Connecting to an AC outlet

You can operate the speaker by connecting to the AC outlet with the supplied USB AC adaptor or by using the built-in lithium-ion battery (rechargeable).

Before using the speaker for the first time, be sure to charge the battery by connecting the speaker to an AC outlet via the supplied USB AC adaptor and micro-USB cable.

When connecting the micro-USB cable to the DC IN 5 V jack, the (power) indicator starts flashing in green after about two seconds, and then the speaker enters the start-up mode. It takes about 15 to 30 seconds. After that, the (power) indicator is lit in red (standby mode), and you can turn on the speaker.*1

When the battery is charged, you can use the speaker without using the USB AC adaptor.

*1For the protection of the battery, the (power)/ PAIRING button is locked when shipping.

  1. Connect the supplied USB AC adaptor and micro-USB cable.
  2. Connect the micro-USB cable to a DC IN 5 V jack.
  3. Connect the USB AC adaptor to an AC outlet.

    Do not use other than the supplied USB AC adaptor, micro-USB cable, and AC power cord.

    When the speaker is connected to an AC outlet via the USB AC adaptor, charging starts and the CHARGE indicator lights up in orange. Charging is completed in about 3 hours*2 and the indicator turns off.

    *2When the speaker is turned off, time that is required to charge the empty battery to its full capacity.

If a AC power cord or conversion adaptor is supplied

The shape of the plug on the USB AC adaptor and the connection method differ. According your country or region, connect the AC power cord and conversion adaptor to the USB AC adaptor.

Lifespan of a lithium-ion battery

When making a BLUETOOTH (SBC) connection: Approx. 12 hours (at normal playback)*3

When connected to a network: Approx. 8 hours (at normal playback)*4

*3When the specified music source is used, the BLUETOOTH device is set to the maximum volume, and the volume level of the speaker is set to 33.
The battery life when the volume level of the speaker is set to maximum will be 4 hours.

*4When the specified music source is used, the network device is set to the maximum volume, and the volume level of the speaker is set to 33. The battery life when the volume level of the speaker is set to maximum will be 4 hours.

When the battery is running low

When the CHARGE indicator flashes slowly, the battery is running low and needs to be charged. Charge the speaker by connecting to an AC outlet via the USB AC adaptor.

Hint

  • Even when listening to music from the speaker, you can charge the speaker if it is connected to the AC outlet. (The CHARGE indicator is not lit.) However, it is recommended to turn off the speaker for charging because the charging time may become longer.

Note

  • Charge the battery before use.
    • When connecting the USB AC adaptor to the speaker for the first time, the (power) indicator flashes slowly in green for about 20 to 30 seconds, and then it lights up in red. Unless the (power) indicator lights up in red, the speaker is not turned on by pressing the (power)/ PAIRING button.
    • Charge the battery before use, otherwise the power will not turn on. If the battery life is low, the speaker is not turned on immediately even when connected the USB AC adaptor.
    • Charge the battery at least 1 hour before use.
  • When the speaker is turned on, the CHARGE indicator is not lit even when the USB AC adaptor is connected. (Charging is started.)
  • When you switch the power source between an AC outlet and battery by connecting/disconnecting the USB AC adaptor, sound output will stop for a short while. This is not a malfunction.
  • If you use the speaker at a high volume, the battery power and the volume may reduce even when connected to an AC outlet. When using the speaker while charging the battery, turn the volume to low. Or turn off the speaker, and wait until the battery is charged fully.
  • If you use the speaker at a high volume for a long time, the battery power and the volume may reduce even when connected to an AC outlet. This is not a malfunction. In this case, turn off the speaker, and wait until the battery is charged fully.
  • When the battery life is low (CHARGE indicator flashes), the maximum output level of the speaker becomes low.
  • In a very high or low temperature, charging the battery will be stopped for its safety. If the charging continues for a long time, the charging may be stopped. Charge the battery in the usable temperature range (5 °C to 35 °C).
  • If you do not intend to use the speaker for a long time, charge the battery to its full capacity once every 6 months to maintain its performance.
