: is the alternating supply voltage prior to application of the test levels.
NOTE 1: The higher frequency range applies for 80 MHz and 800 MHz.
NOTE 2: These guidelines may not be applicable in all cases. The spread of electromagnetic disturbances is influenced by absorption
and reflection of the building, objects and people.
a
The ISM frequency bands (for industrial, scientific and medical applications) between 150 kHz and 80 MHz are 6.765 MHz to 6.795
MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz and 40.66 MHz to 40.70 MHz.
b
The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range between 80 MHz and 2.5
GHz are intended to reduce the probability of mobile/portable communication devices causing any interference whenever they are
inadvertently brought into patient areas. For this reason, the additional factor of 10/3 is sued for the calculation of the recommended
protective distances in these frequency ranges.
c
The field strengths of fixed transmitters, such as base stations for radio telephones and mobile radios, amateur radio stations, AM and
FM radio broadcasts as well as TV broadcasts cannot be predicted in a fully accurate manner. In order to determine the electromagnetic
environment with respect to the stationary transmitter, a study of the location should be considered. When the measured field strengths
at the location at which the STAT
MATIC
smart is used exceeds the compliance level above, the STAT
MATIC
smart should be observed
in order to demonstrate correct functioning. When unusual performance features are observed, additional measures may be necessary,
such as a changed orientation or another location for the STAT
MATIC
smart.
d
Above the frequency range of 150 kHz to 80 MHz, the field strength should be less than 3 Veff V/m.
Recommended protective distances between portable and mobile HF telecommunications devices and the STAT
MATIC
smart.
The STAT
MATIC
smart is designed for operation in an electromagnetic environment in which the HF disturbances are controlled. The
customer or the user of the STAT
MATIC
smart can help avoid electromagnetic disturbances by observing the minimum distance
between portable and mobile HF telecommunications devices (transmitters) and the STAT
MATIC
smart, depending upon the output
power of the communications device, as indicated below.

For transmitters with a maximum rated power not shown in the table above, the recommended protective distance d can be determined
in meters (m) using the equation form the respective column, whereby P is the maximum rated power of the transmitter in watts (W) in
accordance with the information provided by the transmitter manufacturer.
