a. Do not attempt to install the projector yourself. b. The projector must be installed by qualified technicians in order to ensure proper operation and reduce the risk of bodily injury. c. In addition, the ceiling must be strong enough to support the projector and the installation must be in accordance with any local building codes. d. Please consult your dealer for more information.
Fire and Shock Precautions
1. Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the build-up of heat inside your projector. Allow at least 3 inches (10 cm) of space between your projector and a wall. 2. Prevent foreign objects such as paper clips and bits of paper from falling into your projector. Do not attempt to retrieve any objects that might fall into your projector. Do not insert any metal objects such as a wire or screwdriver into your projector. If something should fall into your projector, disconnect it immediately and have the object removed by a qualified NEC service personnel. 3. Do not place any liquids on top of your projector. 4. Do not look into the lens while the projector is on. Serious damage to your eyes could result. 5. Keep any items such as magnifying glass out of the light path of the projector. The light being projected from the lens is extensive, therefore any kind of abnormal objects that can redirect light coming out of the lens, can cause unpredictable outcome such as fire or injury to the eyes. 6. Do not cover the lens with the supplied lens cap or equivalent while the projector is on. Doing so can lead to melting of the cap and possibly burning your hands due to the heat emitted from the light output. 7. The projector is designed to operate on a power supply of 100-120 or 200-240 V 50/60 Hz AC. Ensure that your power supply fits this requirement before attempting to use your projector. 8. Handle the power cable carefully and avoid excessive bending. A damaged cord can cause electric shock or fire. 9. If the projector is not to be used for an extended period of time, disconnect the plug from the power outlet. 10. Do not touch the power plug during a thunderstorm. Doing so can cause electrical shock or fire.
Allow a minimum of 60 seconds to elapse after turning off the projector. Then turn off the main power switch, disconnect the power cable and allow 60 minutes to cool the projector before replacing the lamp.

What's in the Box?

Make sure your box contains everything listed. If any pieces are missing, contact your dealer. Please save the original box and packing materials if you ever need to ship your VT660K/VT560/VT465 Projector.

CAUTION
1. Do not try to touch the ventilation outlet on the left side (when seen from the front) as it can become heated while the projector is turned on. 2. 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. 3. 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. 4. Do not send the soft carrying case by parcel delivery service or cargo shipment. The projector inside the soft carrying case could be damaged. (However, it is possible to use it as a carriercase on board.) 5. Enable High-Speed Fan mode if you continue to use the projector for consecutive days. (From the menu, select [Advanced] [High Speed Fan Mode].) 6. Do not unplug the power cable from the wall outlet under any one of the following circumstances. Doing so can cause damage to the projector:

WARNING * Installing your projector on the ceiling must be done by a qualified technician. Contact your NEC dealer for more information. * Do not attempt to install the projector yourself. Only use your projector on a solid, level surface. If the projector falls to the ground, you can be injured and the projector severely damaged. Do not use the projector where temperatures vary greatly. The projector must be used at temperatures between 32F (0C) and 95F (35C). Do not expose the projector to moisture, dust, or smoke. This will harm the screen image. Ensure that you have adequate ventilation around your projector so heat can dissipate. Do not cover the vents on the side or the front of the projector.

Reflecting the Image

Using a mirror to reflect your projector's image enables you to enjoy a much larger image. Contact your NEC dealer if you need a mirror. If you're using a mirror and your image is inverted, use the MENU and SELECT buttons on your projector cabinet or your remote control to correct the orientation. (See page E-27.)

4. Lower the front of the projector to the desired height (max. 40mm/ 1.6) and release the Adjustable Tilt Foot Lever to lock the Adjustable tilt foot. There is approximately 10 degrees of up and down adjustment for the front of the projector.
CAUTION Do not 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. Zoom Use the ZOOM lever to finely adjust the image size on the screen.
2. Turn off the Auto Keystone function.
Use the SELECT H button to select Image and then press the SELECT E button. The Auto Keystone will be displayed. Press the SELECT E to select Off.

CAUTION Do not use a lamp other than the NEC replacement lamp (VT60LP). Order this from your NEC dealer.

Replacing the Lamp

After your lamp has been operating for 2000 hours (up to 3000 hours in Eco mode) or longer, the LAMP indicator in the cabinet will blink red and the message will appear. Even though the lamp may still be working, replace it at 2000 (up to 3000 hours in Eco mode) hours to maintain optimal projector performance. CAUTION DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off, wait 60 seconds, turn off the main power switch and then disconnect the power cable. Allow at least one hour for the lamp to cool before handling. DO NOT REMOVE ANY SCREWS except the lamp cover screw and two lamp case screws. You could receive an electric shock. The projector will turn off and go into stand by mode after 2100 (up to 3100 hours in Eco mode) hours of service. If this happens, be sure to replace the lamp. If you continue to use the lamp after 2000 hours (up to 3000 hours in Eco mode) of use, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp case.
