Attaching the Speaker to the Mounting Plate
Step 1: Attaching the Speaker
NOTE: If a secondary attachment point is being used, see the “Attaching a
Secondary Support Cable” section on page 12 for installation details before
proceeding further.
ATTENTION: By default, the SM 3 speaker is shipped unlocked. When mounting
the speaker to the mounting plate, be sure that the speaker is unlocked. Failure to
place the speaker in the unlocked position will result in damage to the speaker lock
mechanism should an attempt be made to mount a locked speaker (see “Step 2:
Using the Security Key to Lock and Unlock the Speaker” on page 10).
Position the rear mounting slot of the speaker above the catch tab of the mounting plate,
then slide the speaker down into the mounting plate until a click is heard indicating that
the speaker is secured in place (see figure below). When properly seated, the speaker
connections are automatically made. Horizontal mounting is similar with only the orientation
of the speaker being different.
