Frequently Asked Questions - WT600 NEC

How to clean the mirror of the NEC WT600 projector?

Gently wipe the mirror surface with the supplied cleaning cloth to remove fingerprints. Do not use abrasive cleaners or solvents. Refer to page 7-2 of the user manual for details.

What is the projection distance for a 60-inch screen?

For a 60-inch 4:3 screen, the projection distance (C) is approx. 263 mm (10.4 inches). The height (D) from the bottom of the projector to the bottom of the screen is approx. 482 mm (19.0 inches).

How to correct keystone distortion?

First, ensure the screen is perfectly vertical and the projector is level. Use the FOCUS buttons to focus, which also corrects vertical keystone distortion. If the problem persists, adjust the screen tilt or projector feet.

What to do if the projected image is blurry?

Adjust focus using the FOCUS buttons. Ensure the distance between the projector and screen is within the recommended range. If the projector was moved from a cold to a warm place, wait until there is no condensation on the mirror before turning it on.

How to replace the projector lamp?

When the LAMP indicator flashes red or stays on, the lamp needs replacement. Turn off the projector, unplug it, then remove the lamp cover (refer to user manual page 7-1). Use a genuine NEC replacement lamp.

What to do if the projector does not turn on?

Check that the power cord is plugged in and the main power switch is in the ON (I) position. Make sure the lamp cover is properly installed. If the STATUS indicator flashes red (1 cycle), the mirror cover may be closed or the lamp is defective.

What types of screens are compatible with the NEC WT600?

Use panel-type or flat surface screens from 40 to 100 inches. Avoid pull-down or warped screens. High-gain screens are not recommended. For best quality, use a low-gain screen (about 1).

How to use the 3D Reform function to correct distortions?

Press the 3D REFORM button on the projector or remote. The 'Pincushion' screen appears. Use SELECT ▲▼◄► buttons to adjust the right/left, top, and bottom overhangs. Confirm with ENTER. Note that if 'Keystone' has been set, disable it first.

What do the different indicator lights mean?

POWER indicator: solid green (on), solid orange (standby), blinking green (ready to turn on), blinking orange (cooling). STATUS indicator: blinking red indicates an error (cover, temperature, power, fan, lamp). See the table on page F-13 for details.

How to connect a computer to the projector?

Use the supplied 15-pin RGB signal cable. For older Macintosh, use an adapter. Turn off all equipment before connecting. Then plug in the power cable. For digital DVI signal, use a DVI-D cable (supplied) and follow the power-on sequence (projector first).

WARNING

• Do not set up the projector, the screen or stand in a place that is not level or in an unstable location. Doing so may result in the screen falling over or the projector falling which may result in injury.
• When setting up the projector on the stand, first secure the top plate in a level condition. When the top plate is set at an angle, the projector may fall resulting in injury.
• Use a stand that can fully support the weight of the projector (which for this unit is approximately 13lbs / 5.9kg ). Failing to do so may result in the projector falling and causing injury.

Screens Suited for the WT600

• The unit can accommodate screen sizes from 40^ (81.3 cm/32.0" W × 61.0 cm/24.0" H) to 100 inch (203.2 cm/80.0" W × 152.4 cm/60.0" H).

• Use a panel or tension type screen that has a flat surface. Do not use roll type screens and other screens that bend or form a wavy surface easily. Doing so will result in increased distortion of the projected image.

Recommended

Not recommended

View the screen directly from the side so that it is perfectly vertical. A slanted screen will result in increased keystone distortion.

Recommended

Not recommended

• In using this unit, increasing the screen size will move the projection position upward. To accommodate this, please use a screen that has higher and lower positioning adjustment. See Page 4 for information about the positioning relationships between the screen and this unit.

Recommended

• High gain type screens are not optimal for use with this unit. The lower the screen gain (i.e., screen gain on the order of 1), the better the appearance of the projected image. For more information about screen gain, consult catalogs from screen makers.

Not recommended

• Screen frames or pen shelves that protrude from the front of the screen surface may block some of the light from the projector.

Not recommended

• Due to the projection angle of the unit, many standard rear projection screens may produce uneven brightness, hot spotting or not produce maximum brightness to the viewer. For more details utilizing rear projection screens and their applications with this projector, please contact your NEC dealer.

Not optimal

• Controlled ambient light environments will allow for an image of higher contrast and depth to be displayed.

Not recommended

• Screens with a soiled, scratched, or discolored area will not produce a clean image. Care should be used in the handling of the screen.

Not recommended

Stands Suited for the WT600

• In using this unit, increasing the screen size will move the projection position upward. To accommodate this, please use a stand that has a height positioning adjustment. See Page E-4 for information about the positioning relationships between the screen and this unit.

Recommended

• Use a stand that will allow this unit to be set up in a level condition. Turn the foot of this unit and adjust so that the unit is level.

Recommended

Ambient environmental condition

• Do not place the screen near vents.

Air blow hits the screen, causing the projected image to ripple.

• Do not illuminate the projector with strong light source such as halogen lamp.

Doing so can cause the object detection sensor to malfunction, resulting in the projector not turning on.
