It was just fine and I refilled it.
Press the button and it blinks green 5 times and won't fire.
Remove the atty, check it out on the meter even tho it was the same one that was on it.
Reads just fine.
Put it back on, press the button, 5 green blinks.
Remove the battery, replace it with another...same thing.
Remove and reinstall atty...same thing.
Different atty...same thing.
Another battery...same thing.
Left it for the night (without a battery in it).
This morning same thing BUT - now it blinks green 5 times and goes to blue and shuts off.
Over and over again and again.
