Information
Cautions when setting the projectors J
 zDo not stack the projectors.
Do not block the ventilation ports (intake and exhaust)  z
of the projector.
Avoid heating and cooling air from the air conditioning  z
system directly blow to the ventilation ports (intake and 
exhaust) of the projector.
Make sure that there is no object under the projector  z
to prevent from covering the bottom openings.

Do not place the projector in an enclosed space.  z
If you need to place the projector in an enclosed space, additional air conditioning and ventilation system 
must be equipped. When ventilation is insufficient, remaining heat may trigger the protection circuit of the 
projector.

							Precautions for Use
12 - ENGLISH
Important 
 
InformationCautions on use
In order to get the picture quality J
Draw curtains or blinds over windows and turn off any lights near the screen to prevent outside light or light  z
from indoor lamps from shining onto the screen.
Depending on where the projector is used, heated air from an exhaust port or warm or cold air from an air  z
conditioner can cause a shimmering effect on screen. 
Avoid use in locations where exhaust or streams of air from projector, other devices and air conditioners flow 
between the projector and the screen.
The lens of projector is affected by the heat from the luminous source. Because of this, the focusing stays  z
unstable right after the power is turned on. Focusing is stabled after projecting image for 30 minutes and 
longer.
Do not touch the surface of the projector lens with your bare hand. J
If the surface of the lens becomes dirty from fingerprints or anything else, this will be magnified and projected 
onto the screen.
LCD Panel J
The display unit of this projector comprises three LCD panels. Although an LCD panel is a product of high-
precision technology, some of the pixels on the projected image may be missing or constantly lit. Please note that 
this is not a malfunction. 
Displaying a still image for a longer time may result in an after-image \
on the LCD panels. If this happens, display 
the all white screen in the test pattern for an hour or more.
Optical components J
Operating the projector in an environment with high temperature or heavy exposure to dust or tobacco smoke 
will reduce the service life of the optical components, such as the LCD panel and polarizing plate, and may 
necessitate their replacement within less than one year of use. For deta\
ils, consult your dealer.
Lamp J
The luminous source of the projector is a mercury lamp with high internal pressure.
A high pressure mercury lamp has following characteristics.
The brightness of the lamp will decrease by duration of usage. z
The lamp may burst with sound or shorten life by shock or chipping. z
The life of the lamp varies greatly depending on individual specificities and usage conditions. In particular,  z
continuous use over 6 hours and frequent on/off switching of the power greatly deteriorate the lamp and affect 
the lamp life.
In rare cases, the lamp burst shortly after the projection. z
The risk of bursting increases when the lamp is used beyond its replacem\
ent cycle. Make sure to replace the  z
lamp unit consistently. (“When to replace the lamp unit” (Æ page 61))
If the lamp bursts, gas contained inside of the lamp is released in a fo\
rm of smoke. z
It is recommended to store replacement lamps for contingency. z
It is recommended to have authorized engineer or your dealer replace the lamp unit. z

Attention
Do not drop the remote control. z
Avoid contact with liquids. z
Do not attempt to modify or disassemble the remote  z
control.
Note
The remote control can be used within a distance of  z
about 7 m (22.97 ft) if pointed directly at the remote 
control signal receiver. The remote control can control at 
angles of up to ± 30 ° vertically and ± 30 ° horizontally, 
but the effective control range may be reduced.
If there are any obstacles between the remote control  z
and the remote control signal receiver, the remote control 
may not operate correctly.
You can operate the projector by reflecting the remote  z
control signal on the screen. The operating range may 
differ due to the loss of light caused by the properties of 
the screen.
When the remote control signal receiver is lit with a  z
fluorescent light or other strong light source, the projector 
may become inoperative. Set the projector as far from 
the luminous source as possible.

Using Remote control
Installing and Removing batteries
Open the cover1 ) Install batteries and close the cover2 ) 
(Insert the – side first.)
Remove the batteries in the reverse order of  z
installation. 
Setting Remote control ID numbers
When you use the system with multiple projectors, you can operate all the projectors simultaneously or each 
projector individually using single remote control, if unique ID number is assigned to each projector.
After setting the ID number of the projector, set the same ID number to the remote control.
There are 7 different ID codes (ALL, Code 1~Code 6), the initial ID number is [ALL].
 JSetting the ID number
  1) While holding down the  button, press the  button. The number of times you press the 
       button corresponds to the desired ID code number.
  2) The number of times to press the  button is as follows: 
      Code 1= Once, Code 2= Twice, Code 3= 3 times, Code 4= 4 times
      Code 5= 5 times, Code 6= 6 times
  3) The ID code is changed when the  button is released.
  4) The ID code is reset to [ALL] (default) by pressing the  button \
and  button at the same 
      time for 5 seconds or more.
Attention
If the  button is pressed 7 times or more, the ID code                                                                                            z
cannot be changed (the operation is invalid).
The status of the ID code is not stored after replacing batteries. z

Attention
For optimum viewing quality, install the projector in a location where screen exposure to outside light, light from light fixtures  z
or other light is at a minimum. Also draw the curtains, close blinds and turn off light fixtures. 
Do not use the projector installed vertically or tilted right or left. Use under such conditions could result in equipment  z
damage.
The projector must be installed so that its inclination to the horizontal plane is ±30° or less.  z
Installing the projector at an inclination that exceeds 30° may reduce product life or                                                                                                                                                z
result in malfunction.
Parts for ceiling mount (Optional)
You can install the projector on the ceiling by using the optional ceiling mount bracket (ET-PKV100H: for high 
ceiling, ET-PKV100S: for low ceiling), and the optional projector mount base ET-PKL100B.
Use only the ceiling mount brackets specified for this projector. z
Refer to the installation manual for the ceiling mount bracket when you install the bracket and the projector. z
Attention
To ensure projector performance and security, installation of the ceiling mount bracket must be carried by your  z
dealer or a qualified technician.
