freely transferable during the term of the warranty period. The warranty on QSC products is NOT VALID if the products have been purchased from an 
unauthorized dealer/online e-tailer, or if the original factory serial number has been removed, defaced, or replaced in any way. Damage to, or loss of any 
software or data residing on the product is not covered. When providing repair or replacement service, QSC will use reasonable efforts to reinstall the 
product’s original software configuration and subsequent update releases, but will not provide any recovery or transfer of software or data contained on 
the serviced unit not originally included in the product.

Customers may have additional rights, which vary from state to state or from country to country. In the event that a provision of this limited warranty is 
void, prohibited or superseded by local laws, the remaining provisions shall remain in effect.

IMPORTANT SAFETY PRECAUTIONS AND EXPLANATION OF SYMBOLS

WARNING! 

Before placing, installing, rigging, or suspending any speaker product, inspect all hardware, suspension, cabinets, transducers, brackets 
and associated equipment for damage. Any missing, corroded, deformed or non-load rated component could significantly reduce 
the strength of the installation, placement, or array. Any such condition severely reduces the safety of the installation and should be 
immediately corrected. Use only hardware which is rated for the loading conditions of the installation and any possible short-term 
unexpected overloading. Never exceed the rating of the hardware or equipment. Consult a licensed, professional engineer when any 
doubt or questions arise regarding a physical equipment installation.
