# Maintenance and service

### Cleaning

- Always disconnect the Meteor Pro from power before cleaning.
- Use a soft, dry cloth or, if necessary, a slightly damp cloth with clean water.
- Do not use solvents, alcohol, or abrasive cleaners — they may damage the enclosure or seals.
- Ensure that no moisture enters the USB-C connector, antenna port.

---

### Regular inspection

To maintain reliability and safety, perform periodic checks:

- Inspect the USB-C connector for corrosion or wear.
- Verify that the antenna connector is tight and undamaged.
- Check the enclosure seals and gaskets for signs of deterioration (especially after outdoor use).
- Confirm that the indicator LED and communication functions operate as expected.

---

### Battery maintenance

- The internal battery is a Li-ion NCR-18650BF 3.6 V / 3350 mAh cell.
- Battery replacement should only be carried out by Nomadstar SARL or authorized personnel to maintain water-resistance and compliance.
- Do not puncture, disassemble, short-circuit, or expose the battery to fire or high temperatures.
- If the device shows signs of swelling, heat, or leakage, discontinue use immediately and contact support.

### Service and repairs

<p class="callout danger">**Do not open or modify** the Meteor Pro yourself.  
Opening the enclosure voids the warranty and may compromise safety or compliance.</p>

### Storage

- Store the unit between –20 °C and +60 °C in a dry environment.
- For long-term storage, charge the battery to 50 % and recharge it every 6 months to maintain performance.

### Residual Risks

Despite all protective measures taken during design and manufacturing, some risks cannot be entirely eliminated:
