Notes:
The battery lifetime will last longer if you follow up below
simple guidelines for charging and storing.
a. For charging first time, charge it at least 10 hours. And the
battery will provide the best performance after fully
charge and discharge 3 times. It is better to charge the unit
after discharge completely, otherwise there may impact
the battery's lifetime.
b. Recharge and store the unit within the temperature range
of 5°C~35°C (40°F~95°F).
c. Do not charge the battery for a period longer than 24
hours. Excessive charging may shorten the battery's life.
d. During charging, you can play the music at the same time.
e. Please don't use it under the high humidity and
temperature environment for long time.
f. Please turn off the speaker if long time not to use.
Important:
We do not recommend taking out the battery and playing
music base on USB power connection directly. Because that
will pop up some unexpected noise.
Due to prolong charging and discharging, the unit battery life
will be affected and playback will also be shorten. We cannot
guarantee the same playback consistently throughout and this
is not include in our warranty and service.
