NOTE: A. It takes up to one and a half hours to fully charge the left/right earbuds and charging case. B. To maintain the best performance of the battery, we recommend that the battery in both the earbuds and charging case are charged regularly. Do not deplete the battery of the earbuds and charging case before charging. C. To check the battery level of the charging case: Open the top cover and check the number of LEDs that are solid white. If the most left LED indicator is white, the battery can fully charge the earbuds for one cycle. If the left and middle LED indicators are white, the battery can fully charge the earbuds for two cycles. If all three LED indicators are white, the battery can fully charge the earbuds for three cycles It is strongly recommended that you charge the charging case immediately when the most left LED indicator turns orange. Please note, low battery of the charging case might cause abnormal functionality such as auto on and auto off. Battery Low Alarm and Battery Status When the battery level of the earbuds are low, you will hear the voice prompt "Battery Low" in your BE Free6 every 4 minutes. The estimated battery reserve remaining time is less than 15 minutes. Users with iOS devices and some Android models will be able to view the earbuds' battery status on their device's display. 6
