 While the projector is connected to a computer over a wireless LAN, a Network Connection
window like the one shown below will be displayed on the computer screen. The computer
screen image (main screen) will be projected.
 For details about Network Connection window operations, see the separate "Network
Connection Guide".
Note
(Wireless LAN connection using Generic SSID or user SSID)
 After you perform the above operation, Network Connection will remember the passphrase
used for the last connection. Because of this, you will not need to input the passphrase again
if you re-connect the same computer to the projector (as long as the SSID has not been
changed).
 Settings can be configured to eliminate the need for login code input. For information about
how to configure settings, see "Configure Control Panel page network settings" (page 22).
