Chapter 1 - Safety
Patient Safety
The Telemetry System should only be used by, or under the direct supervision of, a
licensed physician or other health care parctitioner who is trained in the use of fetal
heart rate monitors and in the interpretation of fetal heart rate traces. US federal law
restricts this device to sale by, or on the order of, a physician.
The Telemetry Receiver is a Protection Class 1, Type B instrument. It is
designed to fulfill safety requirements according to IEC 60601-1, UL 544 and CSA-
C22.2 No.601.1-M90.
The telemetry transmitter is a battery operated device, applied parts (patient
connectors) are Type CF
.
Environment
Use the system in an environment which is reasonably free from vibration, dust,
corrosive or explosive gases, extremes of temperature and humidity. It operates within
specifications at ambient temperatures between 0 and +45°C. Ambient temperatures
that exceed these limits can affect the accuracy of the system, the transmitter radio
frequency transmission, and can damage the components and circuits.
The system (not including transducers
1
) can be stored at ambient temperatures
between -40°C and +75°C.
The blue Toco and Ultrasound transducers are water-tight to a depth of 50 cm (19.7
inches).
Warning
Do not use brown transducers to monitor patients under water. Ultrasound and
Toco transducers that are colored blue are watertight and comply with IEC 529
(IP68).
You can immerse the BLUE Ultrasound and Toco tranducers in water ONLY
when connected to the telemetry transmitter. NEVER connect blue transducers
directly to the fetal monitor when they are immersed in water, or likely to come
in contact with water.
NEVER immerse the telemetry transmitter in water or other liquids such as
cleaning solutions.
