Не могу разобраться как работает данный датчик! Мучился с переводом инструкции на китайском... перевёл. Написано что-то про то, что надо вставить батарейку.. А куда?! Попробовал в разных режимах, на тот случай, что он уже готов к работе, ни на дым, ни на огонь, ни на лазерный лучик НЕ РЕАГИРУЕТ. :-((( Если кто-нибудь уже брал такую штуку, расскажите КАК оживить!
