different from the setting above for when the Digital Input.
For example,
With 'Audio Muting' set for ‘AV Out’ (both Audio and Video muted) and the ‘Digital

state shown in the ‘Audio Muting’ area will change from ‘AV OUT’ to ‘AUDIO OUT’
Troubleshooting
If you are experiencing problems getting the system to work properly, please use the following
troubleshooting suggestions.
•
Ensure that all connections to the device are solid. Loose connections are the number one
cause of issues.
•
Try resetting the system by unplugging BOTH the power supply and HDMI IN connectors,
waiting 5 seconds and plugging them back in.
-
The front panel LEDs cycle several times at power up; after ~15 seconds, audio and video
should be passing through the device.
•
Try restoring factory defaults using the front panel VIDEO EDID button (hold for 7 seconds) or
via RS-232 command.
•
Cycle the EDID mode with the front panel VIDEO EDID button.
•
If you are having problems with ‘muting’ the AV output, ensure you have the correct mute
settings.
-
The muting of video is normally done with a ‘BLACK’ screen (AVMUTE). If you need to have
“NO HDMI” output, you will need to use the TX MUTE setting (DIA7 or MUT7).
