Checking the charging completion
If the built-in battery is fully charged when you connect the speaker to an AC outlet, the CHARGE indicator lights up in
orange then turns off after about 1 minute.
Checking the built-in battery level of the rechargeable built-in battery
After pressing the BATT (battery) button/
LIGHT button inside the cap on the rear side of the speaker, when the
speaker is turned on, the voice guidance listed below is output from the speaker depending on the remaining built-in
battery power.
70% or more: “Battery fully charged”
50% or more: “Battery about 70%”
20% or more: “Battery about 50%”
10% or more: “Battery about 20%”
Less than 10%: “Please charge”
Lithium-ion battery life (with playback via a BLUETOOTH connection)
About 24 hours
The volume level of the speaker is set to 26.
The lighting function is set to off.
The Sound Mode is set to STANDARD.
About 14 hours
The volume level of the speaker is set to 26.
The lighting function is set to on. (factory default settings)
The Sound Mode is set to EXTRA BASS. (factory default settings)
About 4 hours
The volume level of the speaker is set to maximum (50).
The lighting function is set to on.
The Sound Mode is set to EXTRA BASS.
If the built-in lithium-ion battery is running low, the maximum volume is reduced to about half to protect the circuit.
This is a specification.
The usage life mentioned here also includes when playing back music at about half the volume.
The built-in battery life above is measured using the specified music source.
Actual performance time may vary from the listed time due to the volume, songs played, surrounding temperature, and
usage conditions.
When the built-in battery is running low
When the voice guidance says “Please charge” and the CHARGE indicator and
(power) indicator flash slowly, the
built-in battery is running low and needs to be charged. In this state, the speaker cannot supply power to other devices.
Hint
You can also charge the speaker by connecting it to a booted computer via the micro-USB cable. However, operation with all
computers is not guaranteed. Operation with a home-built computer is also not covered by the warranty.
A speaker that is in use can be charged if it is connected to an AC outlet via the AC adaptor (supplied) or an USB AC adaptor
(commercially available), or if connected to a booted computer. In this case, it may take longer to charge the built-in battery
compared to when the speaker is turned off depending on the conditions of use. Therefore, it is recommended to turn off the
speaker when charging.
The estimated charging time differs depending on the power output capacity of the connected USB AC adaptor
(commercially available). Depending on the type and specification of the USB AC adaptor and micro-USB cable,
the charging time may take longer than the time stated below. The time stated below may vary depending on the
ambient temperature or conditions of use.
The following time is stated as the reference time.
When connecting to a USB AC adaptor (commercially available) which has the ability to output in 1.5 A:
Charging will be completed in about 8 hours*2, and the CHARGE indicator will turn off.
Time that is required to charge the empty built-in battery to its full capacity when the speaker turns off.
