## Caution

TOPODRONE Sony ILX-LR1 with LR1 Control Module is a photogrammetric system for aerial survey with data processing in TOPODRONE software. The system consists of the Sony ILX-LR1 industrial full-frame camera (61 MP, mechanical shutter), the DJI X-Port 3-axis gimbal and the TOPODRONE LR1 Control Module with a built-in survey-grade GNSS receiver. The system obtains high-precision coordinates of the camera centers in two modes: PPK - from raw satellite measurements that the receiver records to a microSD memory card, and RTK - from corrections of the RTK module built into the DJI drone.

> **Warning:** DO NOT store the equipment in direct sunlight, in poorly ventilated places or near a heat source.

> **Warning:** Avoid direct sunlight entering the camera lens.

> **Warning:** DO NOT turn the equipment on and off for short periods. Wait at least 30 seconds before turning it on or off again.

> **Warning:** The equipment is not protected against moisture and dust, so use in a humid or dusty environment may cause malfunction.

> **Danger:** When the equipment is not in use, store it in the protective case. It is recommended to store the equipment at a relative humidity of no more than 40% and a temperature of 20±5°C.

> **Warning:** DO NOT insert or remove memory cards while the camera and the LR1 Control Module are operating.

> **Warning:** Do not touch the lens surface with your hands or sharp objects - you can damage the coating, which degrades image quality.

> **Warning:** DO NOT detach the lens while the camera is operating.
