To resolve network communication issues
1. Ensure that your network cable is properly connected to the RJ45 connection on the projector’s
connection panel.
2. To activate the LAN, use the “network=on” RS-232 command (see Projector programming
commands on page 64) or the “Network” projector menu option (see Network menu on page
20). The network function on the projector doesn’t work until you send one of these commands.
3. Press the Menu button, and then select the Network Settings menu to check the IP address.
See Network menu on page 20 for a description of the IP address field. Enter this IP address
into your browser or SNMP agent.
4. If you still don’t have network access, contact your network administrator. If your administrator
is unable to resolve the issue, contact your authorized SMART reseller
( smarttech.com/where ).

its audio output is on and that its volume isn’t set to the lowest position.
