DHCP. Otherwise, turn off DHCP and enter the following 
information manually: 
■IP address: Type in the IP address you want to assign to the 
projector. It must be formatted like other addresses on the 
network; usually the first three numbers (XXX.XXX.XXX)

on how your network is set up.
■Gateway address: Enter the IP address that was assigned to 
the access point when it was set up.

							Presenting Through a Wireless Network43
If you don’t see any projectors listed, click Option, then click 
Switch LAN. Verify that the correct (wireless) network device is 
selected. Sometimes another network device, such as an Ethernet 
card, may be selected instead. If you don’t see your wireless device 
listed, but you’re sure you’ve enabled it as described in 
“Configuring the Connection” on page 29, you may need to 
restart your computer. 
2. Once the name of your projector appears, select it and click 
Connect. If more than one projector is listed, you can select 
additional ones to connect to them at the same time. If the 
selected projector is already being used by another person, you can 
still connect to it; doing so automatically disconnects the other 
user (see page 45).
3. If you set up the projector to prompt you for a keyword before 
connecting, you see this screen:
Type in the four-digit number displayed by the projector and 
click 
OK.
