Recommended separation distances between portable and mobile RF
communications equipment and the Emfit Tonic-Clonic Seizure Monitor.
The Emfit Tonic-Clonic Seizure Monitor is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or the
user of the Emfit epileptic seizure alarm can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the Emfit Tonic-Clonic Seizure Monitor alarm 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 determined 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.
