Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
The ECG system is intended for use in the electromagnetic environment specified below. It is the responsibility of the customer
or user to ensure that the ECG system is used in such an environment.

Electromagnetic Environment – Guidance
Electrostatic discharge (ESD)
to EN 61000-4-2
± 8 kV contact
± 15 kV air
± 8 kV
± 15 kV
Floors should be wood, concrete or ceramic
tile. If floors are covered with synthetic
material, the relative humidity should be at
least 30 %.
Electrical fast transient/burst to
EN 61000-4-4
± 2 kV for power supply
lines
± 1 kV for input/output
lines
not applicable Mains power quality should be that of a
typical commercial or hospital environment.
Surge to EN 61000-4-5 ± 1 kV differential mode
± 2 kV common mode
not applicable Mains power quality should be that of a
typical commercial or hospital environment.
Voltage dips, short interruptions
and voltage variations on power
supply input lines to EN 61000-4-11
< 5 % UT
(> 95 % dip in UT)
for 0.5 cycles
40 % UT
(60 % dip in UT)
for 5 cycles
70 % UT
(30 % dip in UT)
for 25 cycles
< 5 % UT
(> 95 % dip in UT)
for 5 seconds
not applicable Mains power quality should be that of
a typical commercial or hospital environ-
ment. If the user of the ergoline ECG
telemetry system requires continued opera-
tion during power mains interruptions, it is
recommended that the receiving system be
powered from an uninterruptible power
supply or a battery.
Power frequency (50/60 Hz) mag-
netic field to EN 61000-4-8
30 A/m passed Power frequency magnetic fields should be
at levels characteristic of a typical location
in a typical commercial or hospital envi-
ronment.
The ECG system has no components sus-
ceptible to magnetic fields.
Note: UT is the a.c. mains voltage prior to application of the test level.
