6 Information about Electromagnetic Radiation
NOTE: U is the alternating mains voltage before the test level is used.
T
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not be applicable in every case. The spread of electromagnetic waves is absorbed and reflected by
buildings, 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 conformance levels in the ISM frequency bands between 150 kHz and 80 MHz and the frequency range of 80 MHz and 2.5 GHz are
intended to reduce the probability that mobile and portable communications equipment will produce disturbances when they are
unintentionally brought near the patient. For this reason, the additional factor of 10/3 is used when calculating the recommended safe
distances within these frequency ranges.
c
The field strength of stationary transmitters such as base stations of mobile telephones and land mobile radio devices, amateur radio
stations, AM and FM, radio and television broadcasters cannot be theoretically predetermined. To determine the electromagnetic
environment of stationary transmitters, a study of the location should be considered. When the measured field strength at the site where the
STATMATIC is used exceeds the above conformance level, the STATMATIC should be monitored to demonstrate proper function. When
unusual performance features are observed, additional measures may be necessary such as realigning or moving the STATMATIC.
d
Within the frequency range of 150 kHz to 80 MHz, the field strength should be less than 3V eff V/m
Recommended safe distance between portable and mobile HF telecommunications equipment and the STATMATIC
The STATMATIC is intended for use in an electromagnetic environment in which HF disturbances are controlled. The customer or the
user of the STATMATIC can help prevent electromagnetic disturbances by maintaining the minimum distance between portable and
mobile HF telecommunications devices (transmitters) and the STATMATIC depending on the output of the communication device as
indicated below.

For transmitters whose maximum rated power is not in the above table, the recommended safe distance d in meters (m) can be calculated
using the equation for the respective gap, where P is the maximum rated power of the transmitter in Watts (W) according to the
manufacturer's information.
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not be applicable in every case. The spread of electromagnetic waves is absorbed and reflected by
