5. Operating Instructions
Once the extension cords are securely connected between the power adapter and the Inwa MZ-511 speaker, the speaker will receive power as usual. No special operation is required for the extension cords themselves. Ensure all connections remain tight for optimal performance and waterproofing.

- Inspection: Periodically inspect the cords for any signs of wear, damage, or fraying. Check the rubber sealing rings for integrity.
- Storage: When not in use, coil the cords neatly and store them in a dry place away from direct sunlight and extreme temperatures.
- Waterproofing: Ensure the threaded connections are always tightly secured to maintain the waterproof seal, especially when used outdoors.
7. Troubleshooting
- Speaker Not Powering On:
- Verify that the extension cords are correctly and securely connected to both the power adapter and the speaker.
- Ensure the power adapter is plugged into a functional power outlet.
