13. Care and Maintenance
13.1
For the owner and user, it is mandatory to be aware of the safety relevance of speakers that
can be flown.
Note that the mains cable is supplied with either a connector appropriate for the place of
delivery (see item number) or with open terminals (on the mains side).
Warning
The PASSIO system can exhibit signs of wear over the years, for example, from mechanical
strain, transport damage, corrosion, or improper handling. Remember that flying speakers
always impose a high safety risk.
Generally, perform a visual inspection of your speaker every time you suspend it or take it
down. PASSIOIn fixed installations, check the speaker for signs of wear at regular intervals.
When performing those checks, particularly look for deformations, cracks, dents, damage
to threads, and corrosion. Also check slings and lifts (e.g. shackles, chains, and steel ropes)
carefully for wear and deformation.
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. PASSIO
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.
