Getting started
The indicator light will flash blue. It will then turn off and the circle LED will start to turn on
clockwise, and the speaker will turn on.
Use only Samsung-approved power cable provided with the speaker.
To save energy, unplug the power cable when not in use. The power cable does not
have a power switch, so you must unplug the power cable from the electric socket
when not in use to avoid wasting power. The speaker should remain close to the
electric socket and easily accessible while charging.
Q I want to turn off the power.
A This speaker does not have a power button. Simply unplug the power cable from
the electric socket.
