VAVA Baby Thermometer - blinking blue LED in the wand

Hi,

I have been using the baby thermometer for over 6 months now and all of a sudden there is a blinking blue LED from the wand.
I have tried to read the manual, but I cannot find any description about the blinking blue LED.
What does blinking blue LED from the wand mean? How do I clear the blinking blue LED from the wand?

Thanks!
