•

The next item under the Master Icon is “Regulation”

. Using scroll keys select regulation, press the Enter key

and six options would be seen (two different pressure bands, in use pressure band and digital pressure band selec

tion) on the regulation screen. These options can be modified per user choice but they should follow the general

compressor pressure range.
