Maintenance
Regular maintenance ensures the longevity and optimal performance of your charging locker.
- Cleaning: Use a soft, dry cloth to wipe down the exterior surfaces. For stubborn marks, a slightly damp cloth with mild detergent can be used, followed by drying. Do not use abrasive cleaners or solvents.
- Ventilation: Periodically check that the ventilation openings are clear of dust and debris to ensure proper airflow and prevent overheating.
- Cable Management: Ensure internal cables are neatly arranged and not tangled or damaged. Replace any frayed or damaged cables immediately.
- Lock Mechanism: Keep the lock mechanisms clean. If the lock becomes stiff, a small amount of graphite lubricant can be applied.
Troubleshooting
| Problem | Possible Cause | Solution |
