When Installing the Unit
• 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.
When the Unit is in Use
• Do not operate the speaker for an extended period
of time with the sound distorting. Doing so may
cause the speaker to heat, resulting in a fire.
• Do not stand or sit on, nor hang down from the
speaker as this may cause it to fall down or drop,
resulting in personal injury and/or property
damage.
• Have the speaker checked periodically by the shop
from where it was purchased. Failure to do so may
result in corrosion or damage to the speaker or the
mounts that could cause it to fall, possibly causing
personal injury.
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.

2. GENERAL DESCRIPTION AND FEATURES
TOA's SC-615BS Paging horn speaker features an aluminum horn flare and stainless steel bracket for all-
weather durability. The TOA's unique oval shape horn enhances excellent speech clarity. Other feature
includes a newly developed diaphragm employing special heat-resistant polyimide film to prevent the
diaphragm from absorbing moisture and deformation. High speaker efficiency has also been realized by
minimizing the gap produced when the diaphragm bobbin is installed in the magnetic circuitry slit. The SC-
615BS is certified to the European Standard EN 54-24: 2008 and the International Standard ISO 7240-24:
2010, and is compliant with the British Standard BS 5839-8: 2008.
