the power again. Ensure that the Power Management or Off Timer is off. ( page 45) Use the VIDEO, the S-VIDEO or the COMPUTER button on the remote control to select your source (Computer, Video or S-Video). ( page 21) If there is still no picture, press the button again. Ensure your cables are connected properly. Use menus to adjust the brightness and contrast. ( page 41) Remove the lens cap. Reset the settings or adjustments to factory preset levels using the [Reset] in the Menu. ( page 48) Enter your registered keyword if the Security function is enabled. ( page 30) Be sure to connect the projector and notebook PC while the projector is in standby mode and before turning on the power to the notebook PC.
