Appendix – Aanbevolen afstand tot RF-apparatuur
Recommended separation distances between portable and mobile RF communications
equipment and the equipment
The Emfit Nocturnal Epileptic 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 Nocturnal Epileptic 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:
•
At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
These guidelines may not apply in all situations. Electromagnetic propagation is
•
affected by absorption and reflection from structures, objects and people.
