Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.

• 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.

TOA's CS-154U outdoor speaker features a resin enclosure and stainless steel hardware for all-weather
durability. It is designed to offer the weather resistance and high efficiency of horn speakers combined with
the high sound quality of cone speakers. The CS-154U also employs a constant directivity horn for clear
sound output over the limited horizontal range of dispersion.
