Blinking Red indicates charge is needed. If the battery is drained it will continue to blink red while charging until there is enough charge. I would let it charge completely before trying to use it this time until the battery light turns green indicating battery is fully charged. If needed, you can do a SoundLink speaker reset, following these steps:
- On the speaker, press and hold MUTE for 10 seconds; the LED will flash briefly
-Press Power to turn the SoundLink back on
If either of these answers do not help, you may need to exchange it. Good Luck and please let us know... John
