WARNING
For any other irregularity not listed in the following table, do not use the transducer.
Potentially serious consequences could result. Contact your Philips representative.
Preventing TEE Transducer Equipment Problems
Problem Effect on Equipment Prevention See
Current leakage Serious electrical hazards Check the transducer for cuts, frayed
insulation, kinks, or other
abnormalities.
“Checking the TEE
Transducer” on page
223
Biting transducer Mechanical and electrical
hazards
Cover the patient's teeth with a bite
guard (mandatory). Cover the distal tip
and flexible shaft with a transducer
cover (recommended, but in China and
Japan, mandatory).
“Bite Guards” on page

Forcing deflection
controls
Steering mechanism broken Operate the deflection controls gently. “X7-2t Deflection
Controls” on page 211
and “S7-3t TEE
Controls” on page 218
Incorrect storage Possible damage to highly
sensitive elements, cuts in
flexible shaft
Suspend the transducer from a wall-
mounted rack and the distal tip with a
tip protector when not in use.

Internal exposure
to liquids
Severe transducer damage
that affects the image
quality, the steering
mechanism, and electrical
safety
Never sterilize the transducer by using
bleach, steam, heat, or ethylene oxide
(EtO). Never immerse the steering
mechanism in any disinfectant or liquid.
