Making a WPS (Wi-Fi Protected Setup)

settings for the connection between the projector and the access point 
from the projector’s Configuration menu using one of these methods:
■Push Button Method
Press both the 
Enter button on the projector and the button on 
the access point to make the SSID and security settings. This 
method is recommended when the projector and access point are 
close together.
■PIN Code Method
With the PIN code method, you enter an 8-digit code from the 
computer to enable the SSID and security settings. The 
connection between the computer and the access point must have 
already been established. (For connection instructions, refer to the 
manual provided with the access point.) This method lets you 
make the settings without having to press any buttons on the 
projector, and is recommended when the projector is mounted on 
the ceiling.
