■ MI/TI Display
TI and MI values are displayed in the real time scan on the screen. The operator should observe these index values
during examinations and ensure that exposure time and output values are maintained at the minimum amounts
needed for effective diagnosis.
The MI and TI precision is 0.1.
1�3�4 Probe Surface Temperature Limits
For probes intended for internal applications, e.g. the endocavitary probe 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 lower left side of the screen.

1�3�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.
