What does the light colour of the digital lock tell me?

The digital lock has a handy light. Below is an overview of what the colour of the light tells you:

1. Green: correct operation mode, mode setting 
2. Red: wrong operation 
3. Blue: low battery 
4. Red, green and blue light blinking: charging 
5. Green on: the battery is fully charged
