WARNING
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
CAUTION
• Install the speaker only in a location that can structurally support the weight of the speaker and the mounting
bracket. Doing otherwise may result in the speaker falling down and causing personal injury and/or property
damage.
• Do not stand or sit on, nor hang down from the speaker as this may cause it to drop, resulting in personal
injury and/or property damage.
• Do not operate the speaker for an extended period of time with the sound distorting. This is an indication of a
malfunction, which in turn can cause heat to generate and result in a fire.
