Menu key
Pressing the menu key once will display the current menu function, whilst
pressing it more times or holding it down will scroll through the available
menus.
Enter key
The enter key is used for storing selected values into non-volatile
memory. If the enter key is not pressed the selected value will be stored in
Flash memory, which means that they will not be remembered by the
machine next time it is powered.
Up/Down key
The up and down keys are used for selecting values according to the
accessed menu. The keys can be operated with single keystrokes or held
down to scroll through the available options.
After approximately 15 seconds since the last keystroke, the display will
leave the edit mode and revert to displaying the current status
information. If the values have not been stored by pressing the enter key
these will only apply until the machine is shut down.
When not in edit mode, the display will show information appropriate to
the current operating mode. The display will alternate between two
messages, e.g. 'Fog' and '16'. The first message shows the menu, and
the second one shows the value chosen for this menu. Some messages
are compounded together to form one message, e.g. 'FLu/Lo' indicating
low fluid in the fluid container. For more information about the messages
to expect, see the section 'DISPLAY MESSAGES' for a complete list of
the messages and the circumstances under which they are displayed.
The menus available on each display and the functions they perform are
as follows:
