  2. No possible to efficiently tension by any method.
  3. No possible to shimming.
  4. No possible to feel any true gate.

  6. You can check only one code at the time.

Normal opening procedure:

  2. Rotate key conterclockwise (rise Actuator)
  3. Set the correct code
  4. Rotate the key clockwise (Actuator is going down)
