Projection distance formulas 
Any other projection distance can be obtained according to the screen dimensions (m) by using the following calculations.
The calculated distance may contain a certain 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.
For PT-VW355N
For 4:3 aspect ratio For 16:9 aspect ratio For 16:10 aspect ratio
Screen height (SH) = 0.6 × SD(m)  = 0.490 × SD(m)= 0.530 × SD(m)
Screen width (SW) = 0.8 × SD(m) = 0.872 × SD(m)= 0.848 × SD(m)
Minimum distance (LW) = 1.1363 × SD(m) - 0.0290  = 1.0316 × SD(m) - 0.0290= 1.0037 × SD(m) - 0.0290
Maximum distance (LT) = 1.8422 × SD(m) - 0.0292  = 1.6725 × SD(m) - 0.0292= 1.6273 × SD(m) - 0.0292
For PT-VX425N
For 4:3 aspect ratio For 16:9 aspect ratio
Screen height (SH) = 0.6 × SD(m)  = 0.490 × SD(m)
Screen width (SW) = 0.8 × SD(m) = 0.872 × SD(m)
Minimum distance (LW) = 0.9461 × SD(m) - 0.0295 = 1.0307 × SD(m) - 0.0295
Maximum distance (LT) = 1.5324 × SD(m) - 0.0272 = 1.6696 × SD(m) - 0.0272

							Adjusting adjustable feet
Lift the front of the projector and press the feet lock latches on both \
side of the projector.
Release the feet lock latches to lock the adjustable feet and rotate the\
 adjustable feet to a proper height and tilt.

direction.
Feet lock latches
Adjustable range
Adjustable feet : 43 mm (1-11/16")
Attention
 
f Heated 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.
 
f If keystone distortion occurs on the projected image, perform [KEYST ONE] from the [POSITION] menu. (x page 65)
Note
 
f Screw up the adjustable feet, and an audible click will be heard as the \
limit.

							Connecting
Before connecting
 
f Before connecting, carefully read the operating instructions for the external device to be connected.
 
f Turn off the power switch of the devices before connecting cables.
 
f Take 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 projector 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.
 
f If 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.
 
f Video 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.
 
f The projector accepts VIDEO signals, S-VIDEO signals, YC
BCR/YPBPR signals and analog RGB signals (synchronous 
signals are TTL level), and digital signal.
 
f Some computer models or graphics cards are not compatible with the proje\
ctor.
 
f When using long cables to connect with each of equipment to the projector , there is a possibility that the image will not be 
output correctly unless a compensator is used.
 
f For details on what video signals the projector supports, see “List of compatible signals”. ( x page 141)

Attention
 
f Always 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.
 
f If 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
 
f For 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.
 
f This projector does not support the Viera link (HDMI).

							Attention
 
f When connecting the projector to a computer or an external device, use the power cord supplied with each device and 
commercially available shielded cables.
Note
 
f If you operate the projector using the computer with the resume feature (last memory), you may have to reset the resume 
feature to operate the projector.
 
f You can project the image and video via wired LAN, wireless LAN or the  terminal to the projector. For 
detailed information, refer to “Connecting with Wired LAN” ( x page 97), “Connecting with Wireless LAN” (x page 98) or 
the operating Instructions of “Wireless Manager ME6.3” in the supplied CD-ROM.
