5. Operating Instructions
The B18 Translator Earbuds offer four distinct translation modes, each suited for different communication scenarios. These modes are typically managed through the companion application.

5.1 Translation Modes
- Touch Mode:
Suitable for acquaintances who are willing to wear an earphone. Two people each wear an earbud. Click the earbud to speak, and it will translate in real-time for the other person.
Figure 6: Touch Mode in use - Speaker Mode:
Ideal for situations with strangers or when it's inconvenient for the other person to wear an earphone. One person wears the earbuds, and the other person holds the mobile phone. The translation will be played through the phone's speaker.
Figure 7: Speaker Mode in use - Free Talk Mode:
Designed for hands-free, real-time communication between two people. Each person wears an earbud, and the device translates continuously as you speak, allowing for natural conversation flow.
Figure 8: Free Talk Mode in use - Offline Mode:
Allows translation without an internet connection for supported languages (e.g., Chinese, English, Japanese, Korean, Russian, German, French, Spanish). Ensure the necessary language packs are downloaded via the app beforehand.
