Cautions needed before the start of WT610/WT615 service

1. How to turn on the power supply with the top cover assy left removed
This model is provided with an additional mode where the power supply is turned on even after the M3 cover and
the connectors have been removed for servicing.
The method of entering the mode is as shown below.

1-1. Short-circuit the test pins of SUB PWB (TP601 and TP602) with a crocodile clip or the like.
1-2. In the Normal state, keep pressing the main unit key Focus+ for more than 10 seconds.

This method is effective in the Normal state or when the power supply is turned ON. In the Power-saving state
or when the AC source is OFF, this action results in the withdrawal from this moel. Therefore, if any examination
is needed, a proper measure has to be taken not to assume the standby state.
(As a proposed method, for example, the Normal state may be fixed based on the menu or a wired remote
control may be used.)

• Normal mode ............................ Power indicator: Orange light/Status indicator: Green light.

• Power-saving mode .................. Power indicator: Orange light/Status indicator: Off.

2. The components of the FIXED MIRROR (PA41) specified below are replaceable.

FIXED MIRROR M3 (PA27) (12JS6721)
FIXED MIRROR M4 (PA27) (12JS6731)
MIRROR COVER F (PA41) (24FT9491)
MIRROR COVER R (PA41) (24FT9501)

Components cannot be replaced for those other than the 4 items specified above.
Replacement is possible only for the BASE ENGINE SASSY (82K15111).
(The junction adjustment for the optical system is possible only in the manufacturer’s factory. This action cannot
be taken at the service sector.)

Similarly, the replacement of the DMD Chip is impossible. Therefore, this replacement is possible by replacing
the Base Engine SASSY (82K15111).

SAFETY PRECAUTIONS

During servicing carefully observe the following.

1. OBSERVE ALL PRECAUTIONS

Items and locations that require special care during serv­icing, such as the cabinet, chassis, and parts are labelled
with individual safety instructions. Carefully comply with
these instructions and all precautions in the instruction
manual.

2. BE CAREFUL OF ELECTRIC SHOCK

The chassis carries an AC voltage. If you touch the
chassis while it is still alive, you will get a severe shock.
If you think the chassis is alive, use an isolating
transformer or gloves, or pull out the plug before
replacing any parts.

3. USE SPECIFIED PARTS

The components have been chosen for minimum
flammability and for specific levels of resistance value
and withstand voltage. Replacement parts must match
these original specifications. Parts whose specifications
are particularly vital to safe use and maintenance of the
set are marked on the circuit diagrams and parts list.
Substitution of these parts can be dangerous for you
and the customer, so use only specified parts.

4. REMOUNT ALL PARTS AND RECONNECT ALL
WIRES AS ORIGINALLY INSTALLED

For safety, insulating tape and tubes are used
throughout, but some lift-off parts on the printed wiring
board require special attention.
All wires are positioned away from high-temperature and
high-voltage parts, and, if removed for servicing, they
must be retuned precisely to their original positions.

5. LAMP

Be very careful of the lamp because it generates high
heat while it is used at high voltage. When replacing
the bulb, make sure it is cool enough.

6. MIRROR

Do not look into the mirror during projection. This
important to avoid damage to the eyes.

7. SERVICING

At the time of repair or inspection services, use an earth
band (wrist band), without fail.

8. RUN A COMPLETE SAFETY CHECK AT THE
COMPLETION OF SERVICING

After completion of servicing, confirm that all screws,
parts, and wiring, removed or disconnected for servicing,
have been returned to their original positions. Also
examine if the serviced sections and peripheral areas
have suffered from any deterioration as a result of
servicing. In addition, check insulation between external
metallic parts and blades of wall-outlet plugs. This
examination is indispensable in confirming complete
establishment of safety.

(Insulation check)
Pull out a plug from a wall outlet to disconnect the
connection cable. Then turn on the POWER switch.
Use a 500V megger (Note 2) and confirm that the
insulation resistance is 1MΩ or more between each
terminal of the plug and exposed external metal (Note

1). If the measured value is below the specified level,
then it is necessary to inspect and fix the set.

(Note 1)

Exposed external metal....RGB input terminals, control

terminals, etc.
(Note 2)
If a 500V megger is not available for an unavoidable
reason, then use a circuit tester or the like for inspection.

Screens Suited

• The projector can accommdate 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).

40"-100"

• Use a panel or tension type screen that has a flat surface.

Recommended

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.

• View the screen directly from the side so that it is perfectly vertical.

Recommended

A slanted screen will result in increased keystone distortion.

90˚

• In using this projector, increasing the screen size will move the projection position upward. To
accommodate this, please use a screen that can be raised and lowered to a given screen
position. See page E-2 for information about the positioning relationships between the screen
and this projector.

• High gain type screens are not optimal for use with this projector. 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 manufacturers.

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

• Due to the projection angle of the projector, 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.

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

NOTE: Immediately after turning on the projector, screen flicker may occur. This is not a fault. Wait 3 to 5 minutes until the lamp
lighting is stabilized.

•When the Lamp mode is set to Eco, the Lamp indicator will light green.

• If one of the following things happens, the projector will not turn on.

- If the internal temperature of the projector is too high, the projector detects abnormal high temperature. In this

condition the projector will not turn on to protect the internal system. If this happens, wait for the projector's
internal components to cool down.

-When the lamp reaches its end of usable life, the projector will not turn on. If this happens, replace the lamp.

- If the lamp fails to light, and if the STATUS indicator flashes on and off in a cycle of six times, wait a full minute and

then turn on the power.

