Setting the Tap Selector Switch
(SM 26T model only)
For the SM 26T model, insert a small screwdriver through the upper left portion of the front grille, as shown below, to adjust the
tap selector switch to the desired setting.
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.
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 on the right).
