12. Care and Maintenance
1.
Warning
Damage and wear to the speakers and accessories may considerably affect your personal
safety.
The K&F SCENA 12 system can exhibit signs of wear over the years, for example, from
mechanical strain, transport damage, corrosion, or improper handling.
Be sure to always perform a visual inspection of the speaker and all accessories before
and after installation. In stationary installations, check the speaker and accessories for
signs of wear at regular intervals.
When performing those checks, particularly look for deformations, cracks, dents, damage
to threads, and corrosion.
If as a result of these checks any uncertainty should arise with regard to safety or defects
are found, don’t use the speaker any longer. If the product is found to be faulty, return
to KLING & FREITAG GmbH for inspection and repair as necessary.
Inspection regulations may vary depending on application and country of use. Observe
all applicable regulations; when in doubt, contact the local authorities.
Many countries require regular inspection of mounting components and accessories. An
additional annual inspection is typically required to be performed by a technical expert.
Moreover, a legally certified or official authority must perform a detailed inspection
every four years.
Therefore, be sure to maintain an inspection log. Enter the values determined for each
speaker and accessory during the periodic checks into this log. This way, relevant data
are always at hand in case of inspection. The log should also document maintenance
measures and inspection intervals and contain parts lists.
2. Operate the mode switch on the connector panel of the speaker at least once every six
months to ensure its function.
3. The polyurea coating utilized by Kling & Freitag is shock-resistant and highly resilient.
We recommend using protective coverings or transport cases to help avoid damaging the
paint in case of continuous mobile use, etc.
4. To have the acoustic foam replaced, send the grille including the foam layer to
Kling & Freitag GmbH. We will then replace the foam layer with a new one at a fixed
charge and return your grille.
