Operation Procedures”)
Focus number selection
Press this key to lighten up the “ focus number” on the screen right top, press again to change the focus numbers.
There are two focus at most. Press this key to switch between one focus to two.

or
to change the scanning
angles. The angel range is 50%-100%.
Tips: When linear probe or rectal linear probe is used, this function can not be used.
the angle can improve the image’s frame rate and increase the cine loop frames
