Step 1-1. Run the speaker cables from the wall through the base frame hole (21.6 mm in diameter), then strip

corresponding to AWG24 – 14)

Step 1-2. Mount the base frame on the wall using four screws.

Notes
• The speaker cannot be mounted if the base frame is not properly positioned. Ensure that the base

frame hole is situated on the upper side of the frame when mounted.

• Use nuts and bolts (not supplied with the unit for direct wall mounting) that are appropriate for the

structure and composition of the wall.

• When using two-gang electrical box, use either the supplied "M4 machine" or "Unified" screw

depending on the type of electrical box. 

• Protect the H-3WP from rain when installing it outdoors. (Refer to p. 10 "Waterproofing the base

frame.")
