● The ambient air temperature is not higher than +40℃, not less than -5℃, and the average temperature within 24 hours is not higher than +35℃.

● Atmospheric conditions, clean air, relative humidity is not more than 50% at the highest temperature of +40℃, higher relative humidity is allowed at lower temperatures. For example, 90% at +20C, but temperature changes should be taken into account and moderate condensation may occasionally occur.

● The altitude does not exceed 2000m.

● The device is suitable for transport and storage at temperatures ranging from -25°C to +55 °C and up to +70 °C in a short time. The device should not suffer any irreversible damage at these extreme temperatures and should work normally under normal conditions.

● If the above conditions cannot be met, it shall be settled by the user and the manufacturer through negotiation.
