Step 1. Attach the speaker receptacle to a wall.
[Notes on horizontal speaker mounting]
• Even if the speaker receptacle is attached horizontally,
the speaker may be tilted due to its weight unbalance
when attached to the receptacle.
• Be sure to attach the speaker so that its volume control
is positioned downward. (BS-634T only)
• When changing the logo direction, peel off the logo
carefully as it is affixed using double-faced tape. Then,
re-affix it in the right orientation.
[Exposed wiring]
Notch the top of the speaker receptacle using long-nose
pliers, then make connections.

If the supplied tapping screws are not appropriate for the
construction of wall, separately prepare the appropriate
screws.
Install the speaker receptacle referring to its "UP" mark.
Position the receptacle at the specified distance away from
any object above and below it for vertical speaker mounting.
Keep the same distance to the right and left of the receptacle
(positioned sideways) for horizontal speaker mounting. •
