■ATTACHING THE STANDS
Procedures
1. Put a screw through the inside hole on the stand and
screw it into the speaker at one of the outside holes on
the base of the speaker.
At this time, screw it untightly so that the stand can still
be moved.
2. Put another screw through the outside hole on the
stand, and screw it into the inside hole on the base of
the speaker.
3. Tighten both of the screws firmly.
4. Attach the leg to the bottom of the end portion of the
stand.
5. Attach the other stands to the other corners of the base
of the speaker in the same way and confirm that all 4
stands have been firmly attached.
Note
Be carefull not to apply force to the side of the
speaker, otherwise the speaker may fall causing
damage to the speaker or personal injury.
When placing the speakers, be sure to use the stands to
increase stability.
Use the 8 specified holes located on the base of the
speaker.
