After you
select the wireless network settings for your projector, you can
display a QR code on the screen and use it to connect a mobile
device using the Epson iProjection app.
To correctly read the QR code,
make sure you face the screen squarely and are close enough so that
the projected code fits into the guide of the mobile device's QR
code reader. If you are too far from the screen, the code may not
be read.
