4. INSTALLATION

Step 1. Install a 1-gang electrical box in a wall or ceiling.

Step 2. Mount the AN-9001's Main unit to the installed electrical box.

Use the 2 screws (No.6-32UNC x 30) supplied with the AN-9001.

Note

The AN-9001 comes with 2 types of machine screws: No.6-32UNC x 30

(unified threads) and M4 x 30 (metric threads). Be sure to use correct

ones.

Step 3. Let both detents on the panel's rear into the detent insertion openings of

the Main unit.

Tips

For detent insertion, refer to the following points:

(A) Align 2 triangular marks on the panel with the extended line

connecting between Main unit's mounting screws.

(B) Align the panel's center hole with the Main unit's microphone.

Step 4. Rotate the panel clockwise.

The panel locks into place by rotating it about 20° in the "Lock" direction.

Note

Keep the AN-9001 as distant as possible from a sound source

(speaker, water supply pipe, or air conditioning).

If installed close to a sound source, the AN-9001 could sense it

as ambient noise to control the speaker sound volume.

5. REMOVABLE TERMINAL PLUG CONNECTION

Be sure to use the supplied removable terminal plugs for connections to the

removable terminal blocks.

Notes

• Be sure to use shielded cables for audio signal lines.

• Avoid soldering stranded or shielded cable, as contact resistance may

increase when the cable is tightened and the solder is crushed, possibly

resulting in an excessive rise in joint temperatures.
