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 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
Projector
programming commands
on page63) or enable the Network and VGA Out setting (see
Adjusting projector settings
on page12). 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 page12 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.
Accessing the service menu
CAUTION
l To prevent tampering or unintentional changes, only system administrators should access
the service menu. Do not share the service menu access code with casual users of the
interactive whiteboard system.
l Do not adjust any settings in the service menu other than those listed in this guide. Changing
other settings can damage or affect the operation of the projector and may invalidate the
warranty.
