Panasonic LCD Projector Pt Tw342 Operating Instructions

							ENGLISH - 21
Attention
 
f Do not block the ventilation ports (intake and exhaust) of the projector .
WARNING
Keep your hands and other objects away from the air exhaust port.
 
f Keep your hand and face away.
 
f Do not insert your finger.
 
f Keep heat-sensitive articles away.
Heated air from the air exhaust port can cause burns, injury, or deformations.
Note
 
f The remote control can be used within a distance of about 5 m (16'4-13/16") 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.
 
f If there are any obstacles between the remote control and the remote con\
trol signal receiver, the remote control may not 
operate correctly.
 
f You can operate the projector by reflecting the remote control signal on the screen. The operating range may differ due to 
the loss of light caused by the properties of the screen.
 
f When the remote control signal receiver is lit with a fluorescent light or other strong light source, the projector may become 
inoperative. Set the projector as far from the luminous source as possib\
le.

2)  Insert batteries and close the cover (Insert the "m" side first.).  (Fig. 2)
 
f When removing the batteries, perform the steps in reverse order.
When using the multiple projectors
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 assigne\
d to each projector.
When you want to set the ID number, at first you need to set the ID number of the projector, and then set the ID number on the 
remote control. 
The factory default ID number of the unit (the projector and the remote control) is set to [ALL], you can control with this setting. 
If necessary, please set the ID number to the remote control and the projector.
About how to set the ID number of the remote control, please refer to “Setting the remote control ID numbers”. ( x page 42)
Note
 
f Set the ID number of the projector from the [Expand] menu → [Remote control]. (x page 69)

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.
For PT-TW342
4:3 aspect ratio 16:9 aspect ratio 16:10 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
For PT-TX402 and PT-TX312
4:3 aspect ratio 16:9 aspect ratio
Screen height (SH) = 0.6 × SD = 0.490 × SD
Screen width (SW) = 0.8 × SD = 0.872 × SD
Projection distance (L) = 0.3846 × SD - 0.0339 = 0.4188 × SD - 0.0339

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 and 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 105)
