• Install the unit only in a location that can

structurally support the weight of the unit and the

mounting bracket. Doing otherwise may result in

the unit falling down and causing personal injury

and/or property damage.

• Since the unit is designed for in-door use, do not

install it outdoors. If installed outdoors, the aging of

parts causes the unit to fall off, resulting in personal

injury. Also, when it gets wet with rain, there is a

danger of electric shock.

Indicates a potentially hazardous situation

which, if mishandled, could result in moderate

or minor personal injury, and/or property

damage.

CAUTION

• Avoid touching the unit's sharp metal edge to

prevent injury.

• To avoid electric shocks, be sure to switch off the

amplifier's power when connecting speakers.

• Do not operate the unit 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.
