Power Supply
1. 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.
2. Handle the power cable carefully and avoid excessive bending. A
damaged cord can cause electric shock or fire.
3. If the projector is not to be used for an extended period of time,
disconnect the plug from the power outlet.
4. Do not touch the power plug with wet hand. Doing so can cause
electrical shock or fire.
5. Do not touch the power plug during a thunder storm. Doing so
can cause electrical shock or fire.
Cleaning
1. Unplug the projector before cleaning.
2. Clean the cabinet periodically with a damp cloth. If heavily soiled,
use a mild detergent. Never use strong detergents or solvents such
as alcohol or thinner.
3. Use a blower or lens paper to clean the lens, and be careful not to
scratch or mar the lens.
CAUTION
Do not unplug the power cable from the wall outlet under any one of
the following circumstances. Doing so can cause damage to the pro-
jector:
• While the message "Please wait a moment." appears. This mes-
sage will be displayed after the projector is turned off.
• Immediately after the power cable is plugged into the wall outlet
(the POWER indicator has not changed to a steady orange glow).
• Immediately after the cooling fan stops working (The cooling fan
continues to work for 90 seconds (2 minutes in the optional ex-
tended life lamp GT60LPS) after the projector is turned off with the
POWER button).
CAUTION
• Do not try to touch the ventilation outlets as they can become heated
while the projector is turned on.
• Do not put the projector on its side when the lamp is turned on.
Doing so may cause damage to the projector.
• Before shipping this projector, remove the lens and attach the lens
hood cap.
The Lens Shift mechanism may encounter damage caused by im-
proper handling during transportation.
• Do not eject a PC card or LAN card while its data is being ac-
cessed. Doing so can damage your PC card or LAN card.
Lamp Replacement
• To replace the lamp, follow all instructions provided on page 9-2.
• Be sure to replace the lamp when the message "The Lamp has
reached the end of its usable life. Please replace the lamp." ap-
pears. 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 NEC
dealer for lamp replacement.
• Allow a minimum of 90 seconds (2 minutes in the optional extended
life lamp GT60LPS) to elapse after turning off the projector. Then
turn off the main power and disconnect the power cable and allow
60 minutes to cool the projector before replacing the lamp.
• The projector must be operated with two lamp housings installed
regardless of whether or not the lamp is active. Failure to do so
may degrade the performance of the projector such as screen flicker
or loss of lamp life. If one lamp has reached the end of its usable
life, replace it with a new one as soon as possible.
Fire and Shock Precautions
1. Ensure that there is sufficient ventilation and that vents are unob-
structed 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. Allow at least 12 inches (30cm) of space between the outlets
on the left side (when viewed from the front) and the 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 ob-
ject removed by a qualified NEC service personnel.
3. Do not place any liquids on top of your projector.
4. When using a LAN cable:
For safety, do not connect to the connector for peripheral device
wiring that might have excessive Voltage.
CAUTION
• 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 com-
ing out of the lens, can cause unpredictable outcome such as fire
or injury to the eyes.
• Do not cover the lens with the supplied lens hood cap or equiva-
lent 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.
