1.
contacts using a small screwdriver (see the example illustration below) while observing the correct polarity.
NOTE: The positive (+) connector and the negative (-) connector are marked on the mounting plate.
Attach the mounting plate to the wall box (where used) or to the wall stud, using two mounting screws (see the
2.
example illustration below).
NOTE: The mounting screw holes in the mounting plate allow for some degree of play and lateral movement so that the
mounting screws may be aligned properly with the screw holes of the wall box.
Attaching the Speaker to the Mounting Plate
Step 1: Attaching the speaker
Position the rear mounting slot of the speaker above the catch tab of the adapter plate
and slide the speaker down into the mounting plate so that the speaker is secured in place
(see the illustration on the right). When properly seated, the speaker connections are
automatically made.
NOTE: By default, the speaker is set to the "unlocked" position.
After mounting, the speaker may be locked to the mounting plate by turning the key
to the locked position (see step 2).
NOTE: To avoid misplacing the key, store the key in a secure location for future use.
