2- Keep these instructions.
3- Heed all warnings.
4- Follow all instructions.
5- Clean only with a dry cloth.
6- Install in accordance with QSC Audio Product’s instructions and a licensed, professional engineer.
7- Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including ampli-

fiers) that produce heat.

8- Only use attachments/accessories from QSC Audio Products, Inc.
9- Use only with mounts or brackets specified by QSC Audio Products.
10- Refer all servicing to qualified personnel. Servicing is required when the apparatus has been damaged in any 

way.

The exclamation point within an equilateral triangle is intended to alert the user to the presence of 
important operating and maintenance (servicing) instructions in this manual.

WARNING! Before placing, installing, rigging, or suspending any speaker product, inspect all hardware, 
suspension, cabinets, transducers, brackets and associated equipment for damage. Any missing, cor-
roded, 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 equip-
ment. Consult a licensed, professional engineer when any doubt or questions arise regarding a physical 
equipment installation.
