5. Maintenance
To ensure the longevity and optimal performance of your BUGANI M99 speakers, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the speaker's surface. Do not use abrasive cleaners or solvents.
- Water Resistance: The speakers feature an IPX5 waterproof rating, meaning they are protected against low-pressure water jets from any direction. They are suitable for use in environments like poolside or during light rain. Do not submerge the speakers in water.
- Storage: Store the speakers in a cool, dry place away from direct sunlight and extreme temperatures when not in use for extended periods.
- Battery Care: To preserve battery life, avoid fully discharging the speakers frequently. Charge them regularly, even if not in constant use.
6. Troubleshooting
If you encounter issues with your BUGANI M99 speakers, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Speakers do not turn on. | Low battery. | Charge the speakers fully using the provided Type-C cable. |
| Cannot pair speakers in TWS mode. | Incorrect pairing procedure or speakers too far apart. | Ensure both speakers are on and close to each other. Rapidly double-press the Play/Pause button on only one speaker. Refer to Section 4.1. |
| No sound or low volume. | Volume too low on speaker or device; device not connected. | Increase volume on both the speaker and your connected device. Ensure Bluetooth is connected (solid white light). |
| Bluetooth connection unstable or drops. | Device too far from speakers; interference. | Move your device closer to the speakers (within 100 feet). Avoid obstacles or other strong wireless signals. |
| Sound only comes from one speaker in TWS mode. | TWS pairing not successful or device connected to only one speaker. | Repeat the TWS pairing steps (Section 4.1). Ensure your device is connected to the primary speaker (the one with the solid white light after TWS pairing). |
