To set the criterion level to 80 dB and the exchange rate to 3 dB, set the next 4 positions down.
For a high threshold of 80 and a low threshold of 70 set the first 4 positions of the right switch to down, up, up, and up.
To identify this unit as unit 0 set the next three switches down. (If the unit number is set to zero the code will not show the leading zero.)
All the switch positions in a column must be set to get the correct settings. Notice, as an example, the 115 dB upper limit switch could be up or down depending on the range setting. Also the threshold settings are encoded.
