# Operating, transportation and storage conditions
Operate your devices under the following climatic conditions:
relative humidity: 45 ~ 80%;
atmospheric pressure: 84.0 - 106.7 kPa (630 - 800 mm Hg).
The ambient air temperature should not exceed 40°C. In the case of elevated room temperatures, it may be necessary to arrange forced air circulation, such as installing a ceiling fan.
The operating temperature for the TrueConf Group Silent version can reach up to 60°C on the surface of the case in the area of the radiator fins, which is normal. Operating conditions (see section 2) should ensure that the case temperature does not exceed 60°C.
Packaged endpoints can be transported by all transport modes according to the category 5 conditions of GOST 15150-69, except for unpressurized aircraft compartments and open decks of ships and vessels.
Terminals are transported by rail in containers in accordance with the requirements of GOST 18477-79.
When transported in sub-zero temperatures, terminals must be kept for at least 24 hours in normal climatic conditions before unpacking.
At supplier and consumer’s warehouses, video conferencing endpoints must be kept under storage conditions 1 according to GOST 15150-69 with no acidic, alkaline and other aggressive impurities in the air.
According to the manufacturer, the device’s service life is 5 years if the consumer sticks to the rules and conditions of operation, transportation and storage.
Given that the device is a high-quality and reliable product, the actual service life may exceed the labeled one.
