If you suspect that the product is interfering with your medical device, stop using the product immediately.

4. Installation and Operation

Power Supply

Before powering on the product, make sure the electrical interfaces are dry and clean. Do NOT power on the product in humid conditions.
Do NOT use out-of-spec or damaged cables or adapters.
You are recommended to use only the cables and power adapters provided by Hesai. If you are to design, configure, or select the power supply system (including cables) for the product, make sure to comply with the electrical specifications in the product's user manual (refer to the Specifications section and the Power Supply Requirements section of the product's user manual if available); for technical support, please contact Hesai.
Please check the Electrical interface section of the product's user manual and strictly follow the instructions on plugging/unplugging the connector. If abnormalities already exist (such as bent pins, broken cables, and loose screws), stop using the product and contact Hesai technical support.

Eye Safety

This product is developed according to IEC 60825 Class 1; the specific certification information is provided either on the product's nameplate or as otherwise agreed to.

For maximum self-protection, it is strongly warned NOT to look into the transmitting laser through a magnifying product (microscope, eye loupe, magnifying glass, etc.).
This product does not have a power switch. It starts operating once connected to power. During operation, the entire cover lens (or optical window) can be regarded as the product's laser emitting window; looking at the cover lens (or optical window) can be regarded as looking into transmitting laser.

Product Enclosure

The product contains metal, glass, plastic, as well as sensitive electronic components. In the event that the product is dropped or burnt, stop using it immediately and contact Hesai technical support.
Do NOT squeeze or pierce the product. If the product enclosure is broken, stop using it immediately and contact Hesai technical support.
Certain product models contain high-speed rotating parts. To avoid potential injuries, do NOT operate the product if the enclosure is loose.
Before operating the product, make sure it is properly and securely mounted. The mounting should prevent the product from leaving its mounting position under external forces (such as collisions, high winds, and stone impacts).
If the product enclosure consists of fins or grooves, please wear gloves when handling the product. Applying too much pressure with your bare hands may cause cuts, bruises or other injuries.

Cover Lens or Optical Window

Do NOT apply protective film, wax, or any other substance on the cover lens (or optical window).
To keep the product's cover lens (or optical window) from fingerprints and other stains, do NOT touch the cover lens (or optical window) with bare hands. If it is already stained, please refer to the cleaning method in the Maintenance section of the product's user manual.
To prevent scratches, do NOT touch the product's cover lens (or optical window) with hard or sharp objects. If scratches already exist, stop using the product and contact Hesai technical support. Severe scratches may affect the quality of the product's point cloud data.

NOTE: The location of the cover lens or optical window is illustrated in the Introduction section in the product's user manual.

Mounting

Before operating the product, make sure it is properly and securely mounted. The mounting should prevent the product from leaving its mounting position under external forces (such as collisions, high winds, and stone impacts).
Before installing any exterior part, please ensure that each exterior part and its movable area do not overlap the Field of View (FOV) of the lidar.

NOTE: The FOV of a lidar is the spatial angular range bounded by the horizontal and vertical FOV angles (see the Specifications section of the product's user manual); the distance to the origin of the lidar's coordinate system is not limited. For questions about the FOV, please contact Hesai technical support.

Hot Surface

During operation or a time period after operation, the product's enclosure can be hot.

To prevent discomfort or even burns, do NOT touch the product's enclosure with your skin.
To prevent fires, keep flammable materials away from the product's enclosure.

Certain product models support active heating of the cover lens (or optical window) to reduce the impact of ice and frost. Users can turn off this function.

While active heating is ON, please avoid direct skin contact with the cover lens (or optical window).
For the location of the cover lens (or optical window), please refer to the Introduction section in the product's user manual.
