To reboot the Solar MD SS202-05 battery and reset the logger, follow these steps:

1. Turn the BMS board ON/OFF switch to the OFF position.
2. Wait briefly to allow all voltages to drop to safe levels.
3. Turn the BMS board ON/OFF switch back to the ON position.
4. If not already connected, connect the Multipurpose button to the BMS board.
5. Press and hold the Multipurpose button until the light comes on.

This process reboots the battery and resets the system.
