Operation
The buttons on the display
When you want to change a setting, the upper and the lower
buttons will give you a higher or lower value depending on the
button you are pushing. But before you change the value, you
must have access to the menu. You obtain this by pushing the
upper button for a couple of seconds - you will then enter the
column with parameter codes. Find the parameter code you want
to change and push the middle button. When you have changed
the value, save the new value by once more pushing the middle
button.
