Setup
1. Charging the Speaker
Before first use, fully charge the speaker. Connect the provided USB charging cable to the speaker's charging port and the other end to a 5V/1A USB power adapter (not included) or a computer's USB port. The charging indicator light will illuminate during charging and turn off or change color once fully charged. A full charge takes approximately 1.5 hours.
2. Powering On/Off
- To Power On: Press and hold the power button (usually indicated by a power symbol) for a few seconds until you hear an audible prompt or see the indicator light flash.
- To Power Off: Press and hold the power button again for a few seconds until you hear an audible prompt or the indicator light turns off.
Operating Instructions
1. Bluetooth Pairing
- Ensure the speaker is powered on and in Bluetooth pairing mode (the indicator light will typically flash rapidly).
- On your mobile device (smartphone, tablet, computer), enable Bluetooth and search for available devices.
- Select "AWEI Y666" from the list of found devices.
- Once paired, the speaker will emit an audible confirmation, and the indicator light will typically stop flashing and remain solid.
2. TWS (True Wireless Stereo) Interconnection
To achieve 360° surround sound, you can connect two AWEI Y666 speakers:
- Ensure both Y666 speakers are powered on and not connected to any other Bluetooth device.
- On one of the speakers, double-press the power button (or a dedicated TWS button if available, refer to specific button layout on your device) to initiate TWS pairing.
- The two speakers will automatically search for and connect to each other. You will hear an audible confirmation once connected.
- Once TWS is established, connect your mobile device to one of the speakers via Bluetooth as described in the "Bluetooth Pairing" section. Both speakers will then play audio in stereo.
3. Basic Controls
The speaker typically features intuitive controls:
- Power Button: Long press to power on/off. Short press for play/pause (when playing music).
- Volume Up/Next Track: Short press for volume up. Long press for next track.
