I just tested 8+ remote controls in my house to see if it would set off my RD's laser alert. I found that the comcast cable remote control for both digital and analog cable will set off my XTR-690se for laser LSID 340 everytime, but it will not set off my Beltronics V985 or Whistler 1790se. I will have to wait until this weekend to go test all of my other RDs with it.
It's fun to shoot my XTR with my TV remote. I think my neighbors think I'm crazy though cause I was outside of the car 10 feet away pointing my remote control at it frantically pushing buttons to try to set the thing off. I kept getting funny looks from people walking by. Oh well.
