Environmental
The SDM-2020D must not be operated in an environment where the unit is exposed to
extremes of temperature outside the ambient range 0 to 50°C (32 to 122°F), precipitation,
condensation, or humid atmospheres above 95% RH, altitudes (un-pressurized) greater
than 2000 meters, excessive dust or vibration, flammable gases, corrosive or explosive
atmospheres.
Operation in vehicles or other transportable installations that are equipped to provide a
