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. NS-45E
