Important Safety Precautions & Explanation of Symbols

Install in accordance with QSC Audio Product's instructions and under the supervision of a licensed Professional Engineer.

WARNING! 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.

•Before placing, installing, rigging, or suspending any speaker product, inspect all hardware, suspension, 

enclosures, transducers, brackets and associated equipment for damage. Any missing, corroded, deformed, or 

non-load rated component could significantly reduce the strength of the installation or placement. Any such 

condition severely reduces the safety of the installation and should be immediately corrected. Use only hard-

ware 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 regarding physical equipment installation. All local, state and 

national regulations regarding the safety and operation of equipment are understood and adhered to.

•Use only load rated hardware to attach to the eyebolts or pull-back bar when suspending these products.

•Do not suspend these products from any structural element on the enclosure other than the load rated M10 

suspension points.

•Do not suspend the HPR152i or HPR153i horizontally under any circumstances using this or any other hard-

ware.
