At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Revision A
The table below provides the recommended separation distances (in
meters) between portable and mobile RF communication equipment
and the Corometrics Intrapartum Monitor, Model 173. The
Corometrics Intrapartum Monitor, Model 173, is intended for use in
the electromagnetic environment on which radiated RF disturbances
are controlled. The customer or the user of the Corometrics
Intrapartum Monitor, Model 173, can help prevent electromagnetic
interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the
Corometrics Intrapartum Monitor, Model 173, 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.
