months to maintain its performance.
If the speaker is not used for a long time, it may take longer to charge the built-in battery.
The rechargeable built-in battery has a life span. As time passes and the number of times that the built-in battery is
used increases, the capacity of the rechargeable built-in battery slowly decreases. When the amount of time that the
built-in battery can be used seems significantly shorter, despite having been fully charged, contact your nearest Sony
dealer.
When the amount of time that the built-in battery can be used seems significantly shorter, it could mean that the
