the intensity of tone is increased by 5 dB without interrupting the tone, but the timing at the top of the

Once this measurement has been finished the data can be documented as a comment to the session by the
‘Transfer result to comments’ on the left of the screen. Alternatively it can be saved via the disk or door icon
in the top left for review later on.
