output plug on the projector’s connection panel.
2. Press the Mute button on the projector’s remote control, and if Audio Mute is on, turn it off.
3. Use the projector’s remote control to ensure that the volume isn’t at the lowest setting.
4. Ensure that your speaker or audio system is on and that the volume is turned up.
5. Check that your source input, such as your computer or video device, isn’t malfunctioning.
Ensure that its audio output is on and that the volume isn’t set to the lowest position.

You must display the source input’s video to play its audio through the connected speakers
or audio system.

Resolving network communication issues
If you don’t have network access, perform the following procedure to troubleshoot your system.
To resolve network communication issues

projector’s connection panel. There are two RJ45 ports: one is for the network and one is for
projector 2. Ensure that the network cable is connected to the correct one.
2. Ensure that the LAN warning light on the projector is green. To activate the projector’s
network features, use the “vgaoutnetenable=on” RS-232 command (see

Adjusting projector settings
on page12). The network features on the projector don’t work
until you complete one of these tasks.

on page12 for a description of the IP address field. Enter this
IP address into your browser or SNMP agent.

is unable to resolve the issue, contact your authorized SMART reseller.
