The buttons
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 col-

change and push the middle buttons until value for the parameter
is shown. When you have changed the value, save the new value
