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 above). There are three small raised “dimples” (see the figure below) 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 26 speaker is shipped unlocked.

Removing the Speaker from the Mounting Plate

To remove the speaker from the mounting plate, you must unlatch the locking mechanism.

1. Insert the security key into the keyhole of the speaker grille (see the previous section) and turn the key to the unlock position.

2. Remove the security key.

3. Apply pressure to the grille with your finger over the “dimpled” keyhole to unlatch the speaker from the mounting plate while lifting up on the speaker (see figure at right).

Press to Release

ATTENTION: To avoid damaging or scratching the grille finish, do not use tools or sharp instruments to depress the unlocking mechanism hidden behind the center of the grille.
