a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM
and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed
RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the patient lift is used

frequency of the transmitter.
Recommended separation distance:

transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
