- The cord is designed for indoor use only. Do not expose it to moisture or extreme temperatures.
5. Maintenance
Proper maintenance ensures the longevity and safe operation of your power cord:
- Cleaning: Disconnect the power cord from both the device and the wall outlet before cleaning. Wipe the cord with a dry, soft cloth. Do not use liquid cleaners or abrasive materials.
- Inspection: Periodically inspect the power cord for any signs of damage, such as cuts, fraying, exposed wires, or bent prongs. If damage is found, discontinue use immediately and replace the cord.
- Storage: When not in use, store the power cord in a cool, dry place, away from direct sunlight and extreme temperatures. Avoid tightly wrapping the cord, which can cause internal damage.
6. Troubleshooting
If you encounter issues with your YUSTDA AC Power Cord, consider the following:
- No Power to Device:
- Ensure both ends of the power cord are securely plugged into the device and the wall outlet.
- Check if the wall outlet is functional by plugging in another device.
- Verify that the device's power switch is in the 'ON' position.
- Inspect the power cord for visible damage. If damaged, replace it.
