Along with the buttons and the display, the LPU-2127 includes a detected signal strength indicator. On the
leftside of the display are bars to indicate the strength of the signal returning to the sensor (See Figure 3.2).
Three bars indicates excellent signal strength; two bars indicates good signal strength; one bar indicates fair
signal strength; no bars indicates loss of echo (no signal).
