Environment
Before operation, make sure that the fetal monitor is free from condensation. This can form when
equipment is moved from one building to another, and is exposed to moisture and differences in
temperature.
Use the monitor in an environment which is reasonably free from vibration, dust, corrosive or
explosive gasses, extremes of temperature, humidity, and so forth. It operates within specifications at
ambient temperatures between 0—+45°C (32°F—113°F). Ambient temperatures that exceed these
limits can affect the accuracy of the system, and can damage the components and circuits.
Ambient temperature ranges for storage are -20°C—+60°C (-4°F—140°F) for the monitor, and -
40°C—+60°C (-40°F—140°F) for transducers.
The transducers are watertight to a depth of 1.0 m for at least five hours (rated IP 68).
WARNING
• Leakage currents: If several items of equipment used to monitor a patient are interconnected,
the resulting leakage current may exceed allowable limits.
• ECG electrodes: NEVER allow ECG electrodes to contact other electrical conductive parts,
including earth.

settings unchanged. If the monitor is without power for more than one minute, the behavior depends
