That is incorrect, at least according to the information provided to me (I am a Canadian Authorized Dealer). Only one MRX-1 may be used with one iOS Setup Code. Your code is permanently tied to the MRX-1 in URC database once you set it up. You may use multiple iOS devices per iOS setup code/MRX-1 combination, just no more than one MRX-1. If the MRX-1 malfunctions and you need to replace it, you will need to contact URC to have the code unlinked to the old MRX-1, and then you'll be able to link it to a new one.
