The red LED next to the REMOTE input jack blinks TWICE , not once, when powering up the TIU. I have connected the remote using a handset tether to the remote jack, and I still get OUT OF RF RANGE or TIU ERROR, NO TIU FOUND, and the READ button does nothing. I removed and re-seated the small RF transceiver board to no avail. I think my TIU is hosed. But it's strangely related to the backup operation I did last session. I was backing up the remote and it finished early (about 10 min) where I was expecting it to take 15 to 20 min, but it did say COMPLETE. I DID NOT accidentally plug the handset cord into the wrong jack, I was very aware of that from the warnings. I see three options: REPLACE the TIU with a new one, buy or exchange the TIU Board, if MTH does exchanges, or send it in for repair if they do that. I don't know which of those options are the usual approach. I will call MTH on FRiday.
