Clamp the speaker to the C-ring by using a Phillips screwdriver to tighten the three

Clamping the Speaker to the C-ring
Each of the three locking arm screws use an Opti-Torque indicator ring that snaps
and separates from its plastic ring when the screw is tightened to the correct
torque. The indicator ring falls down the screwdriver shaft. When this occurs, stop
tightening the screw to avoid overtightening the locking arms to the C-ring.
Figure 36.
Stop Tightening when the Opti-Torque Indicator Ring Falls
ATTENTION:
To avoid damaging the speaker, do not overtighten the three screws.
