The MC4-R's built-in infiNET EX radio firmware was upgraded with the release of Crestron
Home version 3.004.0071 and is not backwards compatible. If it is necessary to downgrade the
MC4-R control processor firmware from 3.004.0071 or later to 3.003.0035 or earlier, downgrade
the infiNET EX radio firmware prior to downgrading control processor firmware.
To downgrade the MC4-R control processor firmware, follow these steps:

NOTES:

(3.003.0035 or earlier) and then transfer it to the MC4-R's /Firmware folder.
