supplied from an AC power source which uses a
separating transformer (in accordance with IEC
60989) or be provided with an additional protective
earth conductor.
• If a portable multiple socket outlet assembly is used
as an AC power source, it must comply with IEC
60601-1-1. The assembly must not be placed on the
floor. Using more than one portable multiple socket
outlet assembly is not recommended. Using an
extension cord is not recommended.
An operator of the medical electrical system must not
touch non-medical electrical equipment and the patient
simultaneously. This may cause an unsafe electrical
shock to the patient.
Use of portable phones or other radio frequency (RF)
emitting equipment (that exceed electromagnetic
interference levels specified in IEC 60601-1-2) near the
system may cause unexpected or adverse operation.
Monitor operation when RF emitters are in the vicinity.
Use of other electrical equipment on or near this system
may cause interference. Verify normal operation of
equipment in the system before use on patients.
