11.2.3 LED indications using micro-switch at normal running mode of an instrument
When the switch is pressed-down both LED’s will be switched-off for function selection. As long as the switch will be
pressed-down, there will be a change in indication by the 2 LED’s after each 4 seconds. The moment the user
recognizes the indication (LED-pattern) for the function he wants, he must release the switch. Now the wanted
function is triggered.
