Avoid storing equipment in direct sunlight or near heating devices to prevent malfunctions caused by high internal temperatures; When storing, prevent the device from condensing, and when transporting to the storage location, also be careful to avoid sudden temperature changes that may cause condensation.

Do not store equipment in environments with high dust, smoke, or chemical gases to prevent performance degradation or malfunction; When the device is not in use, a protective cover should be installed to prevent dust from entering the integrating sphere and affecting the measurement accuracy; Do not let the device have the target mask installed for a long time; Do not leave the device in the driver's cabin or trunk of the vehicle to prevent malfunctions caused by temperature and humidity exceeding the allowed storage range.

The white calibration board may change color when exposed to light, and should be covered when not in use; The target mask may change color when exposed to light. When not in use, it should be stored in the accessory storage space of the device to avoid light exposure, scratches, and dust accumulation; When the equipment is not in use for a long time, it should be stored properly in the transport packaging; When operating the opening and closing parts of the attachment storage space, be careful not to pinch it.

（2） Cleaning precautions

When the surface of the equipment is dirty, wipe it with a soft dry cloth, and do not use organic solvents (such as naphtha, diluents) or other chemical reagents for cleaning.

When there is dust or dirt on the lens or receiver window, use a dust blower to remove it, and do not use organic solvents or other chemical reagents; When the interior of the white calibration board, zero calibration box, or target mask (except for the inner white coating surface) is dirty, use a soft, clean dry cloth to wipe it. For dirt that is difficult to remove, use a cloth dipped in ethanol to wipe it. After the cloth is dirty, it needs to be cleaned. Organic solvents or other chemical reagents are prohibited from being used.

When the surface of the white coating on the inside of the target mask or the inside of the integrating sphere is dirty, it is necessary to contact an authorized service agency; If the above methods cannot remove dirt or equipment scratches, contact an authorized service agency; When the equipment malfunctions, it is prohibited to disassemble and repair it on your own, and authorized service agencies must be contacted.
