Troubleshooting
This section gives recommendations for general checks and actions for problems operating
the SMX.
1. Ensure that all devices are plugged in and powered on. The SMX is receiving power if
one of the front panel power supply LEDs is lit green.
2. Check to see if one or more outputs are muted.
3. Ensure that an active input is selected for output on the SMX.
4. Ensure that the proper signal format is supplied.
5. Check the cabling and make corrections as necessary.
6. Call the Extron S3 Sales and Technical Support Hotline if necessary (see the rear cover
for the contact phone numbers in your region of the world).
