Electrical Hazards
WARNING
Electrical shock hazard: Do not open the monitor housing. Refer all servicing to qualified service
personnel.
• Always use the supplied power cord with the earthed mains plug to connect to an earthed AC
mains socket. Never adapt the mains plug from the fetal monitor to fit an unearthed AC mains
socket.
• Do not use AC mains extension cords or multiple portable socket-outlets.
• FM20/FM30 only: The protective earth conductor is required for EMC purposes. It has no
protective function against electric shock. Double and/or reinforced insulation protects this
device against electric shock.
• Do not connect any devices that are not supported as part of a system.
• Any non-medical device placed and operated in the patient’s vicinity must be powered with an
approved isolation transformer that ensures mechanical fixing of the power cords, and covering of
any unused power outlets.
• The fetal/maternal monitor is NOT intended for use during defibrillation, electro-surgery, or
MRI. Remove all transducers, sensors, and accessories before performing electro-surgery,
defibrillation, or MRI, otherwise harm to the patient or the user can result.
• Do not touch the charging contacts for the cableless transducers at the Avalon CL base station
while you are touching the patient.
Leakage currents: If several items of equipment used to monitor a patient are interconnected, the
resulting leakage current may exceed allowable limits.
Radio Frequency Interference
WARNING
• Short range radio connections are subject to interruption due to interference from other radio
sources in the vicinity, including microwaves, bluetooth devices, WLAN devices (802.11b,g,n), and
cordless phones. Depending on the strength and duration of the interference, the interruption may
occur for an extended period. A loss of connection, due to moving out-of-range, interference, or
for other reasons, is indicated with a
No Host Monitoring INOP (here the host is the fetal monitor)
on the IntelliVue CL NBP or CL SpO
2
Pods, or a No Host Monitoring, or cl NBP Disconnect, or cl
SpO₂ Disconnect
INOP at the fetal monitor. Correct channel configuration is important, refer to
the Service Guides and the Configuration Guide for details.
• To avoid magnetic interference affecting the mode of the pacemaker, ensure that the
Avalon CL base station does not come into close contact with implanted pacemakers.
• This equipment generates, uses, and radiates radio-frequency energy, and if it is not installed and
used in accordance with its accompanying documentation, may cause interference to radio
communications. Operation of this equipment in a residential area may cause interference, in
which case the users must take whatever measures may be required to correct the interference.
• Do not use cordless/mobile phones or any other portable RF communication system within the
patient vicinity, or within a 1.0 m radius of any part of the fetal monitoring system.
