Correcting the Projected Image Using Screen Fit (EB-1925W/1915 Only)

This projector (EB-1925W/1915) is equipped with the following two functions for automatically correcting the projected image.

• Auto H/V-Keystone

When the projector senses any movement, for example, when it is moved, repositioned or tilted, it automatically corrects vertical and horizontal keystone distortions and focus problems. This function of the projector is called Auto H/V-Keystone. When the projector remains still for about two seconds after it sensed a movement, it displays a screen for adjustment and then automatically corrects the projected image.

• Auto H/V-Keystone only works when Extended menu -

• Screen Fit

Screen Fit is a function that corrects the projected image so that it aligns with the frame (outer border) of the screen, white board and the like. By pressing the [Screen Fit] button on the remote control or the control panel, the projected image is fitted into the screen, and keystone correction and focus adjustments are performed automatically.

Projection from the Configuration menu is set to Front. s p.58

• If you do not want to use the Auto H/V-Keystone function, set Configuration menu - Settings menu - Keystone - H/V-Keystone

- Auto H/V-Keystone to Off.s p.56

Quick Start Guide

The following are the conditions for correcting the projected image using Screen Fit.

Screen size: less than or equal to 100"

Distance between projector and screen: approx. 1.0 to 3.5 m

Correction angle: approx 20˚ right and left/approx. 30˚ up and down

• If you exceed the above mentioned range, the projected image

cannot be corrected properly. Correct the projected image manually. Also, depending on the combination of horizontal and vertical angles, the range of correction may be narrower than the above mentioned values.

• Screen Fit does not function if the projector is suspended from a ceiling. Correct the projected image manually.

This section explains how to correct the projected image using Screen Fit.

Correcting the Projected Image Using Screen Fit (EB-1925W/1915 Only)

Procedure

Press the [Screen Fit] button on the remote control or the control panel.

Using the Remote Control Using the Control panel

When the following message box appears, move the projector to adjust the position of the projected image, so that the message box is at the center of the screen.

Adjust the Zoom ring so that the projected area (defined by outer white border line) is bigger than the screen frame.

If the projected area is still not larger than the frame even after adjusting the Zoom ring to its maximum size, try moving the projector further away from the screen. (If this causes the message box moves away from the center of the screen, adjust it so that it is centered again.)

Press the [Screen Fit] button again.

After the adjustment screen appears, the projected image is corrected according to the

Aspect Ratiog of the inputted image.

Correction cannot be performed unless the message box fits within the screen frame. If you cannot make the message box fit inside the screen frame even after adjusting the projector position or the Zoom ring, correct the projected image manually.

Once the adjustment screen appears, do not move the projector or block the image. The projected image will not be corrected properly

Correcting the Projected Image Using Screen Fit (EB-1925W/1915 Only)

After the correction is performed, the following message appears. To exit the correction menu, press the [Esc button] on the remote control or the control panel to clear the message. To fine-tune the projected image after it has been corrected,

make the adjustments using the [

on the control panel.

If no operation is performed, the message closes after about 5 seconds.

After Screen Fit is executed, Keystone from the Configuration menu is set to Quick Corner. After this, any correction of the

projected image using [

control panel will be done through the Quick Corner function.

• Screen Fit corrects the projected image when it detects two or more sides inside the projected area, and aligns with the detected frame. For example, when projecting onto a wide screen in a small room, you can make corrections by fitting the top and bottom sides of the screen into the projected area.

• Screen Fit may not work well in dark environment, such

as a room with lights turned off. In this case, make the room brighter, then try executing Screen Fit again.

• Because Screen Fit uses a sensor, it may not work

properly depending on the condition of the projected surface (deflections, patterns and the like) or the effects of outside light. In this case, make the adjustments manually.

When multiple projectors are set up and you need to make corrections, use the following procedure to correct one projector at a time.

1. Set the projector ID and the remote control ID.

Set a projector ID for the target projector, then set the same ID for the remote control, so that you can limit the operation to one target projector. s p.42

2. Correct the color difference.

You can carry out color correction when projecting from multiple projectors. You can adjust from black to white in five stages called levels 1 to 5, and in each of these 5 levels you can adjust the following two points.

• Correcting brightness You can correct the image brightness to make them all equal.

• Correcting color You can adjust the image color to make them match more close-

ly by using Color Correct. (G/R) and Color Correct. (B/Y).

Correction Method

After setting up the projectors, correct the brightness and tone for each projector to reduce the differences.

Procedure

Type of security

When the supplied or optional wireless LAN unit is installed and being used in Advanced Connection Mode, it is strongly recommended that you set security. Select one of the following security methods.

• WEP

Data is encrypted with a code key (WEP key). This mechanism prevents communication unless the encrypted keys for the access point and the projector match.

• WPA

This is an encryption standard that improves security which is a weak point of WEP. Although there are multiple kinds of WPA encryption methods, this projector uses TKIP and AES. WPA also includes user authentication functions. WPA authentication provides two methods: using an authentication server, or authenticating between a computer and an access point without a server. This projector supports the latter method, without a server.

• EAP

EAP is a protocol used for communication between clients and authentication severs. These are multiple protocols, such as EAP-TLS which uses electronic certification for user authentication, and LEAP and EAP-TTLS, which use user ID and password.

