Checking the remaining battery charge | SoundTouch® Portable series II Wi-Fi® music system
To check the battery level:
On the top of your product, press and hold the Power button for 2 seconds: A battery icon appears on the system display. The amount of the icon that is filled in shows the remaining battery charge. If the product is connected to power and charging, a bolt icon appears to the left of the battery icon.

Note: If your product is disconnected from power and unused for eight days (or one day with a battery level less than 10%), it enters battery protection mode. To exit this mode, connect your product to power. Avoid storing your product for extended periods with a low charge level.
