Testing the
Immunity to

according to
IEC 60601
Compliance
Level
Guidelines for the
Electromagnetic Environment
P
is the maximum rated power of
the transmitter in watts (W)
according to the information of the
transmitter manufacturer and
d
is
the recommended safety distance in
meters (m).
b
Field strength of stationary RF
transmitters must be determined
site
c
and must be be less than the
compliance level at all frequencies
d
.
Interference may occur in the
vicinity of devices marked with the
following symbol:
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines do not necessarily apply in all situations. The propagation of
electromagnetic waves is influenced by absorption and reflection from structures,
objects and humans.
a The ISM bands (for ndustrial, 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 level in the ISM frequency bands between 150 kHz and 80 MHz and in the
frequency range 80 MHz to 2.5 GHz is intended to reduce the likelihood that mobile/portable
communications devices cause interference if they are unintentionally brought into patient
areas. For this reason greater safety distance is recommended separation distance in these
frequency ranges (factor 12 instead of 0.35).
c The field strengths of staionary transmitters, such as base stations for mobile phones and land
mobile radios, amateur radio stations and radio broadcast and TV broadcasta cannot be
predicted with accuracy. To assess the electromagnetic environment by fixed RF transmitters,
a study of the location should be considered. If the measured field strength exceeds the HF
compliance level at the location where PACE 203H is used, PACE 203H must be observed to
ensure correct functioning. Additional measures may be necessary, such as reorienting or
relocating PACE 203H.
d In the frequency range 150 kHz to 80 MHz the field strengths should be less than 10 V/m.
