shaft of the transducer handle, and the white line on the articulation control
is aligned with the center of the proximal end of the transducer handle.
• Bite guards are mandatory; protective transducer covers are recommended
for TEE transducers, but in China and Japan, the covers are mandatory. See
"Electrical Safety and TEE Transducers" on page 246.
CAUTION
To avoid damaging gastroscope cables, be sure that the distal tip of the transducer
is in the neutral (straight) position when inserting a transducer into, or removing
it from, the transducer cover.
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.
