DIP switch sections 3 and 4 determine how peak levels are displayed
(display mode) and select either the PPM mode or an auto-reset VU peak
mode (not the PPM value). The PPM mode exhibits an attack time of 10
milliseconds and a decay time of 2 seconds from 0 to -20 dB. The VU
mode exhibits a 300 millisecond rise to 99% of full indication and a decay
of 300 milliseconds. The factory setting is VU mode. See the diagram
below for settings.
