5. Maintenance and Care
- Cleaning: Use a dry, soft cloth to wipe the cable and connectors. Do not use liquid cleaners or solvents.
- Storage: When not in use, coil the cable loosely. Avoid tight coiling or kinking, which can damage the internal wires. Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Inspection: Periodically inspect the cable for any signs of wear, cuts, or damage to the insulation. If damage is observed, discontinue use and replace the cable.
- Environmental Conditions: While the cable is durable, avoid exposing it to harsh weather conditions or environments with excessive moisture or dust unless specifically rated for such use.
6. Troubleshooting
