The table below provides the recommended separation distances (in meters)
between portable and mobile RF communications equipment and the 250 Series
Maternal/Fetal Monitor.
The 250 Series Maternal/Fetal Monitor is intended for use in the electromagnetic
environment on which radiated RF disturbances are controlled. The customer or the
user of the 250 Series Maternal/Fetal Monitor can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the 250 Series Maternal/Fetal
Monitor as recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not listed above, the
recommended separation distance [d] in meters (m) can be estimated using the
equitation applicable to the frequency of the transmitter, where P is the maximum
output power rating of the transmitter in watts (W) according to the transmitter
manufacturer.
NOTE:
These guidelines may not apply in all instances. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
