NOTE 1 At 80 MHz and 800 MHz the higher frequency
range applies.
NOTE 2 These guidelines may not be applicable in all ca-
ses. Electromagnetic propagation is influenced by
absorptions and reflections by buildings, objects
and people.
a The field strength of stationary radio transmitters, such as
base stations for wireless telephones and land mobile ra-
dios, amateur radio stations, AM and FM radios and TV
stations, cannot be predicted theoretically with accuracy.
To determine the electromagnetic environment with regard
to the stationary transmitter, an electromagnetic site survey
should be considered. If the measured field strength
exEECds the above compliance level in the location in
which the blood pressure monitor SBM 68 is being used,
the blood pressure monitor SBM 68 should be observed
to verify normal operation. If you observe unusual perfor-
mance characteristics, additional measures may be requi-
red e.g. changing orientation or choosing another location
for the blood pressure monitor SBM 68.
b Over the frequency range of 150 kHz to 80 MHz, the
field strength should be lower than 3 V / m.
