2. Keep pressing the [M] button until the desired mode is displayed.
3. Keep pressing the [↑] or [↓] button until the desired value is displayed.

Setting/adjusting electrical damping
Difference between setting and adjusting
You can set or adjust the time constant of electrical damping using the buttons. Setting
means that the time constant is automatically set to 0 seconds. Adjusting means that the
time constant is adjusted between 0 and 100 seconds using the steps of 0.1 seconds. This
electrical damping also has an effect on the built-in basic damping of the device.
