How to check the battery level of the DM13?
When powering on, short press the first button (power button). In the display, BAT5 means full power, BAT4 means 80~90% power, BAT3 means 60~80% power, BAT2 means 40~60% power, BAT1 means 20~40% power, and BAT0 means low power (DM13 needs to be charged).
It is recommended to use a 5V 2A adapter to power the DM13.
For long-term use, it is recommended to use an adapter with stable 5V power supply. Adapters with fast charging function are not recommended.
