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 models X-Cure are used exceeds the
applicable RF compliance level above, the model X-Cure should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the models X-Cure.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
Recommended separation distances between
portable and mobile RF communications equipment and the models X-Cure
The models X-Cure are intended for use in electromagnetic environment in which
radiated RF disturbances is controlled. The customer or the user of the models X-Cure
can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the
models X-Cure are 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 equation applicable to
the frequency of the transmitter, where P is the maximum output power rating of the
transmitter in watts (W) accordable to the transmitter manufacturer.
NOTE I 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.
