Operating Instructions
1. Power On/Off
- To power on: Press and hold the Power button until the speaker activates. You may hear a "tech" mech voice prompt.
- To power off: Press and hold the Power button until the speaker deactivates.
2. Bluetooth Pairing
- Ensure the speaker is powered on and in Bluetooth pairing mode (indicated by a flashing LED).
- On your device (smartphone, tablet, computer), enable Bluetooth and search for available devices.
- Select "TF-Y17Pro" from the list of devices.
- Once paired, the speaker will indicate a successful connection, and the LED will stop flashing.
3. TWS (True Wireless Stereo) Pairing
To achieve a wider stereo soundstage, you can pair two TF-Y17Pro speakers together:
- Ensure both TF-Y17Pro speakers are powered on and not connected to any other Bluetooth device.
- On one of the speakers, press the "M" button (Mode button) to initiate TWS pairing. It will search for another TF-Y17Pro speaker.
- The two speakers will automatically connect to each other. Once connected, one speaker will act as the master (left channel) and the other as the slave (right channel).
- Now, connect your device to the master speaker via Bluetooth as described in step 2.
4. TF Card Playback
Insert a TF (microSD) card loaded with audio files into the designated TF card slot on the speaker. The speaker will automatically switch to TF card playback mode. Use the control buttons to navigate tracks.
5. Hands-Free Calling
When connected to your smartphone via Bluetooth, the speaker can be used for hands-free calls. Incoming calls will be routed through the speaker. Use the control buttons to answer or end calls.
6. RGB Lighting Effects
The speaker features dynamic RGB ambient lighting. The lighting effects are synchronized with sound. Specific controls for changing or turning off RGB lighting may vary; refer to the device's physical buttons or any associated app if available.
7. Volume Control
Use the '+' and '-' buttons on the speaker to adjust the volume. You can also control the volume from your connected device.
