Maintenance and Repair
ARNINNG!: Advanced technology, e.g., the use of modern materials and powerful electronics, requires specially adapted
maintenance and repair methods. To avoid a danger of subsequent damage to the apparatus, injuries to persons and/or the
creation of additional safety hazards, all maintenance or repair work on the apparatus should be performed only by a QSC
authorized service station or an authorized QSC International Distributor. QSC is not responsible for any injury, harm or related
damages arising from any failure of the customer, owner or user of the apparatus to facilitate those repairs.
