28 Specifications and Standards Compliance
location in which the device is used exceeds the applicable RF compliance level above, it should be
observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the device.
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects, and people.
If you require further information or assistance, please contact Philips Support.
Recommended Separation Distances from Other RF Equipment
The device is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or user of the device can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment and the
device as recommended below, according to the maximum output power of the communications

Radio Frequency Radiation Exposure Information
The radiated output power of the device is far below the FCC radio frequency exposure limits.
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
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).
Leakage currents: If several items of equipment used to monitor a patient are interconnected,
the resulting leakage current may exceed allowable limits.
