CAUTION
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.
• As a force of approx. 18 kg (39.68 lb) is applied to the
speaker receptacle at the time of speaker installation,
attach it in a location durable enough to withstand the
force. Doing otherwise may result in the unit falling
down, causing 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 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.
• Ensure that all screws are securely tightened. If they
are loose after installation, the unit could fall down,
possibly resulting in personal injury.
• To avoid electric shocks, be sure to switch off the
amplifier's power when connecting speakers.
• 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.
• Thin type wall mount speaker with 5" cone speaker unit
• Two-way speaker system employing a balanced dome
tweeter and elliptical horn for high-frequency sound
reproduction in combination with a 5" cone speaker
unit ensures high-quality sound. (BS-1034 and BS-
1034S)
• The speaker's smoothly curved surface in combination
with its straight lines permits it to blend in with virtually
all modern buildings.
• Equipped with a speaker receptacle, providing speaker
cable connection and installation ease.
• Equipped with a lock mechanism, preventing the
speaker from being detached easily after installation.
• In-wall wiring, exposed wiring, or bridge wiring
available for speaker cable connection
• The input power (impedance) can be easily changed
by the rear-mounted rotary switch. (BS-1034 and BS-
1034S)

connected to a 3-wire and 2-wire systems.
