requires recharging.

refer to the LCD display.
If the battery icon is flashing, or the display is
blank, you have to recharge the case before
you can use it to charge your earpiece.

before connecting to the charging jack on
the side of the case.
While the case is recharging, the LCD battery
icon (above the case image) flashes to indicate
charge level.
