Display layout
1. The current range, operating frequency, power and gain settings are displayed at the top left hand
corner of the screen.
2. The remote tally counter results are always displayed at the top of the screen; these are counted
from the remote tally box, connected to the front panel at ‘TALLy’ (See Appendix E, connector F).
3. The grey bar below this contains 32 of the 256 shades of grey. This helps with the adjustment of
brightness and contrast and gives a comparison of grey intensity for the ultrasound picture.
4. The real time ultrasound sector can be displayed either as an inverted image or non inverted
image. As the range is altered, the speed of the probe varies to provide the best quality image.
The smaller the range, the faster the probe rotates.
5. The current function of the ‘soft’ keys is displayed along the bottom of the screen.
