I bought Berry R12 few days before. After 1 day of using my lighter became self test (all blue-green-red LEDs on top, then indicate the voltage by blinking of blue and green led) and stopped. If I push button it may 2 different states: 1 greed LED appeared and pushing the button only took the blinking of green LED or self test became again).
It's no information about this state in manual. May be somebody knows about this problem. I planned to use Betty on night competitions a few days later, but Luoine staff on vacation now.
With best regards, Sergey
