I talked to RTI tech support today and they said that they know about the power supply problem and would send me another one to resolve the loud whining problem.

Regarding the backlight the guy said it was a bad transformer in the remote and I'd have to return the remote to them to get it fixed and it's only 2 days old. I guess RTI doesn't know how to test the remotes yet to know if they are good or not prior to shipping.

It would be nice if they would offer or even agree to cross-ship a new remote for a DOA remote but no such luck. Customer service is definitely not RTI's strong suit. I'll see what my dealer says.
