During the process, the
LEARN
button will flash blue as the EDID data is copied into memory.
If the EDID was successfully learned, then the
LEARN
button will turn off. If an error was encountered during the
operation, then the
LEARN
button will flash red.
If an error is encountered, disconnect the power from the AT-ETU-SYNC, power-cycle the sink device, then
repeat steps 4 through 6. If after several attempts, the error is encountered, then this may indicate that the sink
device has a bad or corrupt EDID.

Reconnect the source (or other intermediate device) to the
HDMI IN
port on the AT-ETU-SYNC. The source will
read the EDID data stored in EDID mode 0 and use this information to send the proper audio and video formats
to the sink device.

NOTE:
EDID data will remain in EDID mode 0, even after power is disconnected. To learn a new EDID
and overwrite the existing EDID data in mode 0, repeat steps 1 through 6.
