LEAD STAGE

Used to manually change the lead stage

•The Lead Stage is the first stage brought on when output is required.

•The Lead Stage can be rotated manually or automatically. The automatic rotation is recommended (see pg. 17).

•The current Lead Stage is shown in brackets on the main display.

•Only Stages which are set to Auto Mode can be Lead. Therefore, not all the stages may be available when manually selecting a new Lead Stage.
