Advisable separation distances between mobile and portable RF communications equipment and the Eazy PRO
The Eazy PRO is intended to be used in the electromagnetic environment specified below. The customer or user of the defibrillator
should ensure that it is used in such an environment.
Immunity Test
Test Level of ABNT NBR
IEC 60601
Compliance Level
Electromagnetic Environment – Directive
Portable and mobile RF communications
equipment should not be used near any part
of the Eazy PRO, including cables, with a
separation distance less than the one advised,
calculated using the equation applicable to the
frequency of the transmitter.

Where “P” is the maximum output power of
the transmitter in watts (W), according to the
transmitter manufacturer, and “d” is the advisable
separation distance in meters (m)

d
.
Interference can occur around
equipment marked with
the following symbol:
NOTE 1: At 80MHz and 800MHz, the highest frequency range is applied.
NOTE 2: These directives may not be applicable in all situations. Electromagnetic transmission is affected by the absorption and
reflection of structures, objects and people
a
ISM bands (industrial, medical and scientific) between 150kHz and 80MHz are 6,765MHz to 6.795MHz; 13.553Mhz to 13.567MHz;
26.957MHz to 27.283MHz; and 40.66MHz to 40.70MHz.
b
The compliance levels in the ISM frequency bands between 150kHz and 80MHz and in the frequency range between 80MHz and
2.5GHz are intended to reduce the likelihood of mobile and portable communications equipment causing interference if inadvertently
brought into the patient areas. Therefore, an additional factor of 10/3 is used in calculating the advisable separation distance for
transmitters in these frequency ranges.
c
Field strengths established by fixed transmitters, such as base stations for radio, telephones (cell phone/wireless) mobile land
radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with any accuracy. In order to
evaluate the electromagnetic environment due to fixed RF transmitters, it is advisable to consider an electromagnetic site survey. If the
measured field strength in the site where the Eazy PRO is used exceeds the level of RF compliance used above, the Eazy PRO should
be observed to check if operation is normal. If abnormal performance is observed, additional procedures may be required, such as
reorienting or repositioning the Eazy PRO.
d
Over the frequency range 150kHz to 80MHz, the field intensity should be less than [V1]V/m.
