When Installing the Unit
• 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.
• 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 nuts and bolts that are appropriate for the 
ceiling's or wall's structure and composition. Failure 
to do so may cause the speaker to fall, resulting in 
material damage and possible personal injury. 
• Tighten each nut and bolt securely. Ensure that the 
bracket has no loose joints after installation to 
prevent accidents that could result 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.
• (F-1300B, F-1300BT, F-1300W, and F-1300WT 
only) 
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. 
• (F-1300BTWP and F-1300WTWP only) 
When installing the unit in the snowy area, take 
appropriate measures to prevent snow from lying 
on the unit. If the snow lies on the unit, the unit may 
fall, causing personal injuries. 
• Do not use anti-rust lubricant. If it contacts resin or 
rubber parts, they could deteriorate and cause the
unit to fall, possibly resulting in personal injury. 
• Do not install the unit where it is likely to be 
corroded in such places as bath rooms, indoor 
pools, or seaside. In such locations the bracket 
may be vulnerable to corrosion, eventually allowing 
the speaker to fall resulting in personal injury.
When Installing the Unit
• Never set the impedance switch to the "170 Ω" 
position when operating the speaker on 100 V line. 
Failure to follow this instruction could result in 
damage to the speaker or amplifier. 
• 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 the speakers.
When the Unit is in Use 
• Do not place heavy objects on the unit as this may 
cause it to fall or break which may result in 
personal injury and/or property damage. In 
addition, the object itself may fall off and cause 
injury and/or damage.
• 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.
• Do not stand or sit on, nor hang down from the unit 
as this may cause it to fall down or drop, resulting 
in personal injury and/or property damage. 
• Have the unit checked periodically by the shop 
from where it was purchased. Failure to do so may 
result in corrosion or damage to the unit or its 
mounting bracket that could cause the unit to fall, 
possibly causing personal injury.
