General rules for buttons and symbols on the display
The symbols shown as an example are not present on all crane types.
The following rules apply in all menus:
– A menu can only be opened if the relevant symbol has been selected with
the jog dial ( 1 ) or direction buttons ( 2 ).
– A selected menu is marked in colour and can be opened.
– Symbols can be shown in different colours. The colour of the symbol
indicates the current switching state of the relevant power unit.
– In these operating instructions, we always refer to colours in terms of
“The symbol is red ”, for instance.
regardless of whether the background ( 1 ) of a symbol is red or whether
only parts ( 2 ) of a symbol are red . This applies to all symbols and all
colours.
If the instruction given in this section is to “Press the button once...”, for
instance, this always refers to the button (
1 ) or ( 2 ). This is the case if a menu
is opened or a function is to be carried out.
1 Grey: e.g. main hoist – switched off
