Important Safeguards

These safety instructions are to ensure the long life of your projector and to prevent fire

and shock. Please read them carefully and heed all warnings.

Installation

• Do not place the projector in the following conditions:

 On an unstable cart, stand, or table.

 Near water, baths or damp rooms.

 In direct sunlight, near heaters or heat radiating appliances.

 In a dusty, smoky or steamy environment.

 On a sheet of paper or cloth, rugs or carpets.

Important Information

• If you wish to have the projector installed on the ceiling:

 Do not attempt to install the projector yourself.

 The projector must be installed by qualified technicians in order to ensure proper

operation and reduce the risk of bodily injury.

 In addition, the ceiling must be strong enough to support the projector and the in-

stallation must be in accordance with any local building codes.

 Please consult your dealer for more information.

CAUTION:

When shipping the projector, remove the optional lens beforehand. The lens

and the lens shift mechanism may encounter damage caused by improper

handling during transportation.

Place the projector in a horizontal position

Do not put the projector on its side when the lamp is turned on. Doing so may cause

damage to the projector.

CAUTION:

Do not drop the projector on your hand or fingers while lifting the projector to

replace the filters. Doing so could injure your hand or fingers.

Important Information

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 8 inches (20cm) of space be-

tween your projector and a wall.

• Do not try to touch the ventilation outlet on the rear 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 some-

thing should fall into your projector, disconnect it immediately and have the object

removed by 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 ob-

jects 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 elec-

tric shock or fire.

 Do not use any power cables other than the one supplied by NEC.

 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.

Important Information

• Turn off the projector, unplug the power cable and have the projector serviced by

qualified 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.

• Disconnect the power cable and any other cables before carrying the projector.

• Turn off the projector and unplug the power cable if the projector is not to be used for

an extended period of time.

• When using a LAN cable:

 For safety, do not connect to the connector for peripheral device wiring that might

have excessive voltage.

• Turn off the projector and unplug the power cable before cleaning the cabinet or re-

placing the lamp.

CAUTION:

• Always carry your projector by using the carrying handle.

• Do not use the tilt-foot for purposes other than originally intended. Misuses

such as using the tilt foot to carry or hang (from the wall or ceiling) the projec-

tor can cause damage to the projector.

• Do not send the projector in the soft case by parcel delivery service or cargo

shipment. The projector inside the soft case could be damaged.

• Do not unplug the power cable from the wall outlet or projector when the pro-

jector is powered on. Doing so can cause damage to the AC IN connector of

the projector and (or) the prong plug of the power cable.

• To turn off the AC power supply when the projector is powered on, use a

power strip equipped with a switch and a breaker.

• The projector can be unplugged during its cool down period after it is turned

off.

• Do not try to touch the ventilation outlet on the rear as it can become heated

while the projector is turned on and immediately after the projector is turned

off.

• Do not turn off the AC power for 60 seconds after the lamp is turned on and

while the POWER indicator is blinking green. Doing so could cause premature

lamp failure.

• Do not place your hands near the lens opening while shifting the lens. Shifting

the lens could pinch your fingers or hands causing injury.

Important Information

Remote Control Precautions

• Handle the remote control carefully.

• If the remote control gets wet, wipe it dry immediately.

• Avoid excessive heat and humidity.

• Do not heat, take apart, or throw batteries into fire.

• If you will not be using the remote control for a long time, remove the batteries.

• Ensure that you have the batteries' polarity (+/–) aligned correctly.

•

Do not use new and old batteries together, or use different types of batteries together.

• Dispose of used batteries according to your local regulations.

Lamp Replacement

To replace either of the lamps, follow all instructions provided on page 112.

Be sure to replace the lamp when the following is displayed on the screen:

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 dealer for lamp replacement.

Important Lamp Characteristic

The projector has a high-pressure mercury lamp as a light source.

A characteristic of mercury lamps is that brightness gradually decreases with age. Also

repeatedly turning the lamp on and off will increase the possibility of reduced brightness.

CAUTION:

When removing the lamp from a ceiling-mounted projector, make sure that no

one is under the projector. Glass fragments could fall if the lamp has been

burned out.

CAUTION:

In rare cases the lamp bulb may burn out during normal operation and cause

glass dust or shards to be discharged outward from the rear exhaust vent.

Do not inhale or do not touch glass dust or shards. Doing so could result in

injury.

[Important 1] Operating the Lamp Continuously

If using the projector continuously for a long period, use of the menu (OSD) is recom-

mended in order to properly cycle the lamps as described below.

 To use the projector continuously in the dual lamp mode

Allow 2 hours per day of non usage time per lamp. Do this for both lamps at the same

time or for “Lamp 1” and “Lamp 2” at separate 2 hour intervals.

 To use the projector continuously in single lamp mode

Use the two lamps (Lamp 1 and Lamp 2) alternately in a cycle of 24 hours or less.

Allow 2 hours or longer per day of no-use time for each lamp.

Contact your dealer for more details.
