Installation
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-D7700U)
Minimal distance:  L=0.1123 x Screen diagonal (inch) – 0.1158
Maximal distance: L=0.1786 x Screen diagonal (inch) – 0.1013

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.
Slot cover
Remove 2 screws.
Input module Slot
Tighten the two screws.
Remove the slot cover.
Insert the input module.
Fix the input module.
Register the input signal.
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 44–47.)
