Appendix C: Electronic Compatibility (EMC)
The NXT needs special precautions regarding EMC (Electro Magnetic Compatibility) and
needs to be installed and put into service according to the EMC information provided in this
manual.
For EM compliance, it is important to only use catheters and accessories as supplied or
recommended by LABORIE. Contact LABORIE for approved catheters.
Recommendations for actions to assure that the NXT remains safe regarding EM
disturbances:
The equipment should be visually inspected regularly for damaged cables and
connectors. Damaged cables should be replaced.
If the NXT system is used in a location near (e.g. less than 1.5 km from) AM, FM
or TV broadcast antennas, it may be necessary to take preventive actions for
reducing the EM interfering level (for instance by shielding the investigation
room).
The NXT system contains Bluetooth wireless modules which intentionally receive and
transmit RF electromagnetic energy in the 2.4 GHz ISM frequency band.
Guidance and Manufacturer’s Declaration—Electromagnetic Emissions
The NXT measurement system is intended for use in the electromagnetic environment
specified below. The customer or the user of the NXT measurement system should assure
that it is used in such an environment.
When the NXT system is exposed to electromagnetic (EM) disturbances, the system may
show abnormal behavior. For instance, the measured traces may become obscured, the
software may crash or, in case of very high-level transient voltage events like for instance
ESD, parts of the system may even become defective.

Electromagnetic Environment Guidance
RF emissions
CISPR 11
Group 1
The NXT uses RF energy only for its
internal function. Therefore, its RF
emissions are very low and are not
likely to cause any interference in
nearby electronic equipment.
RF emissions
CISPR 11
Class A
The EMISSIONS characteristics of the
NXT make it suitable for use in
industrial areas and hospitals (CISPR 11
class A).
If it is used in a residential environment
(for which CISPR 11 class B is normally
required), this equipment might not
offer adequate protection to radio-
frequency communication services. The
user might need to take mitigation
measures, such as relocating or re-
orienting the equipment.
