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. The projector is designed to operate on a power supply of 100--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.
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 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.
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.)
Enable High-Speed Fan mode if you continue to use the projector for consecutive days. (From the menu,
select [Setup] [Page 4] [Fan Mode].)
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 10 seconds after the projector is
turned off).
