Handling and maintenance
• Do not expose the device to excessive dust or vibration, or extreme cold or
heat (such as in direct sunlight, near a heater, or in a car during the day), in
order to prevent the possibility of panel disfiguration, unstable operation, or
damage to the internal components.
• Do not place vinyl, plastic or rubber objects on the device, since this might
discolor the panel.
• When cleaning the device, use a dry and soft cloth. Do not use paint thinners,
solvents, cleaning fluids, or chemical-impregnated wiping cloths.
• When turning on the AC power in your audio system, always turn on the
power amplifier LAST, to avoid speaker damage. When turning the power off,
the power amplifier should be turned off FIRST for the same reason.
• Be sure to observe the amplifier’s rated load impedance (see
“Specifications”), particularly when connecting speakers in parallel.
Connecting an impedance load outside the amplifier’s rated range can
damage the amplifier.
• When using a high-impedance speaker connection, make sure the audio
signal is passed through an 80 Hz or above high-pass filter before being input
to the speakers.
• When connecting the speakers with high impedance, be sure that the total
rated input capacity of the speakers does not exceed the output power of the
amplifier.
• Do not swing the speaker by its carrying band.
• Do not place the speaker face down with the grille attached, as deformation of
the grille may result.
• When placing the speaker face down, always place it on a flat and smooth
surface.
• Do not touch the speaker driver unit.
●
Protective circuit
This speaker system has an internal protection circuit that shuts off the speaker
unit when an excessive input signal is applied. If the speaker unit emits no
sound, reduce the volume level of the amplifier immediately. The sound will
return automatically in several seconds.

Installing the Speakers
Install the speakers onto the ceiling with the supplied hardware.
Ensure that the strength of the ceiling rail is sufficiently strong.
Pre-installation (Preparation of the Cable)
Use stranded wire for cables attached to the ceramic terminal. Strip
their insulation as shown in the figure and connect them.
Note
Do not plate stranded wires by solder. Doing so will cause the wire to
break.
1.1
Put the supplied cutout template to the ceiling and draw a circle by
tracing it.
Make sure to use the cutout template so that hole is the correct
diameter.
Note
If you use a circular cutter, set the diameter with the cutout template.
1.2
Cut the hole by tracing the circle.
Be careful to prevent chips or powder entering your eyes while
cutting the hole.
2.1
Insert the two tile rails through the cut hole and place them on the
ceiling surface within your reach. Be sure that each tile rails are
oriented as shown below.
2.2
Insert the folded O-ring through the cut hole and open it in the ceiling.
