The HELP menu provides quick access to the

• on/off switch.

• primary imaging controls.

• reference manual.

• clinical application specialist.

The frequency control ensures that

• imaging depth is appropriate.

• tissue resolution is adequate.

• the right focal zone is used.

• the image freezes.

When the focal zone indicator is set too deep for the organ being examined

• the echogenicity is too bright.

• the resolution is suboptimal.

• the light output is inadequate.

• the organ needs to be repositioned.
