Charging the system

  1. Open the jack cover of the system.

  1. Connect the supplied micro-USB cable to the system, and then connect the other end to a computer.

Make sure that you connect the plug of the micro-USB cable in the direction as shown in the illustration below.
Charging starts when the system and the computer are connected.
Make sure that the BATT/CHG indicator (orange) lights up. Charging is completed in about 3 hours* and the BATT/CHG indicator (orange) goes off automatically.
* Time required to charge the empty battery to its full capacity
  • If the system is not used for a long time, the BATT/CHG indicator (orange) may not light up when you connect the micro-USB cable to charge the system. In this case, do not disconnect the micro-USB cable from the system and wait until the BATT/CHG indicator (orange) lights up.

  • By connecting the system to a computer via USB, you can charge the system, but cannot play music.

  • To charge the system from an AC outlet, use a USB Charging AC Power Adaptor (sold separately). For details, refer to the manuals supplied with the USB Charging AC Power Adaptor.

If the system detects a problem while charging, the BATT/CHG indicator (orange) may turn off, although charging is not complete.
Check for the following causes:
  • Ambient temperature exceeds the range of 5 °C – 35 °C (41 °F – 95 °F).

  • There is a problem with the battery.

    In this case, charge again within the above-mentioned temperature range. If the problem persists, consult your nearest Sony dealer.
  • Charging time varies depending on conditions of use of the battery.

  • Charge the system in the ambient temperature between 5 °C and 35 °C (41 °F and 95 °F).

  • Charging the system using the computer you assembled or converted is not guaranteed to work.

  • If you connect the system to a laptop computer that is not connected to a power source, the laptop computer battery will discharge faster than normal.

  • The system will get warm during charging. This is not a malfunction.

  • Even if you do not intend to use the system for a long time, charge the battery to its full capacity once every 6 months to maintain its performance.

  • If the system is not used for a long time, it may take longer to charge the battery.

  • If the life of the built-in rechargeable battery drops to half the normal length, the battery should be replaced. Consult your nearest Sony dealer for replacement of the rechargeable battery.

  • Avoid exposure to temperature extremes, direct sunlight, moisture, sand, dust or mechanical shock. Never leave the system in a car parked in the sun.

  • Use the supplied micro-USB cable only, and connect directly to a computer. Charging will not be completed properly by an indirect connection, such as via a USB hub.

Battery life (when using the BLUETOOTH connection)
