Care and Maintenance
- Cleaning: Disconnect the power cord from both the wall outlet and the device. Wipe the cord with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Storage: When not in use, coil the power cord loosely. Avoid tight coiling or bending, which can damage the internal wires. Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Regular Inspection: Periodically inspect the entire length of the cord, including the connectors, for any signs of wear, cuts, or damage. Replace the cord immediately if any damage is found.
