can u use 2 bolts in the same home w/o issues (explained below)?

Hi, yesterday I bought 2 TiVo Bolts 1tb each. I planned to use them on comcast xfinity.I am worried thinking into it now, when I power the one receiver, will it "power" on the other receiver in the other room. One Tivo is for me, the other is for my elderly parents. We each wanted to record our own programming on our "own" separate receiver, thus buying 2 TiVos. Does anyone who owns this model have a setup like I want to test it out and see if that's how it works or if I'll be ok and they won't power on each other (at the same time & won't remove the recordings from both receivers at the same time,which I don't want). I hope that made sense to you guys if anyone replies to this question.Please let me know asap.I know it's late but I'm supposed to be getting service installed today, 5-11-16. I really hope they don't power on each other at the same time and delete recordings on each one. (I know with dish network-our former setup, the receivers had the ability to change the address key for each receiver,so we never had issues with the other powering on the other once that was done but I don't think that option is on the TiVo Bolts.) Anyone, help please. Thanks.
