WARNING Do not connect any devices that are not supported as part of a system.
System Example
This illustration shows a system where both the medical electrical equipment and the non-medical
electrical equipment is situated at the patient’s bedside.
WARNING Any non-medical device placed and operated in the patient’s vicinity (within a distance of 1.5m from the
patient’s bed) must be powered via an approved separation device (for example, an isolation transformer).
If the personal computer (or any other non-medical electrical device) is situated outside the medically used
room, you must take measures to reduce leakage currents, such as providing an additional protective earth,
a non-conducting enclosure, or a separation device.
We highly recommend using a separation device whenever you connect non-medical electrical equipment.
Regular Preventive Maintenance
The care and cleaning requirements that apply to the Avalon CTS and the monitoring accessories are
described in the
Instructions for Use . This section details the periodic maintenance recommended for the
base station, transducers and accessories.
Mechanical Inspection
All rear panel connections must be tight. Check all exterior housings for cracks and damage. Check the
condition of all external cables, especially for splits or cracks and signs of twisting. If serious damage is
evident, the cable should be replaced immediately. Check that all mountings are correctly installed and
secure. Refer to the instructions that accompany the relevant mounting solution. Check that the protective
earth cable is properly and securely connected.
