The Greyed Out parameters not selectable with the current version of code.
The table below is splli into the three ‘Levels’ corresponding to BASIC, ADVANCED and SERVICE levels
of operation.
The BASIC functions are also included in the ADVANCED level, this is to allow all functions of the unit
to be configured by a competent operator; the normal operational functions can then be changed at
the BASIC level.
The SERVICE functions are intended for diagnostics and servicing by a technician / engineer.
