Checking the Battery Status
If earbuds are mounted in the charging case, the earbuds' battery status is
displayed. Otherwise, the charging case's battery status is displayed.
If the earbuds are mounted in the charging case while plugged in, the
UVnano process will commence for 5 minutes. Once this process is
complete, the charging case's battery status will be displayed.
NOTE: When the charging case lid is closed, charging case battery
status is displayed. If the charging case has no remaining charge, there
will be no display and it cannot function. We recommend you keep the
charging case charged at all times as the earbuds are not able to be
turned on and turned off independently.
