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 rechargeable built-in battery has expired.

Ambient temperature exceeds the range of 5 °C - 35 °C (41 °F - 95 °F). There is a problem with the built-in battery. When charging to the built-in battery continues for a long time. Note Charging time varies depending on built-in battery usage conditions. Charge the speaker in an ambient temperature between 5 °C and 35 °C (41 °F and 95 °F). The speaker becomes warm during charging. This is not a malfunction. Avoid exposure to rapid temperature change, direct sunlight, mist, sand, dust, or mechanical shock. Also, never leave the speaker in a car parked in the sun. A speaker that is in use can be charged if it is connected to an AC outlet via a USB AC adaptor (commercially available), or connected to a booted computer. In this case, it may take longer to charge the built-in battery depending on the conditions of use. Therefore, it is recommended to turn off the speaker when charging. In an extremely cold or hot environment, charging stops for safety. If charging takes a long time, it also makes charging of the speaker stop. To resolve these issues, disconnect the micro-USB cable from the speaker and connect it again within an operating temperature between 5 °C and 35 °C (41 °F and 95 °F). At high temperature, the charging may stop or the volume may reduce to protect the battery. Even if you do not intend to use the unit for a long time, charge the battery to its full capacity once every 6 months to maintain its performance. Charging from a USB hub is only guaranteed when you use a self-powered USB hub that carries an authorized logo. 77
