About the Interactive light pen
Installing and Removing batteries
Rotate as shown in the figure. 1 ) 
Install 2 AAA/R03 or AAA/LR03 type batteries. 2 )  
*  Remove the batteries in the reverse order of installation.
How to use the pen
While pressing the tip against a hard screen, the tip of the pen and the LED for the internal infrared ray will both 
light. This is sensed by the infrared ray sensor on the front of the projector, and the location of the tip of the pen is 
detected.
1) Press the power button to turn the power on.
2)   Place the tip of the pen anywhere on the screen.
3)  By pressing the tip against a hard screen, you can drag. In pen mode, you can draw lines.
Attention
Since there is a touch sensor inside the tip of the pen, pushing or bending the tip will consume battery power . In order to  z
prevent unnecessary battery consumption when not in use, press the power button to turn the power off. (Press the tip of 
the pen to confirm that the LED does not light.)

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), the optional projector mount bracket ET-PKL300B.
Use only the ceiling mount brackets specified for this projector. z
Refer to the installation instructions for the ceiling mount bracket whe\
n you install the bracket or hanger and  z
the projector.
Attention
To ensure projector performance and security, installation of the ceiling mount bracket must be carried by your deal\
er or a  z
qualified technician.

Screen size and throw distance
Place the projector referring to the diagram on the right and the figures of throwing distance. You can adjust the 
display size. 
Attention
Before installing, please read “Precautions for Use”. ( zÆ pages 11 to 15)
 
Do not use the projector and the high-powered laser equipment in the same room. Hitting of a laser beam on to the lens  z
can damage the DLP chips.

Calculation formulas for projection distance Q
Any other projection distance can be obtained according to the screen dimensions (m) using the following 
calculations. The calculation result is with the "m" unit. (The calculated distance below may contain a certain 
error.) If the screen dimensions are written as "SD",
For 4*3 aspect ratioFor 16:9 aspect ratioFor 16*10 aspect ratio
Screen height (SH)= SD × 0.6= SD × 0.490= SD × 0.530
Screen width (SW)= SD × 0.8= SD × 0.872= SD × 0.848
Projection distance (L)= 0.500 × SD= 0.454 × SD= 0.442 × SD
Note
The throw ratio is 0.52:1 when the projection size is 100 inch. z

Getting Started
Before connecting to the projector
Read carefully the instruction manual for the device to be connected. z
Turn off the power switch of the devices before connecting cables. z
If any connection cable is not supplied with the device, or if no option\
al cable is available for connection of the  z
device, prepare a necessary system connection cable to suit the device.
Video signals containing too much jitter may cause the images on the scre\
en to randomly wobble or wafture.   z
In this case, a time base corrector (TBC) must be connected.
The projector accepts the following signals: VIDEO, analogue-RGB (with TTL sync. Level) and digital signal. z
Some computer models are not compatible with the projector. z
When using long cables to connect with each of equipment to the projecto\
r, there is a possibility that the image  z
will not be output correctly unless a compensator is used.
For details on what video signals the projector supports, see “List of compatible signals”. ( zÆpages 67-68)
Attention
When connecting with a video deck, be sure to use the one with a built-in time base corrector (TBC) or use a  TBC between  z
the projector and the video deck.
If nonstandard burst signals are connected, the image may be distorted. If this is the case, connect a TBC between the  z
projector and the video deck.
Note
Use an HDMI cable that conforms to HDMI standards such as an HDMI High Speed cable. If a cable that does not meet  z
HDMI standards is used, video may be interrupted or may not be displayed.  
When connecting the 1080p signal using HDMI, use a cable compliant with 1080p signal.
This projector does not support the VIERA Link (HDMI). z
