Postavljanje i instalacija
1. Punjenje zvučnika
Before first use, fully charge the speaker. Connect the provided USB charging cable to the speaker's charging port and a 5V/1000mA USB power adapter (not included). The charging indicator will typically show charging status and turn off or change color when fully charged.
2. Uključivanje/isključivanje
To power on the speaker, long press the power button until you hear an audible indication or see the power indicator light up. To power off, long press the power button again until the indicator turns off.
3. Bluetooth uparivanje
- Ensure the speaker is powered on and in Bluetooth mode (it usually defaults to Bluetooth mode upon startup). The Bluetooth indicator will flash, indicating it's ready for pairing.
- Na svom uređaju (pametnom telefonu, tabletu itd.) omogućite Bluetooth i potražite dostupne uređaje.
- Izaberite "TG668" sa liste pronađenih uređaja.
- Once paired, the speaker will emit a confirmation sound, and the Bluetooth indicator will stop flashing and remain solid.
4. Uparivanje sa pravim bežičnim stereo sistemom (TWS) (opciono)
To pair two TG668 speakers for TWS stereo sound:
- Provjerite jesu li oba zvučnika uključena i nisu povezana ni sa jednim Bluetooth uređajem.
- On one speaker (this will be the primary speaker), long press the TWS button (often the Play/Pause button or a dedicated TWS button, refer to the control diagram).
- The speaker will search for another TG668 speaker. Once found, they will automatically pair, and you will hear a confirmation sound.
- Connect your device to the primary speaker via Bluetooth as described in step 3. Both speakers will now play audio in stereo.
