determined, fix the speaker mounting bracket to the base.
Note
The speaker's horizontal orientation can be adjusted after
the speaker has been installed.
Step 4. Fix the hexagon head bolts (one each on both sides)
loosely to the position indicated in the figure above.
Step 5. Connect a speaker cable to the speaker.

• Refer all installation work to the dealer from whom the unit was
purchased. Installation requires extensive technical knowledge
and experience. The speaker may fall off if incorrectly installed,
resulting in possible personal injury.
• Install the unit only in a location that can structurally support the
weight of the unit and the speaker. Doing otherwise may result in
the speaker falling down and causing personal injury and/or
property damage.
• Owing to the speaker's size and weight, be sure that at least two
persons are available to install the speaker. 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 speaker could fall off,
possibly resulting in personal injuries.
• Use nuts and bolts that are appropriate for the 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 speaker to fall, which could result in
personal injury.
Indicates a potentially hazardous situation which, if mishandled,
could result in death or serious personal injury.
WARNING
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.
•
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 that could cause the unit to fall, possibly causing
personal injury.
