Electromagnetic compatibility
Note:
The deviating test values derived
from IEC 60601-2-24 are labelled in the
table. However, these test values allow one
outage with an alarm while the test values
according to DIN EN 60601-1-2 do not
allow any outages.
The compliance levels for ISM frequency
bands between 150 kHz and 80 MHz and
in the 80 MHz to 2.5 GHz frequency range
are designed to minimise the likelihood of
mobile/portable communications equipment
causing interference if accidentally brought
into the patient area. For this reason the
additional factor 10/3 is used when calcu-
lating the recommended safe distances in
these frequency ranges.
Field strengths emitted from stationary
transmitters (such as base stations for
cordless telephones and land mobile radio
devices, amateur radio stations, or AM
and FM radio and television broadcasts)
theoretically cannot be predicted exactly.
Consider conducting a study of the site to
determine electromagnetic environmental
conditions as regards stationary transmit-
ters. If the measured field strength in the
area the Infusomat® compact
plus
P is being
used in exceeds compliance levels, moni-
tor the Infusomat® compact
plus
P to ensure
that it is functioning properly. If abnormal
performance is observed, additional meas-
ures may be necessary, e.g., changing the
device’s location or facing it in a different
direction.
