The Trumpet is designed for use in an electromagnetic environment as specified
below. The user of the Trumpet must ensure that the instrument is operated in
ambient conditions as specified.
Immunity tests
Test level to EN
60601
Level of
Compliance
Electromagnetic
environment -
guidelines
Electrostatic
discharges (ESD)
IEC 61000-4-2
± 6kV contact
± 8 kV air
± 6kV contact
± 8 kV air
The floor must be wood,
concrete or ceramic tile. If
floors are covered with
materials that present
synthetic coatings, relative
humidity must be at least
30%.
Electrical fast
transients / bursts
IEC 61000-4-4
± 2 kV for
electrical power
supply lines
± 1 kV for
input/output lines
± 2 kV for
electrical power
supply lines
± 1 kV for
input/output lines
The quality of the
electricity supply from the
grid must be the same as
for typical commercial or
hospital premises.
Overcurrent
IEC 61000-4-5
± 1 kV from
line(s) to line(s)
± 2 kV from
line(s) to earth
± 1 kV from
line(s) to line(s)
± 2 kV from
line(s) to earth
The quality of the
electricity supply from the
grid must be the same as
for typical commercial or
hospital premises.

The quality of the
electricity supply from the
grid must be the same as
for typical commercial or
hospital premises. If the
user of the Trumpet needs
to rely on uninterrupted
operation of the unit even
in the absence of mains
power, the instrument must
be connected either to a
UPS or to a battery.
Magnetic field at
power frequency
(50/60 Hz)
IEC 61000-4-8
3 A/m
3 A/m
Power frequency magnetic
fields must correspond to
the levels characteristic of
sites located typically in
standard commercial or
hospital premises.
Note: U
T
is the a.c. supply voltage prior to application of the test level.
