Maintenance and Repair
WARNING!: 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.
The KC12 does not contain user-serviceable parts. QSC does not recommend using chemicals or solvents to wash loudspeakers.
Instead, use a damp towel with water only, and dry immediately after wiping down. Do not allow water to pool on the connectors,
hardware, or rear user interface.
If exposed to direct sunlight for extended periods of time, the hardware and ABS parts may become discolored or faded. Cover or
shade your KC12 loudspeakers from long-term, direct sunlight whenever possible.
