All adjustable value, parameter or option item
displays are grouped into ‘menu mode’ lists.
Items are assigned to a list according to type

page number (or menu number); All adjustable
parameters and options are assigned to menu
mode pages ‘P01’ or higher.
Normal Operational Display (Menu Page P00):
At controller initialisation, all LED indicators
are switched on for several seconds before

at any one time and can be viewed by
