Precautions for Use
Cautions when transporting
When transporting the projector, hold it securely by its bottom and avoid excessive vibration and impac\
ts.  z
Doing so may damage the internal parts and result in malfunctions.
Do not transport the projector with the adjustable feet extended. Doing \
so may damage the adjustable feet. z
Cautions when installing
Do not set up the projector outdoors. J
The projector is designed for indoor use only. 
Do not use under the following conditions. J
Places where vibration and impacts occur such as in a car or vehicle: Do\
ing so may damage the internal  z
parts and result in malfunctions.
Near the exhaust of an air conditioner: Depending on the conditions of use, the screen may fluctuate in rare  z
cases due to the hot air from the air exhaust port or the heated or cool\
ed air. Make sure that the exhaust 
from the projector or other equipment, or the air from the air conditioner does not blow toward the front of 
the projector.
Near lights (studio lamps, etc.) and other locations of great temperature fluctuation (“Operating  z
environment” (Æ page 58)): Doing so may shorten the life of the lamp or result in deformation of the outer 
case and malfunctions.
Near high-voltage power lines or near motors: Doing so may interfere wit\
h the operation of the projector. z
Place where there is high-power laser equipment: Directing a laser beam onto the lens surface causes  z
damage to the DLP chips.
Be sure to ask a specialized technician when installing the product to a  J
ceiling.
This requires an optional ceiling mount bracket. 
Model No.:  ET-PKV100H (for high ceilings), ET-PKV100S (for low ceilings),  
ET- PKL300B (Projector Mount Bracket)
Lens focus J
The high clarity projection lens is thermally affected by the light from the light source, making the focus 
unstable in the period just after switching on the power. Wait at least 30 minutes with the image projected 
before adjusting the lens focus.
When using the projector at elevations below approx. 1 000 m (3 300 ft),  J
make sure [High altitude] is set to [Off].
Failure to do so may shorten the life of the internal parts and result in malfunctions.
When using the projector at elevations approx. 1 000 m (3 300 ft) and   J
approx. 3 000 m (10 000 ft), make sure [High altitude] is set to [On].
Failure to do so may shorten the life of the internal parts and result in malfunctions.
Do not install the projector at elevations approx. 3 000 m (10 000 ft) or  J
higher above sea level.
Failure to do so may shorten the life of the internal parts and result in malfunctions.
Confirm and set the using environment temperature [“Operating  J
environment” (Æ page 58)].

Information
Do not tilt the projector or place it on its side. J
Do not tilt the projector body more than approximately ±20 ° vertically or ±20 ° horizontally. Over-tilting may 
result in shortening the life of the components.
Within 20 °Within 20 °
Within 20 ° Within 20 °
Cautions when setting the projectors J
Do not stack the projectors. z
Do not block the ventilation ports (intake and exhaust) of the projector
. z
Avoid heating and cooling air from the air conditioning system directly blow to the ventilation ports (intake  z
and exhaust) of the projector.
Over 50 cm (1.5')Over 1 m (3.0')
Over 50 cm (1.5')
Over 50 cm (1.5')
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.
Security
Take safety measures against following incidents.
Personal information being leaked via this product. z
Unauthorized operation of this product by a malicious third party . z
Interfering or stopping of this product by a malicious third party. z
Security instruction

							Precautions for Use
14 - 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 por\
t 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 focusi\
ng may  z
not be stable 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 projection lens with your bare hand. J
If the surface of the projection lens becomes dirty from fingerprints or anything else, this will be magnified and 
projected onto the screen.
DLP chips J
The DLP chips are precision-made. Note that in rare cases, pixels of high preci\
sion could be missing or  z
always lit, but this is not a malfunction.
Directing a high power laser beam onto the projection window surface can\
 damage the DLP chips. z
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 and may necessita\
te their replacement within less than 
one year of use. For details, consult your dealer.
Lamp J
The luminous source of the projector is a mercury lamp with high interna\
l 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 22 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  z
the lamp unit consistently. (Æ page 46)
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
About connections to computer or peripheral device J
To assure continued compliance, follow the attached installation instructions, which include using the provided 
power cord and shielded interface cables when connecting to computer or \
peripheral device.

Attention
When discarding a lithium coin battery, be sure both sides (+/-) are covered with adhesive insulating tape, such as and the  z

al government.
Setting Remote control ID numbers
When you use the system with multiple projectors, you can operate all th\
e projectors simultaneously or each 
projector individually using single remote control, if unique ID number is assigned to each projector .
After setting the remote control ID of the projector, set the same remote control ID to the remote control.
There are 7 different remote control IDs: [All], [ID1]~[ID6], the initial remote control ID is [All].
Setting the remote control ID J
  1)    While holding down the  key, press the  key. The number of times you press the 
 key corresponds to the desired remote control ID.
        The number of times to press the  key is as follows: 
        ID1 = Once, ID2 = Twice, ID3 = 3 times, ID4 = 4 times, ID5 = 5 times, ID6 = 6 times.
   2)  The remote control ID is changed when the  button is released.
 JResetting the remote control ID
       The remote control ID is reset to [All] (default) by pressing the  key and  key at the 
same time for 10 seconds or more.
Note
When operating the projector under [All] code, you can operate several p\
rojectors at the same time. z
If the  button is pressed 7 times or more, the remote control ID cannot be changed (the operation is invalid). z
For setting the remote control ID codes, see [Remote ID] in the [Setting] menu. ( zÆ page 40)
If the battery is not in use for a long period of time and is removed fr\
om the remote control, the remote control ID will be  z
reset.
