4. Operating Instructions
4.1 Bluetooth Pairing
Once powered on, the speaker will automatically enter Bluetooth pairing mode, indicated by a flashing blue light. To connect:
- Ensure Bluetooth is enabled on your device (smartphone, tablet, laptop, Echo Dot, etc.).
- Search for "Dosmix M3" or a similar name in your device's Bluetooth settings.
- Select the speaker from the list to pair. Once successfully paired, the blue indicator light will typically become solid, and you may hear a confirmation tone.
The speaker is compatible with Bluetooth version 2.1 and above.
4.2 Wireless Stereo Pairing (TWS)
To achieve a true wireless stereo experience, you can pair two Dosmix M3 speakers together:
- Ensure both Dosmix M3 speakers are powered off.
- Power on both speakers simultaneously. They will automatically attempt to pair with each other.
- Once successfully paired with each other, one speaker will act as the master and the other as the slave. The master speaker will then be discoverable by your Bluetooth device.
- Connect your device to the master speaker as described in Section 4.1.
