Thank you for purchasing TOA's Ceiling Mount Speaker.
Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.
1. SAFETY PRECAUTIONS
• Before installation or use, be sure to carefully read
all the instructions in this section for correct and
safe operation.
• Be sure to follow all the precautionary instructions in
this section, which contain important warnings and/
or cautions regarding safety.
• After reading, keep this manual handy for future
reference.
WARNING
Indicates a potentially hazardous situation which,
if mishandled, could result in death or serious
personal injury.
• 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.
• Since the speaker is designed for indoor use, do
not install it outdoors. If installed outdoors, the aging
of parts causes the speaker to fall off, resulting in
personal injury. Also, when it gets wet with rain,
there is a danger of electric shock.

INSTALLATION MANUAL
• Do not use other methods than specified to mount
the bracket. Extreme force is applied to the speaker
and the speaker could fall off, possibly resulting in
personal injuries.
CAUTION
Indicates a potentially hazardous situation which,
if mishandled, could result in moderate or minor
personal injury, and/or property damage.
• Avoid touching the speaker'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 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.
