11) The legibility of the marking must be observed during time in use
but at least during inspection periods of three years. If any harm of
the legibility is found please contact the manufacturer to renew the
marking.
12) Due to potential ignition hazards (e.g. static discharge), the
packaging material and the desiccant bag must not be put in the
hazardous area.
