- Monitor your speaker's charging indicator (if available) to confirm it is receiving power.
5. Maintenance and Care
- Cleaning: Disconnect the adapter from both the power outlet and the speaker before cleaning. Use a soft, dry cloth to wipe the surface. Do not use liquid cleaners or aerosols.
- Storage: Store the adapter in a cool, dry place when not in use. Avoid wrapping the cord too tightly around the adapter to prevent damage to the cable.
- Inspection: Periodically inspect the adapter and its cable for any signs of damage, such as cuts, frayed wires, or bent pins. If damage is found, discontinue use immediately.
6. Troubleshooting
- No Power to Speaker:
- Ensure the adapter is securely plugged into both the speaker and a working wall outlet.
- Test the wall outlet with another device to confirm it has power.
