Charging the battery via a computer

The headphone amplifier contains a rechargeable lithium-ion battery, which should be charged before using it for the first
time.
1. Rotate the power/volume knob counterclockwise, until it clicks, to turn off the headphone amplifier.
The battery charges only when the headphone amplifier is off. Rotate the power/volume knob clockwise to turn on
the headphone amplifier. Rotate it more to adjust the volume.
2. Connect your booted computer to the DC IN 5V port of the headphone amplifier using the micro-USB cable
(supplied).
The POWER/CHG indicator lights up in red while the battery is being charged, and the indicator turns off when
charging is completed.
Charging is completed in about 15 hours.
If the battery is not charged properly, the POWER/CHG indicator will flash in red.
