3.1 Charging the Devices

Before first use, fully charge both the voice amplifier and the wireless microphone headset.

1. Connect the charging cable to the DC 5V port on the voice amplifier. Connect the other end to a USB power adapter (not included) or a computer USB port. The charging indicator light will illuminate.
2. Connect the other charging cable to the wireless microphone headset's charging port. Connect the other end to a USB power adapter or computer USB port.
3. Allow approximately 3-4 hours for the amplifier and 3 hours for the microphone to fully charge. The indicator lights will change or turn off once charging is complete.

3.2 Pairing the Wireless Microphone

The wireless microphone and amplifier are typically pre-paired from the factory. If they do not connect automatically, follow these steps:

1. Turn on both the voice amplifier and the wireless microphone headset.
2. Ensure both devices are within close proximity (e.g., 1 meter).
3. The microphone should automatically connect to the amplifier. A successful connection is usually indicated by a stable blue light on the microphone.
4. If pairing fails, refer to the Troubleshooting section or consult the specific pairing instructions in the included quick start guide.
