Important 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 4 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.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.

8.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.

9.Handle the power cable carefully and avoid excessive bending. A damaged cord can cause electric shock or fire.

10.If the projector is not to be used for an extended period of time, disconnect the plug from the power outlet.

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

12.Do not handle the power plug with wet hands.

CAUTION

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.

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.

When carrying the projector by the carrying handle, make sure the two screws that attach the carrying handle to the projector cabinet are tight. (VT676/VT670/VT470 only)

Insufficient tightening of the two screws could result in the projector falling and causing injury.

Do not send the projector in the soft carrying case by parcel delivery service or cargo shipment. The projector inside the soft carrying case could be damaged.

Select [High] in Fan mode if you continue to use the projector for consecutive days. (From the menu, select [Advanced] → [Fan Mode] → [High].)

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:

*While the Hour Glass icon appears.

*While the cooling fans are running. (The cooling fans continue to work for 30 seconds after the projector is turned off).
