Preparation

Preparation for projection

1. Attach the provided AC adapter to the projector.

2. Plug the AC adapter in the wall outlet.
The POWER indicator lights red when using the
AC adapter.

Warning:

Do not look into the lens directly when the projector is
on.
Use 100-240 V AC 50/60 Hz to prevent fire or electric
shock.
Do not place any objects on the AC adapter and power
cord or do not place the projector near heat sources
to prevent damage to the power cord. If either the AC
adapter or power cord should be damaged, contact
your dealer for replacement because it may cause
fire or electric shock.
Do not modify or alter the AC adapter. If the AC adapter
is modified or altered, it may cause fire or electric
shock.

Caution:

Plug in the power cord firmly. When unplugging, hold
and pull the power plug, not the power cord.
Do not plug in or out the power cord with your hand
wet. It may cause electric shock.

Important:

Install the screen on a flat wall at 90 degrees to the floor.
Images may not be projected in a shape of a regular
rectangle or with its aspect ratio 4:3, depending on the
installation conditions of the projector and the screen.
To correct vertical keystone distortion:
On the optional remote control: press the KEYSTONE

T buttons.

S

On the control panel: adjust KEYSTONE in the
INSTALLATION menu.

In the following cases:

Press the KEYSTONE S. Press the KEYSTONE T.

EN-18

Important:

When the keystone adjustment is carried out, the adjustment value is indicated. Note that this value doesn’t mean
a projection angle.
The allowable range of the adjustment value in the keystone adjustment varies depending on the installation
conditions.
When the keystone adjustment takes effect, the resolution decreases. In addition, stripes may appear or straight
lines may bend in images with complicated patterns. They are not due to product malfunctions.
Noise may appear on the screen during the keystone adjustment because of the type of the video signal being
projected and the setting values of the keystone adjustment. In such cases, set the keystone adjustment values in
the range where the image is displayed without noise.
When the keystone adjustment is carried out, the image may not be displayed correctly because of the type of input
signal.

LAMP(Red) POWER(Red) Charge(Red) Solution
Off Off Off

Cancel blanking by pressing the BLANK button.
On rare occasion, the lamp fails to light up. In such cases, try to light the lamp
again.
Check that the cable connected to the external device isn’t broken.
When an extension cord is being used, replace it with the supplied cable and check
whether images are projected correctly.
The air inlet or outlet grille may be blocked.
t Remove the objects blocking the air inlet or outlet grille and carry out the
following.

1. Wait for the air inlet or outlet fan to stop (or wait for the LAMP indicator to go out.)

2. Unplug the power cord from the wall outlet.

3. Wait about 1 minute.

4. Plug the power cord into the wall outlet.

5. Press the POWER button.

Check that the battery or power cord connected with the projector correctly.

Connect the power cord to the projector.
Plug the power cord into a wall outlet.

Problem Cause and solution

No source found.

Turn on the power of the connected device, or check whether there is something wrong
with the connected device.
Check whether the external device outputs signals. (Check this especially when the
external device is a notebook computer.)
Check that the cable connected to the external device isn’t defective.
Check that the projector is connected to the external device using the correct
terminals.
Check that the connected device is correctly selected as the input source.
When an extension cord is being used, replace it with the supplied cable and check
whether images are projected correctly.

Images aren’t projected cor rectly.

Problem Cause and solution

Projected images are shaking.
Projected images are displaced.

Projected images are distorted.
Projected images are dark.

Projected images are blurred.

White dots are seen on projected
images.
Black dots are seen on projected
images.

Check that the cable connected to the external device isn’t intermittent.
Connect the cable’s plug with the external device’s connector firmly.
Some computers output out-of-spec signals on rare occasion Adjust the SIGNAL
menu.

Adjust the projector and the screen so that they are perpendicular to each other.

This symptom is normal for a DLP projector and is not a malfunction. (A very small
number of pixels may stay lit or out, but such sympton is not a malfunction. Pixels
of 99.99% or more are effective.)

EN-29

Problem

Rainbow blurprojected images.

Fine streak pattern appears in projected images.

Projected images appear wavy and distorted.

Tint in projected images is incorrect.

Only the motion areas in the images
supplied from the computer aren’t displayed.

Projected images are obscured.

Cause and solution

This is due to color breaking noise that occurs in a DLP system and is not a malfunction.
It occurs because of interference with the screen and isn’t a product malfunction.
Change the screen or readjust the focus of the projector.

Connect the cable’s plug with the external device’s connector firmly.
Keep the projector away from equipment generating interfering radio waves.
When the keystone adjustment is carried out, the image may not be displayed
correctly because of the type of input signal. This isn’t a product malfunction.
In this case, readjust the keystone so that the amount of keystone correction
is as small as possible.

Check that the cable connected to the external device isn’t broken.

This is caused by the computer being used. Contact the manufacturer of your
computer.

Match the output resolution of your computer with the resolution of the projector. For the
method to change the output resolution of the computer, contact the manufacturer
of your computer.
Some images and texts appear obscured during the keystone adjustment.
In such cases, use the projector without applying the keystone adjustment.

EN-30

Others

Problem

Hot air is emitted from the air outlet grilles.

The menu can’t be used.

The remote control doesn’t function easily

a product malfunction.

The microcomputers inside the projector may be wrongly operating because
of noise.

cord from the wall outlet. Wait about 1 minute, plug the power cord in, and try
again.

Check that the battery is loaded in the remote control or the battery isn’t
weak.
