I had my premiere working with the RF remote dongle and the RF remote from a mini. Then I sent my premiere for a HD swap and used the mini in its place for a week. Pairing that remote back to the mini was straightforward, but now that the Premiere's back in service I can't get that remote to associate back with to the dongle. It works in IR mode and I can TiVo-D to put it in RF mode (LED color changes, at least) but the Premiere stops responding. Tried the factory reset on the remote, but I feel like the issue must be on the other end. I can't find any docs for the dongle and everything that comes up as far as putting the TiVo in pairing mode refers to the Bolt/Roamio. Does simply plugging in the USB receiver put it in pairing mode or is there something else required? Is there any status readout in the TiVo screens that indicates the presence or state of the RF adapter on a Premiere?
