Connecting to an AC outlet

The speaker can be operated by connecting it to an AC outlet via AC adaptor (supplied) or built-in battery (rechargeable).

Charge the battery before using the speaker for the first time.

Connect the AC adaptor (supplied) to the DC IN 15 V jack.
Plug the AC adaptor to an AC outlet.

Charging starts and the CHARGE indicator lights up in orange. Charging is completed in about four hours^*1 and the indicator turns off. Once the battery is fully charged, it will not be charged furthermore even if the speaker is kept connected to an AC outlet.

^*1 Time that is required to charge the empty battery to its full capacity.

About 10 hours^*2.

The time stated above may vary depending on ambient temperature or conditions of use.

^*2The method of estimating the battery life has been changed since 2015.

When the CHARGE indicator flashes slowly in orange, the battery is running low and needs to be charged. In this state, the speaker cannot supply power to other devices.
If the CHARGE indicator flashes three times in orange and turns off when you turn on the speaker, the battery is empty and needs to be charged.

When you switch the power source between an AC outlet and battery by connecting/disconnecting the AC adaptor, the speaker may stop sound output for a short while. This is not a malfunction.
The maximum power output will be lower when the AC adaptor is disconnected from an AC outlet.
In an extremely cold or hot environment, charging stops for safety. Try to charge the battery again within the operating temperature of between 5 °C and 35 °C (41 °F and 95 °F).
Even if you do not intend to use the speaker for a long time, charge the battery to its full capacity once every six months to maintain its performance.
