Check the ECP’s volume knob or use the projector’s remote control to ensure that the volume
isn’t at the lowest setting.

If you’re using an external audio system, ensure that your speaker or audio system is on and that
the volume is turned up.

Check that your video 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.
N O T E
You must display the source input’s video to play its audio through the connected speakers or
audio system.
l
Ensure that the correct audio output device is selected in your computer’s Sound settings.
l
If your computer's video signal is connected with an HDMI cable, ensure that your computer's
audio output is also configured to output audio via the same HDMI cable. If your computer's
video signal is connected with a VGA cable, ensure that your computer's audio output is
configured to use its analog audio cable connected between the computer and the projector.
N O T E
If you're using an HDMI video input on the projector, don’t use any DVI to HDMI adapters,
because they don’t transfer audio from the DVI source to the HDMI input on the projector.

If the previous steps don’t resolve the issue, contact your authorized SMART reseller.
Resolving network communication issues
If you don’t have network access, perform the following procedure to troubleshoot your system.
To resolve network communication issues
1.
Ensure that your network cable is properly connected to the internet connection on the
projector’s connection panel. There are two RJ45 (8P8C) ports: one is for the network and one is
for projector 2. Ensure that the network cable 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
on page 67). The network features on the projector don’t work until you complete one of
these tasks.
Ensure that the network is enabled in the projector's on-screen display menu.
