After charging, it keeps lighting up green. ⑤ Power LED: after turning on the amplifier, this LED keeps lighting up green. It keeps lighting up red during low power voltage. After lighting up for

45 minutes, the amplifier turns off automatically and the LED lights off. ⑥ Power switch/volume knob: turn it clockwise. When you hear the sound DA, the headset amplifier turns on and power LED lights up. Continue to turn knob clockwise to increase volume. Turn knob counterclockwise to decrease volume. Continue to turn it fully. You hear the sound DA. The headset amplifier turns off and power LED lights off. ⑦ BASS switch:ON(boost the bass),OFF (bypass mode). HA
