WARNING

Warning

. Failure to follow these safety instructions could result in fire, shock or other injury or 

damage to the device or other property.

Safety and handling information

It is important that loudspeaker systems are used in a safe manner.

 

Avoiding Hearing Damage.

 Professional loudspeakers are capable of producing extremely high sound levels 

and should be used carefully. Never stand close to loudspeakers driven at high volume. Set the volume 
to a safe level. Over time you can adapt to a higher volume of sound that may sound normal but can be 
damaging to your hearing. Hearing loss gets worse every time you’re exposed to a sound level of 90 dB or 
over for an extended period of time. If you experience ringing in your ears or muffled speech, stop listening 
and have your hearing checked. The louder the volume, the less time is required before your hearing could 

be affected. 

Choking Hazards.

 This device contains small parts, which may present a choking hazard to small children. 

Keep the device and its accessories away from small children.

Avoiding Water and Wet Locations.

 Do not install the system in wet or humid locations without using 

weather protection. Take care not to spill any food or liquid on the device. In case it gets wet, unplug all 

cables, turn off the device before cleaning, and allow it to dry thoroughly before turning it on again. Do not 

attempt to dry the device with an external heat source, such as a microwave oven or hair dryer. A device that 
has been damaged as a result of exposure to liquids could be not serviceable.  If the device is exposed to 
rain or excess moisture, unplug the power cord immediately.

Keeping the Outside Clean.

 Handle the device with care to maintain its appearance. To clean it, unplug 

all cables and turn it off. Warning: unplugging the power cord is the only way to disconnect the power 
completely. Then use a soft, dry or slightly damp cloth. Avoid getting moisture in the openings. Don’t use 

window cleaners, household cleaners, aerosol sprays, solvents, alcohol, ammonia, or abrasives to clean 
the device. 

Carrying, Handling and Installing the device.

 The device contains sensitive components. Do not drop, 

disassemble, open, crush, bend, deform, puncture, shred, microwave, incinerate, paint, or insert foreign 

objects into it. If your device has been dropped or damaged, or if liquid has been spilled into the chassis, 

unplug the power cord immediately.

Do not operate speakers for an extended period of time with sound distortion. This is an indication of 

malfunction, which in turn can generate heat and result in a fire. 

To reduce the risk of overheating the device, avoid exposing it to direct sunlight and take care to do not 

Read all safety information below and operating instructions before using this device to avoid injury.
