4 Transducer Surface Temperature Limits
For probes intended for internal applications, e.g. the endocavitary or transesophageal
probes, the surface temperature of the probe may change by adjusting system parameters.
The maximum surface temperature of the endocavitary probes is 43°C. To protect the
patient against the harm of excessive temperature, the probe stops working automatically
when its temperature reaches the limit. The surface temperature of the probe is displayed
on the right side of the screen.

5 Imaging Functions that Change Acoustic Output
The qualified operator may use the system controls to limit the ultrasound output and to
adjust the quality of the images. The operator should observe the acoustic output display
for possible effects.
There are three categories of system controls relative to output. They are controls that
have direct effect on the output, controls that indirectly control output and controls that are
receiver controls.
