SECURITY PANEL

After setting the gain controls, you can install the security panel to prevent tampering and accidental misadjustment. After the knobs have been removed and the gain setting checked, install the security panel as shown in the general illustration to the left and on next page.

NOTE: The PL2A security panel has a viewing hole for the blue BI-AMP LED. DO NOT USE the PL2 security panel as it has no BI-AMP LED hole. The use of the incorrect security panel may result in damage to the BI-AMP LED. Ensure PL2A security panels are used with PL2A amplifiers.

INSTALLING THE SECURITY PANEL

1.Remove the gain control knobs. Do not pry on the knob as damage to the gain control could result.

2.Use a 9/64" or 3.5 mm hex key to loosen the screw.

3.Slide the right end of the security panel under the screw head.

4.Insert the tabs into the keyed portion of the ventilation slots, then slide the panel to the right so it locks in the slot.

5.Align the right end of the security panel with the chassis openings; tighten the screw to secure the panel. Do not over tighten.
