PACE 203 H
Testing the Test Level
Immunity to according to
Interference IEC 60601
a The ISM 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 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 stationary transmitters, such as base stations for mobile phones and
land mobile radios, amateur radio stations and radio broadcast and TV broadcasts 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.

PACE 203H is intended for use in an electromagnetic environment, in which the RF inter-
ference is under control. The user of the PACE 203H can help to prevent electromagnetic
interference by maintaining a safety distance to mobile RF communication equipment
(transmitters) – depending on the output power of the communication equipment. as
described below. The user should make sure that PACE 203H is used in such an environ-
ment.

For transmitters whose rated power output is not specified in the table above, the safety can be
calculated using the specified formula for the corresponding frequency. Here P is the rated output
power of the transmitter in watts [W] and d the safety distance in meters [m].
