- On your device (smartphone, tablet, etc.), enable Bluetooth and search for available devices.
- Select "TG447" from the list of devices.
- Once connected, the speaker will emit a confirmation sound, and the LED light will change its state (e.g., solid blue or slow pulse).
The speaker uses Bluetooth 5.3 technology, offering a stable wireless transmission range of up to 10 meters with low latency.
4.4 TWS (True Wireless Stereo) Interconnection
The TG447 speaker supports TWS function, allowing you to pair two TG447 speakers together for a true stereo sound experience.
- Ensure both TG447 speakers are powered on and not connected to any other Bluetooth device.
- On one of the speakers (this will be the primary speaker), press and hold the TWS button (often indicated by two interlocking circles or a similar symbol) for a few seconds.
- The speakers will search for each other and automatically pair. A confirmation sound will indicate successful TWS connection.
- Once TWS is established, connect your device to the primary speaker via Bluetooth as described in section 4.3. Audio will now play through both speakers in stereo.