-When the mirror cover is closed.

- If the temperature sensor detects excessive heat in the bottom of the mirror or in the light path, the projector will

not turn on. Remove objects such as dust from the bottom of the mirror.

- The projector has a sensor which detects an object in front of the largest mirror or in the light path. If the sensor

detects any object, the projector will not turn on. Remove the object.

- 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.

• Immediately after turning on the projector and displaying an image, you cannot turn off the projector for 60 seconds.

 Adjusting the Position and Size of the Projected Image (Focus Adjustments)

• After turning on the power, projected images may flicker for 3 to 5 minutes until the lamp lighting is stabilized.

Also after turning on the projector, the picture position may be slightly changed.
Wait 10 minutes until the light status and projected images become stable.

• If the screen is tilted vertically or horizontally, keystone distortion becomes large. Proceed with the following

steps to correctly set up the projector and the screen.

1. Check whether the screen is set up to be vertical by viewing it from

the side.

• Pincushion or barrel distortion in this projector
The amount of pincushion and barrel distortion in this projector is 2% or less (TV distortion) in each of the

horizontal and vertical directions (for screen sizes of 40 inches to 100 inches).
As an example, the amount of distortion with a screen size of 60 inches (121.9 cm/48.0” W x 91.4 cm/36.0” H) is

within approximately 12 mm/0.47” in the horizontal direction and within approximately 9 mm/0.35” in the vertical
direction. When this projector is used with a 60-inch screen size, the amount of pincushion and barrel distortion
is at a minimum.

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 mirror or the light source 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

mirror is extensive, therefore any kind of abnormal objects that can redirect light coming out of the mirror, can
cause unpredictable outcome such as fire or injury to the eyes.

6. Do not block the light path between the light source and the final mirror with any objects. Doing so could cause

the object to catch on fire.

7. 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.

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.

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

12. 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 try to touch the ventilation openings on the both sides as it can become heated while the projector is
turned on.

• Do not attempt to move or carry the projector using the mirror cover.
Doing so can result in the projector overturning and causing injury. Using the two side handles is the proper

way to move the projector.
When carrying or transporting the projector, close and lock the mirror cover with the mirror cover lock switch.

• The carrying handles are designed for the purpose of carrying the projector. Do not hang from the projector by
the carrying handles in a ceiling mounted installation. Doing so may result in the carrying handles separating
from the unit or the projector may separate from the mount resulting in personal injury.

• Select [High] in Fan mode if you continue to use the projector for consecutive days. (From the menu, select
[Setup] → [Options] → [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 projector's lamp is on.
* While the cooling fans are running. (The cooling fans continue to work for 90 seconds after the projector is

turned off).

* While the PC CARD Access Indicator lights. Doing so can damage your PC memory card.

2. Installation and Connections

Screens Suited

• The projector can accommdate 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).

40"-100"

• Use a panel or tension type screen that has a flat surface.

Recommended

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.

• View the screen directly from the side so that it is perfectly vertical.

Recommended

A slanted screen will result in increased keystone distortion.

90˚

• In using this projector, increasing the screen size will move the projection position upward. To
accommodate this, please use a screen that can be raised and lowered to a given screen
position. See page 16 for information about the positioning relationships between the screen
and this projector.

• High gain type screens are not optimal for use with this projector. 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 manufacturers.

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

• Due to the projection angle of the projector, 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.

With the LAN connection, two features are available: Projector control and Picture transmission.

Projector control feature

With the wired or wireless LAN connection, you can control (power on/off, input select, etc.) and receive information
from the projector over the network using a computer. The following two methods are available:

* Using the HTTP Server feature on the projector. See page 63.
* Using PC Control Utility 3.0 from the supplied User Supportware 2 CD-ROM.

Picture transmission feature

With the wired or wireless LAN connection, you can send images and slides from a personal computer to the projector
which then can be projected on the screen. The following two methods are available:

* Using Image Express Utility 2.0 from the supplied User Supportware 2 CD-ROM.
* Using Ulead Photo Explore 8.0 from the supplied User Supportware 2 CD-ROM.

With the USB mouse connected to the projector, you can also operate the desktop screen on your Windows PC
connected to the LAN or the wireless LAN.

* Using Desktop Control Utility 1.0 from the supplied User Supportware 2 CD-ROM.

NOTE: Immediately after turning on the projector, screen flicker may occur. This is not a fault. Wait 3 to 5 minutes until the lamp
lighting is stabilized.

• When the Lamp mode is set to Eco, the Lamp indicator will light green.

• If one of the following things happens, the projector will not turn on.

- If the internal temperature of the projector is too high, the projector detects abnormal high temperature. In this

condition the projector will not turn on to protect the internal system. If this happens, wait for the projector's
internal components to cool down.

- When the lamp reaches its end of usable life, the projector will not turn on. If this happens, replace the lamp. See

page 134.

- If the lamp fails to light, and if the STATUS indicator flashes on and off in a cycle of six times, wait a full minute and

then turn on the power.

- When the mirror cover is closed.

- If the temperature sensor detects excessive heat in the bottom of the mirror or in the light path, the projector will

not turn on. Remove objects such as dust from the bottom of the mirror.

- The projector has a sensor which detects an object in front of the largest mirror or in the light path. If the sensor

detects any object, the projector will not turn on. Remove the object.

- 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.

• Immediately after turning on the projector and displaying an image, you cannot turn off the projector for 60 seconds.
