TECHNICAL DATA
9.1.3.2 Points of Contact with the Patient
COMPACT PIeZO P2K is designed to operate in the electromagnetic environment specified
below.
The purchaser or user of COMPACT PIEZO P2K should ensure that it is used in such an
environment.

synthetic material, the relative
humidity should be at least

should not be used near any
part of the product, including
cables, except when they
respect the recommended
distances, calculated from the
equation applicable at the
frequency of the transmitter.
a) The following applies:
• All connection cables with the patient must be tested,
either individually or grouped together.
• The connection cables with the patient must be tested
using a current clamp unless the current clamp is
not suitable. If a current clamp is not suitable, an EM
clamp must be used.
• In any case, no intentional decoupling device should
be used between the injection site and POINT OF
CONNECTION TO THE PATIENT.
• The tests can be performed with other modulation
frequencies identified by the RISK MANAGeMeNT
PROCESS.
• The tubes that are intentionally filled with conductive
liquids and intended to be placed in contact with the
PATIENT must be considered connection cables with
the patient.
• If an ISM or amateur radio band is not present among
the frequency samples, as appropriate, an additional
test frequency has to be used in the ISM band or in
the amateur radio band. This applies to each ISM and
amateur radio band within the specified frequency
range.
• The ISM bands (industrial, scientific and medical)
between 0.15 MHz 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. The
amateur radio bands between 0.15 MHz and 80 MHz
are 1.8 MHz to 2.0 MHz, 3.5 MHz to 4.0 MHz, 5.3 MHz
to 5.4 MHz, 7 MHz to 7.3 MHz, 10.1 MHz to 10.15
MHz, 14 MHz to 14.2 MHz, 18.07 MHz to 18.17 MHz,
21.0 MHz to 21.4 MHz, 24.89 MHz to 24.99 MHz, 28.0
MHz to 29.7 MHz and 50.0 MHz to 54.0 MHz.
b) R.M.S., applied before modulation.
c) The discharges must be applied without connection
to an artificial hand and without connection to the
PATIENT simulation. The PATIENT simulation can be
connected after the test, if necessary, to verify BASIC
SAFeTY and eSSeNTIAl PeRFORMANCe.
