CAUTION
When Installing the Unit
• Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface.
Doing so may result in the unit falling down and causing personal injury and/or property damage.
• 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.
• Owing to the unit's size and weight, be sure that at least two persons are available to install the unit. Failure
to do so could result in personal injury.
• Do not use other methods than specified to mount the bracket. Extreme force is applied to the unit and the
unit could fall off, possibly resulting in personal injuries.
• Use screws that are appropriate for the ceiling's or wall's structure and composition. Failure to do so may
cause the unit to fall, resulting in personal injury.
• Ensure that all screws are securely tightened. If they are not tightened or firmly secured after installation, the
unit could fall down, possibly resulting in personal injury.
• Use the specified mounting bracket in combination. Doing otherwise may cause the unit or component to fall
off, resulting in personal injury.
• Do not mount the unit in locations exposed to constant vibration. The mounting bracket can be damaged by
excessive vibration, potentially causing the unit to fall, which could result in personal injury.
When Installing the Unit
• When unpacking or installing the unit, be sure to handle it with two or more persons. Falling or dropping the
unit may cause personal injury.
• 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.
