SM 28 Surface Mount Speaker • Installation
14
Using the Security Key to Lock and Unlock the Speaker
Insert the key into the center of the speaker grille and turn the key, as needed, so that
the speaker is in the unlocked position (see the figure below). There are three small raised
“dimples” (see the figure on the next page) on the grille surface that surrounds the keyhole.
Repeat this procedure, but set the key to the locked position to lock the speaker.
ATTENTION:
•
The key must be rotated to the unlocked position before the speaker is attached to
the mounting plate. 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
the speaker. By default, the SM 28 speaker is shipped unlocked.
•
La clé doit être basculée en mode déverrouillé avant le rattachement de l’enceinte
à la plaque de montage. Si l’enceinte n’est pas placée en mode déverrouillé, elle
pourrait subir des dommages au niveau de son mécanisme de verrouillage lors
de son montage sur plaque. Par défaut, l’enceinte SM 28 est livrée en mode
déverrouillé.
