Calculation formulas for projection distance by lens types (for PT-D7600U)
16:9
If the projector is used with a screen size not listed in this manual, check the diagonal dimension (inch) of your
screen and calculate the projection distance using the following formulas.
Calculation formulas for projection distance by lens types (for PT-D7500U)
Minimal distance:  L=0.1491 x Screen diagonal (inch) – 0.1145
Maximal distance: L=0.2418 x Screen diagonal (inch) – 0.1022

Connection
Before connection, read carefully the instruction
manual for the device to be connected.
Turning off the power switch of the devices
before connecting cables.
If any connection cable is not supplied with the
device, or if no optional cable is available for
connection of the device, prepare a necessary
system connection cable to suit the device.
Video signals containing too much jitter may
cause the images on the screen to randomly
wobble or wafture.  In this case, a time base
corrector...

Procedure of installation
Disconnect the power before installing the input module.
Remove the slot cover.

Insert the input module.
Input moduleSlot
Fix the input module.
Register the input signal.

Tighten the two screws.
This projector needs to register the type 
of input signal after the installation of 
the input module.
(For details on the registration of the 
input signals, refer to pages 43 and 46.)

When installing the projector, it is necessary to connect signals to the input module in accordance with the
connecting equipment.
Refer to the following diagram to establish proper signal connection. 
• When switching multiple signals of the
same type and connecting to the same
input module (for example, when using
a signal chosen from multiple high-
vision signals), use a signal selector for
this purpose and connect it with the
projector through RS-232C. Those
signals can be used individually...
