Preface
Environmental
The CDM-600L 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-
pressurised) greater than 2000 metres, excessive dust or vibration, flammable gases,
corrosive or explosive atmospheres.
