The TEE probes include sensors to monitor the temperature of the tip during use.  While 
imaging the following on-screen indicator is shown: 
 
 
The angle of rotation shows the scan plane rotation while the temperature indicator shows the 
temperature at the transducer face.  This indicator can optionally be turned off if the 
temperature is below 40.5ºC.  Above that temperature the indicator will always be displayed.  In 
addition: 
•
 
If the temperature reaches 41.5ºC the system will automatically freeze and display a warning 
message. This warning message can be dismissed and imaging can continue.  While operating 
at this temperature is safe, close monitoring of the temperature is recommended.  The 
temperature indicator will show in yellow to indicate this. 
•
 
If the temperature reaches 42.7ºC the system will automatically freeze imaging.  The 
transducer  must be disconnected and allowed to cool off before additional imaging is 
supported.
