Recommended separation distances between portable RF communications equipment and mobile and fetal
The fetal heartbeat detector is intended for use in an electromagnetic environment in which radiated RF distur-
bances are controlled. The customer or user of the fetal heartbeat detector can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the fetal heartbeat detector, 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 distanced
in meters (m) can be estimated using the equation 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 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
