7.1.1 Control operation
After long pressing (>1 s) of [MODE], the menu item "CODE" appears. Upon entry of the
password (numerical password, preset to "1234"), you have access to the menu.
When pressing [MODE] repeatedly, you can switch from one menu item to the next.
Depending on the setting selected, non-relevant menu items will be suppressed.
You may browse the menu items in one direction only. It is not possible to switch back to a
previous menu item.
To select the menu item, press [SELECT]. When this item is pressed once, the set value will
be displayed. Another pressing will change the value by +1. By pressing [MODE], the value
will be changed by -1. During setting, the value display is flashing.
Acknowledge the value changed by pressing [SAVE]. As soon as the display stops flashing,
the new value will be saved.
By pressing [MODE], you can switch to the next menu item.
After having browsed all menu items, the display will show "END" and, thereafter, "ON" or
"OFF" again. At the same time, the entered value will be imported and the pump unit started
with a new lubrication cycle.
During the setting process, the unit continues to be ready for operation, i.e. it is capable of
performing a delivery or stirring process during setting.
