8.2.2 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 indi-
cates the current switching state of the relevant power unit.
– In these operating instructions, we always refer to colours in terms of e.g.
“The symbol is red”.
regardless of whether the background (2) of a symbol is red or only parts
(1) 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.
1Red: e.g. main hoist – off
2Green: e.g. auxiliary hoist – on
