# Power Management

Before enabling the Barcode reader, application will check the battery charge level. If the battery level is less than 10 percent and the device is not charging, barcode library will send error code '8' indicating that the barcode module cannot be opened due to low battery voltage.

Also when the scanning session is on i.e. after start scan command when the barcode module sends the asynchronous barcode data or button status, if the battery level falls below 10 percent and device is not in charging mode, the barcode module will be closed.
