3.Turn on the audio source and any associated devices. Follow the manufacturers instructions to adjust the source and device settings as desired to get the optimum audio output for your speaker application. It may be necessary to adjust the angle of the speaker (see steps 5 and 6 below) to get the best audio coverage area for your application.

4.

To adjust the angle of the speaker, carefully remove the

 

Extron logo on the front of the speaker to expose the front

 

locking access (see figure 3, item C, for location). To do

 

this, carefully pry the logo away with your fingers or use a

 

small flat head screwdriver (see figure 14), taking care not

 

to damage the front grill or the logo.

 

Gently pry

 

away logo.

5.

Insert the allen hex tool into the locking access, and

 

slightly loosen the hex cap screw. Adjust the speaker to

 

the desired angle (see figure 15), and torque the hex cap

 

screw down clockwise until snug, about 6 to 8 turns. The

 

speaker will sit securely in the desired position.

Turn clockwise to tighten.

NCheck that the speaker is secure and cannot be lifted from the wall mount assembly after locking it into place. If it does lift out, continue tightening down the hex cap screw until it is no longer possible to lift the speaker from the wall mount assembly.

6.

Replace the Extron logo, pressing it firmly into place.

NThe Extron logo can be fitted either horizontally or vertically.
