Note for Practical Information!
When using electric tool for screw mounting, adjust tension to prevent the dog screws being overly tightened.
It is further recommended to use moderate or low speed when tightening the dog screws.
If removal of speaker is needed for service, make sure to turn out front dog screws slowly until they “feel resist-
ant” -
At this point, the mounting clamps should be turned back in neutral position, and the speaker is ready to be
pulled out from the wall cut.
5. Connect the speaker to cables in the wall, and place
cabinet into the wall cut.
6. Turn the Torx screws on the front clockwise to acti-
vate the mounting clamps.
7. Check if speaker is perfect aligned.
8. Mount and align the grill, - and your install is done!
