Important: Remove power before making any internal adjustments.
Using the two slots shown in Figure 1 on page 2, a small flat-blade screwdriver may be used to lift up and remove the black inner cover to
expose the 4-position DIP switch. Use these DIP switches to program the output slope, output mode, loss of echo, and min./max. output
value default.
DIP Switch Function Settings
1 Output slope On = Output value increases with distance
Off* = Output value decreases with distance
