2. Press the Mute button on the projector’s remote control. If Audio Mute is on, turn it off.

3. Check the ECP’s volume knob or use the projector’s remote control to ensure that the volume

isn’t at the lowest setting.

4. Ensure that the speaker or audio system is on and that the volume is turned up.

5. Check that the 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.

NOTE

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

or audio system.

6. If the previous steps don’t resolve the issue, contact your authorized SMART reseller.

Resolving ECP issues

If the ECP isn’t receiving power, complete the following tasks:

Confirm that the ECP cable harness’s 11-pin connector is properly connected to the ECP.

Confirm that the ECP cable harness’s 7-pin min-DIN connector is properly connected to the

ECP connector on the projector.

Resolving network communication issues

If you don’t have network access, perform the following procedure to troubleshoot the system.

To resolve network communication issues

1. Ensure that the network cable is properly connected to the RJ45 connection on the

projector’s connection panel.

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

programming commands on page 69) or enable the Network and VGA Out setting (see
Adjusting projector settings on page 14). The network features on the projector don’t work
until you complete one of these tasks.

3. Press the Menu button, and then select the Network Settings menu to check the IP address.

See

Adjusting projector settings on page 14 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.
