The K3 is suitable for use in all establishments other than
domestic, and may be caused in domestic
establishments
and those directly connected to the public low-voltage
power supply network that supplies buildings used for
domestic purposes, provided the following warning is
needed:
Warning: This equipment/system is intended for use by
healthcare professionals only. This equipment/ system
may cause radio interference or may disrupt the
operation of nearby equipment. It may be necessary to
take mitigation measures, such as re-orienting or
relocating the K3 or shielding the location.

d be observed to verify normal operation. If abnormal performance is observed, additional measure
s may be necessary, such as re- orienting or relocating the K3.
