Using the remote control
Inserting and Removing batteries
Fig. 1Fig. 2
1) Open the cover. (Fig. 1)
2) Insert batteries and close the cover (Insert the "m" side first.). (Fig. 2)
 fWhen removing the batteries, perform the steps in reverse order.
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 assigne\
d 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].
How to set
1) The ID numbers of the projector are set by pressing the  button o\
ne time to six times 
while holding down the  button. 
 fThe number of times you press the  button corresponds to the desi\
red ID code number. 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.
 fThe ID code is changed when the  button is released.
Attention
 fThe ID number set on the remote control will be stored unless it is set \
again. However, it will be returned to [All] if the 
batteries are run down or removed for a certain period of time.
Note
 fSet the ID number of the projector from the [Expand] menu → [Remote control]. (x page 68)
 fThe ID code is reset to [All] (default) by pressing the  button and  button at the same time for 5 seconds 
or more.
 fIf the  button is pressed 7 times or more, the operation is inval\
id, the ID code cannot be changed.

Installing and Removing batteries
(i)
(ii)
1) Rotate the cap of the pen in the direction as shown in Figure 1. 
2) Install batteries in the direction as shown in Figure 2 and rotate the c\
ap of the pen in the reverse 
direction to close. 
 f 
Remove the batteries in the reverse order of installation. 
How to use the pen
While pressing the tip against a hard screen, the LED for infrared ray i\
n the tip of the pen will 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.
 fClick the power button to turn on the power and make sure that the inside LED is lit up by pressing the pen tip.
 fPlace the tip of the pen anywhere on the screen and select the toolbar i\
con on the screen.
 fBy pressing the tip against the screen and drag, you can draw on the scr\
een. 
Attention
 fSince there is a touch sensor inside the tip of the pen, pushing the tip\
 will consume battery power. In order to prevent 
unnecessary battery consumption when not in use, press the power button to turn the power of
f. (Press the tip of the pen to 
confirm that the LED does not light.)

Projection distance formulas 
To use a screen size not listed in this manual, check the screen size SD (m) and use the respective formula to calculate 
projection distance.
The unit of all the formulae is m. (Values obtained by the following calculation formulae contain a slight error.)
If you want to calculate the projection distance with projected image size SD (unit: inch) by substituting, please assign 0.0254 
times to the SD value.
4:3 aspect ratio16:9 aspect ratio16:10 aspect ratio
Screen height (SH)= 0.6 × SD= 0.490 × SD= 0.530 × SD
Screen width (SW)= 0.8 × SD= 0.872 × SD= 0.848 × SD
Projection distance (L)= 0.4625 × SD - 0.0339= 0.4188 × SD - 0.0339= 0.4085 × SD - 0.0339

down. Release your finger to lock the adjustable feet.
For slight adjustment, rotate the adjustable feet. 
Rotate the adjustable feet to extend it as shown in the figure, and rotate it in the opposite direction to contract it.
Attention
 fHeated air comes out of the air exhaust port while the lamp is lit. Do not touch the air exhaust port directly when you adjust 
the adjustable feet.

Connecting
Before connecting
 fBefore connecting, carefully read the operating instructions for the external device to be connected.
 fTurn off the power switch of the devices before connecting cables.
 fTake note of the following points before connecting the cables. Failure to do so may result in malfunctions.
-  When connecting a cable to a device connected to the projector or the pr\
ojector itself, touch any nearby metallic objects to 
eliminate static electricity from your body before performing work.
-  Do not use unnecessarily long cables to connect to a device connected to\
 the projector or to the projector body. The longer 
the cable, the more it is susceptible to noise. Since using a cable whil\
e it is wound makes it act like an antenna, it is more 
susceptible to noise.
-  When connecting cables, connect GND first, then insert the connecting terminal of the connecting device in a straight 
manner.
 fIf any connection cable is not supplied with the device, or if no option\
al cable is available for connection of the device, 
prepare a necessary system connection cable to suit the device.
 fVideo signals containing too much jitter may cause the images on the scre\
en to randomly wobble or wafture. In this case, a 
time base corrector (TBC) must be connected.
 fThe projector accepts Video signals, S-video signals and YCBCR/YPBPR signals and analog RGB signals (synchronous 
signals are TTL level), and digital signal.
 fSome computer models are not compatible with the projector.
 fWhen using long cables to connect with each of equipment to the projecto\
r, there is a possibility that the image will not be 
output correctly unless a compensator is used.
 fFor details on what video signals the projector supports, see “List of compatible signals”. (x pages 96 - 97)

Attention
 fAlways use one of the following when connecting a VCR. 
- A VCR with built-in time base corrector (TBC). 
- A time base corrector (TBC) between the projector and the VCR.
 fIf nonstandard burst signals are connected, the image may be distorted. \
In such case, connect the time base corrector 
(TBC) between the projector and the external devices.
Note
 fFor an HDMI cable, use an HDMI High Speed cable that conforms to HDMI standards. If a cable that does not conform to 
HDMI standards is used, images may be interrupted or may not be displaye\
d.
 fThis projector does not support the VIERA link (HDMI).
 fWhen the  terminal is connected with cable, the sound will not be output from the built-in speaker.
 fWhen input S-video signal, the optional D-SUB - S Video Conversion cable (Model No. ET-ADSV) is required.
