Turning the power on

When using the headphone amplifier for the first time, charge its battery beforehand.

Connect the headphone amplifier to your booted computer using the micro-USB cable (supplied).

  1. Rotate the power/volume knob clockwise.

    The CHG POWER indicator flashes in green then lights up.

    Rotate the power/volume knob further clockwise to increase the volume.

Hint

  • Just after the headphone amplifier is turned on, you can check the battery level by the number of times the CHG POWER indicator flashes in green.
    • Flashes three times (green): Substantially charged
    • Flashes twice (green): Half charged
    • Flashes once (green): Battery level is low. It is necessary to charge the battery.
    • Continuous flashing (orange): It is necessary to charge the battery. If you continue to use the headphone amplifier without charging, it will turn off automatically.