System Authentication

EAP-TLS Electronic certification, CA certification

EAP-TTLS User ID, Password

PEAP User ID, Password

LEAP User ID, Password

List of Functions

• For setting details, follow the directions from the network administrator of your network.

• If using EAP, you need to make settings at the projector that match the authentication server settings. Check with your network administrator for details on RADIUS settings.

• Save the electronic certificate and the CA certificate onto a USB storage device and register them to the projector with PC Free. Only one pair of electronic certificate and CA certificate can be registered to the projector. These certificates are used with EAP-TLS.s Projector Operation Guide (EB-1925W/

Appendix

This chapter provides information on maintenance procedures to ensure the best level of performance from the projector for a long time to come.

Installation Methods

The projector supports the following four different projection methods. Install according to the conditions of the installation location.

Warning

•

A special method of installation is required when suspending the projector from a ceiling (ceiling mount). If it is not installed correctly, it could fall causing an accident and injury.

•

If you use adhesives on the Ceiling mount fixing points to prevent the screws from loosening, or if you use things such as lubricants or oils on the projector, the projector case may crack causing it to fall from its ceiling mount. This could cause serious injury to anyone under the ceiling mount and could damage the projector. When installing or adjusting the Ceiling mount, do not use adhesives to prevent the screws from loosening and do not use oils or lubricants and so on.

Attention

Do not use the projector on its side. This may cause malfunctions to occur.

• Project images from in front of a screen (Front projection)

• Project images from behind a translucent screen. (Rear projection)

• Suspend the projector from the ceiling and project images from in front of a screen (Front/Ceiling projection)

• An optional Ceiling mount is required when suspending the

projector from a ceiling. s p.104

• You can change the setting as follows by pressing down the [A/ V Mute] button on the Remote Control for about five seconds.

FrontWFront/Ceiling Set Rear or Rear/Ceiling from the Configuration Menu.s p.58

• Suspend the projector from the ceiling and project images from behind a translucent screen. (Rear/Ceiling projection)

Cleaning

You should clean the projector if it becomes dirty or if the quality of projected images starts to deteriorate.

Attention

Turn off the projector's power before cleaning.

Cleaning the Projector's Surface

Clean the projector's surface by wiping it gently with a soft cloth.

If the projector is particularly dirty, moisten the cloth with water containing a small amount of neutral detergent, and then firmly wring the cloth dry before using it to wipe the projector's surface.

Attention

Do not use volatile substances such as wax, alcohol, or thinner to clean the projector's surface. The quality of the case may change or become discolored.

Cleaning the Lens

Use a commercially available cloth for cleaning glasses to gently wipe the lens.

Warning

Do not use sprays that contain flammable gas to remove dust and lint from the lens. The projector may catch fire due to the high internal temperature of the lamp.

Attention

Do not rub the lens with harsh materials or subject the lens to shocks, as it can easily become damaged.

Cleaning

Cleaning the Air filter

Clean the air filter and the Air intake vent when the following message is displayed.

"The projector is overheating. Make sure nothing is blocking the air vent, and clean or replace the air filter."

Attention

•

If dust collects on the air filter it can cause the internal temperature of the projector to rise, and this can lead to problems with operation and shorten the optical engine's service life. Clean the air filter immediately when the message is displayed.

•

Do not rinse the air filter in water. Do not use detergents or solvents.

• If a message is frequently displayed, even after cleaning, it is time to replace the air filter. Replace it with a new air filter. s p.102

• It is recommended that you clean these parts at least once every three months. Clean them more often than this if using the projector in a particularly dusty environment.

Replacing Consumables

This section explains how to replace the Remote Control batteries, the Lamp, and the air filter.

Replacing the Remote Control Batteries

If delays in the responsiveness of the Remote Control occur or if it does not operate after it has been used for some time, it probably means that the batteries are becoming flat. When this happens, replace them with new batteries. Have two AA size manganese or alkaline batteries ready. You cannot use other batteries except for the AA size manganese or alkaline.

Replacing the Lamp

Lamp replacement period

It is time to replace the Lamp when:

• The message "Replace the lamp." is displayed at the lower left of the projection screen when you start projecting.

A message is displayed.

• The Lamp indicator flashes orange.

Attention

•

The lamp replacement message is set to appear after the following time periods in order to maintain the initial brightness and quality of the projected images.

When Power Consumption is set to Normal: About 2400 hours When Power Consumption is set to ECO: About 3400 hours

•

If you continue to use the Lamp after the replacement period has passed, the possibility that the lamp may explode increases. When the Lamp replacement message appears, replace the Lamp with a new one as soon as possible, even if it is still working.

•

Do not repeatedly turn off the power and immediately back on. Turning the power on and off frequently may shorten the lamp's operating life.

•

Depending on the characteristics of the Lamp and the way it has been used, the lamp may become darker or stop working before the lamp warning message appears. You should always have a spare lamp unit ready in case it is needed.

How to replace the Lamp

The Lamp can be replaced even when the projector is suspended from a ceiling.

• The projected image gets darker or starts to deteriorate.

Warning
