XR16 Blue Blinking
I am helping out my disabled neighbor who's XR16 remote has a fast blue blink along with the keypad blinking. This often happens right after putting the batteries in, though sometimes it comes up normally when inserted (lights turn on, then fade out until a button is pressed) but then after a minute or so will return to this fast blue blink. Here is a video of the error condition:
I have also tried the remote reset procedure to no avail.
