pull it out carefully.
· The subframe is attached to the baffle frame by 4 external
screws. To detach it, unfasten those screws.
(for IW631 and IW651)
· The crossover networks is attached to the baffle frame by 4
external screws. To detach them, first disconnect the speaker's
wires.
Next remove the baffle frame. Then unfasten those screws.
· The tweeter is attached to the baffle by 2 external screws.
To detach it, unfasten those screws. When re-attaching it, face its
terminal rightward. [S-IW631-LR, S-IW831-LR only]
· The woofer is attached to the baffle by 4 external screws.
To detach it, unfasten those screws. When re-attaching it, face its
terminal lower right.
· Attach the speaker frame to the wall /ceiling, and
tighten the screws lightly (temporary attachment).
At this point the rotating clamp will rotate so that the rotating
clamp and frame are clamped on to the wall/ceiling.
Gently try pulling the speaker forward and check that all of the
rotating clamps have rotated outwards and are lightly clamping
to the wall/ceiling.
· Tighten the screws firmly using no more than the

P.SW: (RF-RM135 : rated 60 V)
P.SW has extreme positive resistance-temperature characteristics.
If an abnormal current flows to P.SW due to an excessive input or
unusual signal, P.SW heats up and the resistance rapidly increases.
With this function, the speakers are protected from excessive input
or unusual signal. The resistance value increases even when using
a soldering iron for repairing, so allow it to cool before using.
