2. Charging the Speaker

- On your device (smartphone, tablet, etc.), navigate to the Bluetooth settings.
- Select "Retro Bluetooth Speaker" from the list of available devices.
- Once connected, you will hear a confirmation sound from the speaker, and the indicator light will become solid.

Maintenance
1. Cleaning
Wipe the speaker with a soft, dry cloth. Do not use abrasive cleaners, solvents, or harsh chemicals. Avoid getting moisture into any openings.
2. Storage
When not in use for extended periods, store the speaker in a cool, dry place away from direct sunlight and extreme temperatures. Ensure the battery is partially charged before storage to prolong its lifespan.
Troubleshooting
- No Power: Ensure the speaker is charged. Connect it to a power source and check the charging indicator.
- Cannot Pair: Make sure the speaker is in pairing mode (flashing indicator light). Turn off Bluetooth on other nearby devices that might be trying to connect. Restart both the speaker and your device.
- No Sound: Check the volume levels on both the speaker and your connected device. Ensure the device is properly paired and playing audio.
- Sound Distortion: Move the speaker closer to your device to ensure a strong Bluetooth connection. Reduce the volume if it's too high.
- Lag in Audio/Video Sync: While the speaker is optimized for audio, some devices or applications may experience slight audio-video synchronization delays. This is often due to the source device or application and not the speaker itself.
