# Operating, transportation and storage conditions

  1. 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.
