PACE 203H – Instructions for Use

Recommended Safety Distances to Portable and Mobile RF
Equipment
Standard: IEC 60601-1-2: Table 3
PACE 203H is intended for use in an electromagnetic environment, in which the RF
interference 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 environment.

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].
Note 1:
At 80 MHz and 800 MHz, the safety distance for the higher frequency range applies.
Note 2: 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.
Note 3: 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).
Note 4: 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.
