The TEE transducers are classified as Type BF isolated patient-applied parts, as described in IEC
60601-1. There are no exposed conductive surfaces distal to the transducer handle. To ensure
safe operation of this transducer, read the cautions and warnings in the “Safety” section,
especially those that address electrosurgical units, pacemakers, and defibrillators.
The following table summarizes patient safety problems, describes how to prevent them, and
lists the sections in this manual where details are provided.
WARNING
If you encounter an irregularity not listed in the following table, do not use the transducer.
Potentially serious consequences could result. Contact your Philips representative.
