The REHAB SERIES device is intended for operation in an electromagnetic environment
where RF disturbances are monitored. The customer or user of the REHAB SERIES device can
help prevent electromagnetic interference by maintaining a minimum distance between por-
table and mobile RF telecommunications 4- series (transmitters) and the REHAB SERIES
device – according to the output power of the communications device, as indicated below.
Recommended separation distances between portable and mobile RF telecommunications
4- series and the REHAB SERIES device
Theoretically, it is not possible to exactly predict the field strengths of fixed transmitters such
as base stations for radio telephones and land mobile radios, amateur radio stations, AM
and FM radio and TV broadcasting. To determine the electromagnetic environment in rela-
tion to the fixed transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location where the REHAB SERIES device is to be used exceeds
the above compliance levels, the REHAB SERIES device should be monitored in order to
ensure that it is functioning as intended. If unusual features are noticed, additional measures
may be necessary such as re-orienting or relocating the REHAB SERIES device.
Above the frequency range from 150 kHz to 80 MHz the field strength should be less than
3 V/m.
NOTE 1 At 80 MHz and 800 MHz the higher frequency range is applicable.
NOTE 2 These guidelines may not be applicable in all cases. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
