Storage Conditions

Recommended Storage Environmental Conditions

When not in use, GREMSY payloads shall be stored under the following conditions:

• Ambient Temperature: 18–25°C

• Relative Humidity: 30 – 45 %RH

These conditions are recommended to ensure long-term reliability of electronic components, gimbal motors, camera sensors, and mechanical assemblies.

Recommendation: Use a dry cabinet to keep temperature and humidity stable and well-controlled.

Storage Requirements Based on Non-Operating Duration

Non-Operating Duration	Storage Requirement
≤ 12 hours	Should be stored under the recommended storage conditions.
> 12 hours	Must be stored under the recommended storage conditions.
Long-term storage / standby	Always store under the recommended storage conditions.

Warning: If the device is not maintained under the recommended storage conditions

• 12-72 hours: condensation on the sensor lens may occur.

• 72 hours: there is a high risk of moisture-related damage.

Important Notes

In high-humidity environments (80–90% RH), dry cabinet storage may be required sooner than the time frames listed above.

Failure to follow these storage conditions may result in:

1. PCB oxidation and corrosion

2. Reduced gimbal motor lifespan

3. Electrical connector and camera sensor malfunction
