• Whenever the TEE transducer is not being used during a procedure, ensure
that it is in freewheeling mode and unplugged from the system.
• To prevent tissue damage, Philips recommends that the tip of the TEE
transducer be straightened and both detent brakes released before you
reposition the transducer or withdraw the transducer from the patient. In
the neutral position, the tip is straight when the indicators on the control
wheels are aligned and point toward the center of the array rotation button.
• 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 233.
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.
