10°

Fire and Shock Precautions

• Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the build-up of heat inside your projector. Allow at least 4 inches (10cm) of space between your projector and a wall.

• 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.

• 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 project. If something should fall into your projector, disconnect it immediately and have the object removed by a qualified service personnel.

• Do not place any objects on top of the projector.

• Do not touch the power plug during a thunderstorm. Doing so can cause electrical shock or fire.

• The projector is designed to operate on a power supply of 100-240V AC 50/60 Hz. Ensure that your power supply

fits this requirement before attempting to use your projector.

• Do not look into the lens while the projector is on. Serious damage to your eyes could result.

• 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.

• Do not cover the lens with the black 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.

• Do not place any objects, which are easily affected by heat, in front of the projector lens or a projector exhaust vent. Doing so could lead to the object melting or getting your hands burned from the heat that is emitted from the light output and exhaust.

• Handle the power cable carefully. A damaged or frayed power cable can cause electric shock or fire.

- Do not use any power cables than the supplied one.

- Do not bend or tug the power cable excessively.

- Do not place the power cable under the projector, or any heavy object.

- Do not cover the power cable with other soft materials such as rugs.

- Do not heat the power cable

- Do not handle the power plug with wet hands.

• Turn off the projector, unplug the power cable and have the object removed by a qualified NEC service personnel under the following conditions:

- When the power cable or plug is damaged or frayed.

- If liquid has been spilled into the projector, or if it has been exposed to rain or water.

- If the projector does not operate normally when you follow the instructions described in this user's manual.

- If the projector has been dropped or the cabinet has been damaged.

- If the projector exhibits a distinct change in performance, indicating a need for service.

2. Installation and Connections

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 41˚F (5˚C) and 104˚F (40˚C) (Eco mode selected automatically at 95˚F to 104˚F/35˚C to 40˚C).

• 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 when a smaller space is required. Contact your NEC dealer if you need a mirror system. If you're using a mirror system and your image is inverted, use the MENU and SELECT buttons on your projector cabinet or your remote control to correct the orientation. (→ page 44)

2. Installation and Connections

 Making Connections

NOTE: When using with a notebook PC, 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. In most cases the output signal from the notebook PC is not turned on unless connected to the projector before being powered up. * If the screen goes blank while using your remote control, it may be the result of the computer's screen-saver or power

management software.

Enabling the computer’s external display

Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the projector. When using a PC compatible laptop, a combination of function keys will enable/disable the external display. Usually , the combination of the ‘Fn” key along with one of the 12 function keys gets the external display to come on or off. For example, NEC laptops use Fn + F3, while Dell laptops use Fn + F8 key combinations to toggle through external display selections.

Connecting Your PC or Macintosh Computer
