Note
Charging time varies depending on built-in battery usage conditions.
Charge the speaker system in an ambient temperature between 5 °C and 35 °C (41 °F and 95°F). Be aware that the room
temperature may fall to 5 °C (41 °F) or lower depending on the season, for example, especially in wintertime.
The speaker system 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 system in a car parked in the sun.
The speaker system’s built-in battery is capable of charging itself even while the speaker system is turned on. However, it may
take a long time before charging completes depending on the usage of the speaker system. It is recommended that you turn off
the speaker system before battery 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 system stop. To resolve these issues, disconnect the USB cable, and then 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.
