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.
