# GENERAL

## Warnings

{% hint style="warning" %}

* When not in use, always **store the ORUS-L series in its designated storage case**. Replace the **desiccant pack** as needed to prevent **lens fogging caused by high humidity**. If fogging occurs, it will typically clear after the device has been powered on for a short period.\
  → Recommended storage conditions: **humidity < 40%** and **temperature 20 ± 5°C**.
* **Avoid exposing** the infrared camera lens to high-energy sources such as direct sunlight, lava, or laser beams. Exposure may cause irreversible damage to the infrared sensor.
* **Ensure that** the observed target temperature remains below 800°C (1472°F), or 1600°C (2912°F when an infrared density filter is installed). Exceeding these limits may result in permanent sensor failure.
* **Refrain** from placing the product in direct sunlight, poorly ventilated environments, or near heat sources (e.g., heaters), as this may affect performance and durability.
* **Avoid frequent power cycling**. After powering down, allow at least 30 seconds before restarting to prevent potential damage and reduced product lifespan.
* **Prevent liquid ingress** into the product. Ensure the surface and all ports of the gimbal are completely dry prior to installation.
* **Avoid direct contact** with the lens surface. Take care to prevent scratches from sharp or abrasive objects, as these may degrade image quality.
* **Use only** a soft, dry, and clean cloth for lens cleaning. Refrain from using alkaline or corrosive cleaning agents.
* **Handle the product with care.** Mechanical shock, dropping, or impact may result in malfunction.
* **Note that** the IP55 protection rating (per IEC 60529) is validated under controlled laboratory conditions and may degrade over time with use and environmental exposure.
* **Be aware that** the use of an infrared density filter may affect thermal image quality.

#### **Product Profile**

**Orus-L** is a specialized payload developed by **Gremsy**, designed with a **spherical aerodynamic shape** and rated **IP55** for water and dust resistance. Built to endure harsh environments, including dust, humidity, and light rain, Orus-L remains stable even at speeds up to **100 km/h**. It's an ideal choice for **high-speed UAVs** and **demanding missions**.

## 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.

{% hint style="success" %}
Recommendation: Use a dry cabinet to keep temperature and humidity stable and well-controlled.
{% endhint %}

### 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.     |

{% hint style="danger" %}
**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.
  > {% endhint %}

### 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
