Selecting colours for echo strength
The colour scales used by the ME70 are designed to reflect how strong the echoes are. The echo strength is measured in decibels (dB). Each colour in the scale represents an increase (or decrease) in the echo strength. In the basic colour scale with 12 colours, each colour represents a 3 dB step. The  Colour Scale parameters allow you to change the echo strength range (in decibels) that each colour represent.
Prerequisites
